Mountain bike shorts aren’t just gear—they’re the secret to riding all day in comfort and confidence. For women out there, the right pair blends thoughtful chamois, durable fabrics, functional pockets, and a fit that respects diverse bodies and riding styles.
Treeline’s editors spent 3.5 years riding over 20 pairs and reviewing 30 models across Colorado’s varied terrain—and even the iconic 100-mile White Rim Trail. They tested lounger lap-friendly baggies, thin liners, and everything in between, following real-world challenges like 90°F desert heat, sharp rock snags, and extended saddle time to find which shorts truly endure and perform.
What set the winners apart was multi-season comfort, finesse in fit (especially on and off trail with or without knee pads), reliable pocket placement, breathable yet durable materials, and waistband systems that stayed snug, adjustable, and comfortable through long miles and repeated use across hot and technical conditions.
Top Pick: The Outdoor Research Freewheel Ride Shorts emerge as the standout choice. Tested on hot, flowy rides and technical climbs in Colorado, they impressed with abrasion-resistant DuraPrint, a perforated and breathable back panel, plus a fit and size range (0–4X) that genuinely welcomes more riders.

The best women's mountain biking shorts
Best Women's MTB shorts: Outdoor Research Freewheel Ride Shorts
Sizes: 0-4X
Inseam: 11.5 inches
Pockets: Two zippered thigh pockets
Fabric: bluesign-approved 88% Nylon, 12% Spandex
What we liked: Comfortable, excellent fit, DuraPrint fabric detail adds durability, versatile, wide size range
What we didn’t: Not as lightweight as others
Outdoor Research has long been one of our favorite brands for outdoor apparel, from ski jackets and pants to softshells and sun shirts. They’ve now dipped their toes into the mountain biking scene with their first line of MTB-specific apparel. With the Freewheel Ride Shorts, it’s safe to say they nailed it. These are an incredibly comfortable, durable, and versatile pair of mountain bike baggies suitable for any day on the trail.
Compare prices of the Outdoor Research Freewheel Ride Shorts
-
The Freewheel Ride shorts are made with a stretchy and abrasion-resistant fabric that’s so comfortable on the bike we almost forgot we were wearing shorts when testing (especially when paired with the Velocio Mesh Bib Liner). The fabric is bluesign approved and has a UPF 50+ rating for sun protection and a PFC-free DWR coating for water resistance.
On the lower part of the outer thigh, the fabric is dotted with DuraPrint—an abrasion-resistant coating that helps minimize wear in areas like this that are most likely to brush up against tree branches or swipe rocks. On the back, just below the waistband, there is a panel of perforated fabric that adds breathability.
-
There is a zippered pocket on each thigh, one with a downwards sliding zipper and one that slides horizontally across. Both pockets have ample space for a large phone or snacks. The pocket placement is just right. We kept a phone in one of the pockets for just about every test ride and it never felt in the way while pedaling or descending.
The inseam of these shorts is 11.5 inches. They’re just long enough to work with knee pads, and the slightly longer hem design in the front helps avoid a gap. (If you ride with knee pads often, you may want longer shorts, like the Rapha Trail shorts, which have a 14.4 inch inseam.) The Freewheel shorts are very comfortable and not too long to wear without knee pads.
-
The fit of these shorts overall is excellent. The waist is comfortable and the legs have plenty of room for freedom of movement without being unnecessarily baggy. One of the reasons we like these shorts for our overall pick (compared to our previous winner, the Patagonia Dirt Roamer, now our best lightweight pick) is because of this versatile fit. The Dirt Roamer shorts are on the slim side, and that fit may not be for everyone. Others we’ve tested have often felt unnecessarily baggy in the legs. These seem to hit the sweet spot for all around trail riding shorts.
We found the Freewheel Ride shorts to run true to size. The waist adjustment on the shorts is a tab pull system (similar to the Patagonia Dirt Roamer shorts). It’s both easy to use and comfortable, and one of the least cumbersome waist adjustment options we’ve used.
We tested these shorts on several spring rides around Colorado, from cactus-speckled desert trails to flow tracks in the forest. They are breathable even on hot days (though if you want even lighter shorts, consider the Patagonia Dirt Roamers). The perforated back panel helps to mitigate moisture in what is typically one of the sweatiest areas on a ride, the low back. The shorts bead off water fairly well and we had no issues in light rain. After spilling a water bottle on the shorts, they dried very quickly after riding in the sun for a bit.
It’s worth reiterating again that, when testing these shorts on trail rides, we almost forgot we were wearing any shorts at all. They really are that comfortable.
Another thing we love about these shorts (and a lot of Outdoor Research apparel) is that they come in plus sizing as well. So, they are available from a 0 all the way up to a 4X (and it’s worth noting that there is a separate plus-size model, so the design is specific for plus-size folks). The only other brand with a comparable size range is Shredly. This wide range of sizing is another reason the Freewheel shorts get our best overall award.
-
If you’re looking for a versatile pair of mountain bike shorts that are at home on any trail, no matter the terrain, weather, or distance, make these your first choice. They are our top pick and likely what we’ll be riding in all summer long.
Best Lightweight Mountain Bike Shorts: Patagonia Dirt Roamer
Sizes: 0-18
Inseam: 12.5"
Pockets: 2 zippered outer thigh pockets
Fabric: 4-ounce 90-denier 86% recycled polyester/14% spandex with four-way stretch and a DWR (durable water repellent) finish
What we liked: Very comfortable, streamlined features, reasonable price, fair-trade sewn, well placed functional pockets, recycled fabric, Ironclad Guarantee for repair or replacement
What we didn't like: The trim fit may not be for everyone
We tested a heap of excellent mountain bike shorts for this story, and after miles of cruising flowy singletrack, grinding up dirt road climbs, and everything in between, the Patagonia Dirt Roamer shorts have earned their place as one of our favorites. These womens mountain bike shorts are among the most comfortable in our test and offer streamlined features while being incredibly lightweight and breathable. They are the best lightweight pair of mountain bike baggies.
Patagonia’s venture into the world of mountain bike apparel began with a small offering of athletic shorts and now features a whole line of bike-specific pieces for men and women—from baggies and liner bibs to jerseys and shell jackets. Over the years, we’ve tested multiple models of the women’s bike shorts, and with each iteration, they improved.
Compare Prices of the Patagonia Dirt Roamer
-
In the early years of the brand’s mountain bike offerings, the first pair of baggies we tested left some things to be desired—they were comfortable but lacked the fit and features we wanted in a good pair of overshorts. The second bike short we tested, a couple of seasons and updates later, nearly won our best overall for this story. We loved the baggies, but they came with a chamois liner that missed the mark, and you could not purchase the two separately.
Patagonia has made some notable updates to the Dirt Roamer, which is now sold individually (just overshorts, no liner, though you can purchase the Dirt Roamer liner separately). So, you can pair whatever chamois you please with it. (It’s worth noting that Patagonia’s liners are designed to integrate with these shorts.) And after years of Patagonia tweaking their designs for women’s mountain bike shorts, we think they nailed it with the newest version of the Dirt Roamer.
-
For the past few seasons, the Dirt Roamer shorts have held our best overall award. While we still think these are excellent shorts and remain a favorite, we think they are best suited for folks who prefer lightweight, breathable shorts and don’t mind a slimmer fit. The Outdoor Research Freewheel Ride shorts, now our best overall winner, offer a thicker fabric for more durability, a roomier fit, and a wider size range, seating them in our best overall spot.
Both are excellent shorts, and we’d say they’re equally comfortable. Pick these for the light weight and breathability and opt for the Freewheel shorts for all-around, everyday riding performance.
-
The Dirt Roamer shorts fall in the middle of Patagonia’s line of mountain bike baggies. While the Patagonia Dirt Craft shorts are more gravity -oriented and the Tyrolean shorts are built to be lightweight and minimal for cross-country rides and bikepacking, the Dirt Roamer is the all-around trail short. We did test the Tyrolean shorts and while they are Patagonia’s lightest and most minimal option for baggies, we prefer the fit and features of the Dirt Roamer.
With a 12.5-inch inseam, these womens shorts hit right at the knees and are long enough to work well with knee pads, but aren’t too baggy without them, either.
The light and stretchy fabric of the Dirt Roamer shorts is ideal for long, hot days with lots of pedaling. It breathes well and remains comfortable all day.
-
Good mountain bike shorts should be comfortable, and the Dirt Roamers have a barely-there feel that we love, especially on the climb. The waistband hits just right and stays in place without pinching; the waist adjustments are functional and sleek; the 4-way stretch fabric has a soft feel that strikes a nice balance between breathability and durability while offering freedom of movement on the bike.
The 90-denier polyester fabric of the Dirt Roamer is lightweight, breathes well, dries quickly, and has a DWR coating to fend off light precipitation. Stitchless, glued seams add comfort and minimize bulk and chafing. We found the shorts fit true to size but lean towards the slim-fit side. If you prefer a looser fit, consider the Outdoor Research Freewheel Ride shorts for a wider fit in the leg. (You could size up in these, but they are ultimately designed with an intentionally trim fit.)
-
When testing, we often reached for these shorts, from hot laps on singletrack after work to full-day mid-summer epics. When riding the 100-mile White Rim Trail, we reached for the most comfortable shorts to bring along for long days in the saddle under the hot desert sun, and the Dirt Roamers were at the top of the packing list.
They held up well to regular use on the trail and shined on sun-soaked climbs in 90-degree heat in the southern Utah desert. Because these shorts are made of thinner material, they are slightly less durable than thicker shorts in our test (like the Outdoor Research Freewheel or Wild Rye Freel), but this is an expected trade off and we’d still consider these durable shorts overall.
If you prefer more downhill and rowdy riding, consider different shorts. (One of our male testers acquired some holes in his pair after a good crash on the trail.) But if you’re in it for the climb or ride a lot in hot weather often, these are excellent shorts.
-
The pockets on the Dirt Roamer shorts are simple but functional. Each zippered pocket comfortably stores a phone or snacks without inhibiting movement when pedaling. The pockets also have a slot on the inside that passes through, so you can access pockets on the compatible Dirt Roamer Liner shorts (we did not test the liner shorts). We like the streamlined zippered pocket design of these shorts. The placement is just right, and we never found ourselves wishing for additional on-body storage.
-
We think the value of the Dirt Roamer shorts is good. They’re not the most expensive in our test, but they’re also far from the cheapest. However, with that price tag, you get a comfortable, well-designed short that’s built to stand up to many miles on the trail. Best yet, it's among the first Fair Trade Sewn mountain bike shorts out there, and it's made of 86% recycled polyester.
We think the Dirt Roamer will serve you well if you’re looking for a trail short that emphasizes a lightweight, streamlined design along with comfort and breathability. These shorts were our favorite lightweight pair in the test for hot weather and long climbs that serve up all the features you need with none that you don’t.
Best Upgrade MTB Shorts: Rapha Trail Shorts
Sizes: XS-XL
Inseam: 14.4"
Pockets: 1 zippered left leg pocket
Fabric: 88% nylon/12% elastane
What we liked: the most comfortable we tested, bluesign and Oeko-tex certified fabric, the fabric breathes well, includes a patch kit
What we didn't like: price, the length makes it less versatile for all types of riding
From the first minute we slipped the Rapha Trail Short mtb shorts over our liner for a ride, we knew they would be a favorite in the test. Rapha is known for designing sleek, high-quality cycling apparel, and last year they dove into the mountain bike scene with a splash. Rapha’s Trail Shorts were the only ones in our test that beat out the Patagonia Dirt Roamer for overall comfort, and like the Dirt Roamers, the Trail Shorts also have streamlined features that we love.
View the Rapha Trail Shorts
-
The Trail Shorts are made with a Bluesign, and Oeko-Tex certified nylon fabric with 4-way stretch. That fabric, paired with a low-profile, stretchy waistband, makes these bike shorts the most comfortable in our test. A 13.5-inch inseam length means these longer shorts pair very well with knee pads, never leaving a gap between the thigh and pad. Their inseam is longer than others in our test and we found that to be an advantage.
Even though these shorts are very comfortable while pedaling, the length makes them better suited to the trail and more gravity-oriented styles of riding, or simply ideal for ladies who prefer a longer inseam in their bike shorts. Those looking for shorts that are not quite as long should consider the Patagonia Dirt Roamer for a more versatile fit.
The Trail Shorts fit true to size and err slightly on the slim-fitting side, though we found them to have plenty of room in the legs. The waistband is incredibly comfortable and forgiving, with a stretchy panel at the back.
There is no waist adjustment on these shorts and no belt loop, but we never felt the need for this. We found just the right amount of storage in the Trail Shorts-with two zippered side pockets that feature a phone sleeve inside. The pocket design is out of the way, so they don’t inhibit pedaling.
-
We tested these shorts on hot sunny days and cool, rainy evenings, and they were comfortable for it all. The length means they’ve got enough protection for cooler rides or when you want to keep your legs unscathed on the trail, but the lightweight fabric breathes well when the temps heat up.
Over several weeks of testing, we never encountered any durability concerns with the Trail Shorts. However, mountain biking often means spills on dirt or snags from branches while trail riding, and sometimes even the best apparel gets chewed up. While we haven’t needed it yet, we appreciate the included patch kit that Rapha throws in with these shorts. We’re all about making good gear last as long as possible. Rapha also offers a repair service if the damage is beyond the scope of the patch kit.
Overall, we think the Trail Shorts are a thoughtfully designed, excellent pair of MTB shorts that will please any mountain biker with a penchant for comfort and longer inseams. They are, however, among the most expensive in our test.
If you’re looking for a better balance of value, comfort, and features, consider our overall winner from Patagonia or, if budget is your top priority, the Fox Ranger shorts. But if you want the Cadillac of mountain bike shorts and don’t mind the price tag, Rapha has created a short we think you’ll love.
Best Chamois Liner: SHREDLY Yogacham
Sizes: 00-24
Inseam: varies based on size
Pockets: n/a
Fabric: anti-microbial
What We Liked: Incredibly comfortable, good pockets, reasonably priced
What We Didn’t: Like all chamois, these shorts don’t offer as much durability or coverage as baggy shorts do.
Finding a genuinely comfortable chamois layer can feel like picking the lesser among evils: the padding can feel like a diaper, the legs might ride up, and the waistband pinch. Enter the SHREDLY the YOGACHAM.
These shorts are designed to feel as comfortable as your favorite pair of yoga pants while having the padding to keep your nether parts happy on even the longest rides.
We tested the SHREDLY the YOGACHAM side-by-side with the SHREDLY Biker Cham. The Biker Cham was our previous winner. After a year of testing, ultimately, we found the YOGACHAM to be better. It has pockets and more coverage, making it more versatile.
Compare prices of the SHREDLY Yogacham
-
The YOGACHAM features an eight-paneled articulate design for maximum stretch and breathability, with an antimicrobial padded layer that fends off stenches and keeps you comfortable in the saddle without adding too much uncomfortable bulk. As with the MTB Curvy short, we like that Shredly keeps all different body types in mind when designing their shorts.
-
While not quite as breathable as the 7Mesh Foundation Short, the Yogacham has a comfortable fit and a wide range of sizing.
Plus, the fabric is thick enough that you can wear these as a stand-alone short if you want.
The fit of these shorts is excellent-the waistband doesn’t create the dreaded muffin top, but it also doesn’t fall or fold over during a ride. Pair them with Shredly’s curvy shorts for ultimate comfort.
-
The Yogacham shorts are some of the most comfortable bike shorts we’ve tested, without a doubt. That includes many pairs of road bike shorts that we’ve also taken for spins over the seasons.
These shorts are made with a nylon/spandex blend fabric that feels buttery soft on the skin.
They’re not as compressive as other bike shorts in this style, but they’re just snug enough to stay put even on long days in the saddle.
The wide waistband is sturdy without being restrictive. It lays flat, doesn’t roll, and doesn’t dig in at all.
The thighs have small beads of silicone on the inside of the edges to prevent the shorts from riding up, and that functions fairly well—not quite as good as other road bike shorts, but we didn’t have issues with the shorts riding up too far. The only thing we could wish for with these shorts with the fit is more compression in the fabric, but that’s far from a deal breaker.
SHREDLY Bikercham. It is the most comfortable and plush padding of any of the shorts we’ve tested over the years.
Most Stylish MTB Shorts: Wild Rye Freel
Sizes: 0-18
Inseam: 12"
Pockets: 2 hand pockets and 1 zippered leg pocket
Fabric: 88% nylon and 12% spandex, UPF 50 rating and DWR treatment
What we liked: fun patterns, comfortable and flattering fit, durability, length is good for wearing with or without knee pads, UPF 50 rating
What we didn't like: thicker fabric, feels more structured
There are a lot of people out there who want a bike short that looks fun and feminine but can still take the abuse of riding hard. The women-owned business Wild Rye creates shorts with a great fit, durable materials, and fun patterns that keep you looking good while you're out on the trail - and we think the Wild Rye Freel short hits the mark for a great pair of over shorts.
Compare Prices of the Wild Rye Freel
The generous zipper pockets on the Wild Rye Freel are big enough to fit even large phones.
-
In testing, we found the 12” inseam length and articulated knee on the Wild Rye Freel fit seamlessly with knee pads. But we liked that these bike shorts aren’t too long, so you can choose to wear them with or without the knee pads.
There isn’t a waist adjustment on the Freel, but it does have belt loops. We found these shorts to fit slightly on the small side. While they stretch over time, we recommend sizing up for more comfort with a liner underneath.
As of this year, Wild Rye now offers this short in extended sizes (up to a 24), called the Freel Flex.
The Freel's newer reinforced waistband reduces stretching over time. If you've purchased a Freel in the past and sized down, the newer models fit more true to size.
The Wild Rye Kaweah is a similar and older model that was popular but has a slimmer cut and less stretch. The Freel is better suited for curvy bodies, which is one reason we recommend it over the Wild Rye Kaweah.
-
Wild Rye seems to nail it on fabric and that is one of the reasons why their jersey snagged the top spot in our Best MTB Jerseys guide.
That same attention to detail can be found in their MTB shorts. The nylon and spandex material in the Wild Rye Freel make this short both stretchy and durable, and they stand up well to any weather with their 50 UPF rating and water repellent treatment.
Compared to other shorts in our test, the Wild Rye Freel has a thicker fabric that inspires confidence to put the shorts through the wringer. But though they’re thicker and a bit more structured, they still have a comfortable stretch for pedaling.
-
The Freel shorts have 2 hand pockets and one zippered leg pocket for your phone.
This year, the Freel Wild Rye updated the hem of the Freel to reduce the hem roll that you may see mentioned in some older customer reviews.
-
We loved riding in these shorts on some of our favorite Colorado trails and found the Freels to have a nice balance of sturdiness, stretchy comfort, and style. Wild Rye is a favorite among mountain bikers for a good reason–it's a brand that manages to pull off making women's mountain bike clothing that performs and has fun with the style at the same time. You'll find the brand in our Women-Owned and Women-Founded Outdoor Brands guide.
Best Plus Size MTB Shorts: SHREDLY Limitless 11” Short
Sizes: 2-24
Inseam: varies by size
Pockets: 2 hand pockets, 2 zippered thigh pockets
Material: ecoMove polyester and spandex blend with 4-way stretch, recycled material
What we liked: availability of sizing, yoga waistband is comfortable, made with recycled fabric
What we didn't like: could have a more tailored fit
Finding a mountain biking short that fits well can be challenging, especially for riders with curves. We love that SHREDLY has shorts designed for all shapes and sizes with the SHREDLY Limitless 11” shorts (previously called the SHREDLY MTB Curvy). It’s designed to fit bikers with curvy hips and strong, thick thighs to ensure comfort and freedom of movement.
Compare Prices Of The SHREDLY Limitless 11” Short
-
The waistband on this short is designed to mimic yoga pants, making this MTB short one of the most comfortable baggies in our test.
Previous versions of the SHREDLY MTB Curvy and Shredly MTB Short were favorites but did not have any waist adjustment. This updated version now has an internal drawcord to help dial in the fit.
We found the Limitless Shorts to fit true to size. With an 11-inch inseam (depending on the exact size you get) these do work with knee pads, though we had a gap when riding. Shredly also offers these same shorts in a shorter version with the Limitless 7” shorts.
-
These shorts' recycled eco-Move 4-way-stretch fabric is comfortable and fairly breathable, though not as breathable as others in our test, like the Patagonia Dirt Roamer or the Rapha Trail Short.
-
The Limitless shorts have two hand pockets and two zippered leg pockets that fit any phone. Older models of these shorts had only one Velcro thigh pocket (plus the two hand pockets). We love that they now have zippered thigh pockets on each side.
-
SHREDLY takes a fun approach to their design with wild prints and bright colors with plenty of options, including more subtle solid colors for those who prefer to be less flashy on the trail. We love the inclusive sizing and overall comfort of these shorts.
-
Are you looking for a chamois that fits your curves like these Shredly baggies? Consider the SHREDLY Yoga Cham or SHREDLY Biker Cham. They’ve got an ultra-comfortable waistband, cute design, and go up to a size 3X.
Note: Retailers don’t tend to stock as many pairs of these shorts as other models, so if your size isn’t in stock at one retailer, check another one.
Best Budget Short: Fox Ranger
Sizes: XS-XL
Inseam: 12”
Pockets: 2 hand pockets; one zippered leg pocket
Material: DWR polyester/spandex/polyester/elastane
What we liked: function and quality for the value, durability of the baggies, includes everything you need (baggies + chamois)
What we didn't like: chamois could have more padding, other shorts have more features
Getting into a sport like mountain biking can take a real toll on your bank account, but you still need a good pair of shorts to ride in. The Fox Racing Ranger short is a great kit to get you started and keep you going. For under $100, you get baggies and a chamois, which we think is a great deal.
View the Fox Ranger
-
The baggies are made of a polyester blend and have a DWR coating to shed precipitation and mud, which is an excellent bonus for shorts at this price. The waistband on the baggies has waist adjustments that we found to be a tad finicky but ultimately still did the job.
With a 12-inch inseam, these shorts are long enough to work with knee pads, though cyclists with longer legs may get a gap. The Ranger shorts have two regular hand pockets and one zippered leg pocket that’s large enough to fit most phones.
-
The chamois that comes with the Ranger is also made of a stretchy polyester blend material. The padding is thin but still sufficient for average rides—and ideal for those ladies who want minimal padding. The legs on the chamois are just tight enough: comfortable, but they rarely ride up at all.
The waistband on the chamois is the only main downside to these shorts. It’s made of a thicker-woven material that isn’t as soft or stretchy as other shorts in this review, like the Shredly Biker Cham or 7Mesh liners.
-
After testing these shorts on various rides along Colorado singletrack, we’re impressed with how well they perform at this price point. They have features we appreciate, offer good durability, and are comfortable. If you’re willing to spend more money, you’ll get more comfort and better features with some of the other shorts we give awards to in this review.
But overall, we think the Ranger short is an excellent value. We've tested other shorts in this price range and these give you the most bang for your buck. The baggies are durable enough to be your everyday workhorse short, and the chamois gets the job done even if it’s not the fanciest or most comfortable. If you’re on a budget and looking for one great pair of shorts, these are it.
Best Bib Liner: Velocio Mesh Bib Liner
Sizes: XXS-3XL
Inseam: Varies by size
Pockets: Two thigh stash pockets
Fabric: Full mesh; 75% Polyamide, 25% Elastane
What we liked: Incredibly comfortable and breathable, good chamois pad, easy to use the bathroom in
What we didn’t: Leg bands are on the tight side and can create a “sausage leg” look
Bibs: Most cyclists either love them or hate them. If you’re a mountain biker in the former category, put the Velocio Mesh Bib Liner at the top of your list. This is a pair of bibs with all the details mountain bikers love, like breathable mesh, a plush chamois, barely-there straps, and even pockets. Plus, the thoughtful design includes an easy way to pee on the trail without having to completely disrobe. For the ladies who prefer the comfort of bibs under their baggies, this pair takes the cake.
View the Velocio Mesh Bib Liner
-
These bibs are designed specifically to be worn under a pair of baggies, meaning they’re ultra thin, light, and breathable. (This also means they’re quite skimpy and revealing without baggies on top.) The mesh material is stretchy and soft, and breathes very well, even on hot days.
The straps on the bibs are seamless, making them some of the most comfortable bibs we’ve tested. While we were often excited to remove the straps after a long ride with other bibs, these ones we forgot even existed.
The chamois is cushy and breathable. It’s not the plushest chamois pad we’ve ever used, but it’s close and we found it to be thick enough even for long rides when most of the day is spent in the saddle.
The legs stay firmly put and don’t ride up at all with these shorts. While the bibs fit true to size, the leg openings are slightly on the snug side for ladies with thicker quads. It was visually noticeable in our testing, but once we were riding it didn’t bother us at all.
-
There are two stash pockets on the thighs of these shorts, and they’re placed low enough that they’re fairly easy to access from the bottom of your baggies. While we didn’t always use these in testing, they came in handy when we wanted to store emergency snacks for long rides in the backcountry.
Another nice feature with these shorts is what Velocio calls their FLYFree design. The bibs don’t go up very high in the back and the material is very stretchy, so this makes it fairly easy to pull them down to use the restroom in the woods. It’s not quite as easy as regular shorts, but it’s far easier than with most other bib designs and a win in our book.
-
We tested these bibs on long and short rides on trails around Colorado. They are especially nice on hot days since they have a mesh body, but we enjoyed them for just about every ride. The bib design is overall more comfortable around the waist than regular chamois shorts liners since it minimizes bulk under the waistband of baggies.
These bibs offer a good value. While they’re not the cheapest mountain bike bib liners on the market, they are priced well for how comfortable and functional they are.
Additionally, Velocio offers repair services for their apparel and a crash replacement policy. If you have small snags, holes, or are in need of other repairs, you can contact them and request a repair for the price of shipping. If your apparel is damaged beyond repair, they offer a crash replacement discount to replace it.
If you’re a bib lover and want a pair specifically for mountain biking, these are the best for the ladies on the trail.
Best maternity bike shorts: Wild Rye B.O.B. Maternity Chammy
Sizes: 0-18
Inseam: Varies by size
Pockets: Two side pockets
Fabric: 79% recycled polyester, 21% Spandex
What we liked: Finally, a good pair of maternity bike shorts!
What we didn’t: Limited use case
Since the dawn of time (that time being when pregnant women started riding bikes), women have had to get creative with technical apparel to accommodate growing bellies that come with pregnancy. For many outdoorsy women, pregnancy doesn’t stop us from doing the things we love, and we shouldn’t have to be limited by the gear we have access to.
Compare prices of the Wild Rye B.O.B. Maternity Chammy
Thankfully, Wild Rye now makes a maternity-specific pair of bike shorts designed for people who are 5-8 months pregnant. Sure, it’s sometimes possible to slide into your regular bike chamois shorts while your belly is bursting, but it’s not always very comfortable (trust me—I did it before the B.O.B. existed). These shorts have a wider waistband that stretches with your belly and a chamois pad that’s reliably comfortable like other Wild Rye shorts. The cherry on top: thigh pockets that fit a phone or snacks. You can read more about Outdoors Clothes for Pregnant People in our guide to everything we’ve found that has worked so far.

We think these models are also worth considering if you need special performance features (like downhill mountain bike shorts) or have a preference for fair trade sewn clothing.
Flylow Eleanor
Sizes: XS-XL
Inseam: 12.5”
Pockets: 2 zippered on back of leg; 1 Velcro pocket on leg
Fabric: 40 UPF, quick dry
In our previous run of this story, we gave the Flylow Eleanor our top award for overall comfort, style, and features. The Eleanor has been discontinued but you can still find it on steep discounts and we think they may be worth considering, especially if you're on a budget.
We still think these shorts are a great option, but after a few season of rides in them, we encountered some durability issues that hold us back from fully recommending them. After an entire season of riding in the Eleanor often, the snap closure ripped out from the shorts rendering them useless. We’ve also tested the men’s version of these shorts and got a small hole in the butt of the fabric after only a few rides.

Sizes: 2-14
Inseam: 11.5"
Pockets: 1 zippered left thigh pocket
Fabric: Schoeller® Stretch Double Weave: 90% Nylon 10% Spandex, 167 g/m2 with Ecorepel DWR Finish
We reached for the Stio OPR shorts often during our testing and nearly handed them our best overall award.
The design is thoughtful with a tailored fit, good pockets, breathable and stretchy DWR-coated fabric, and a comfortable waistband. The 11.5-inch inseam makes them comfortable for long rides with lots of pedaling. And while they can be worn with knee pads, they’d work better if they were just a little longer.

There are two main reasons that these shorts didn’t end up as our top pick. First, while the waist adjustments are good (hook and loop design), they aren’t quite as reliable or streamlined as the ones on the Outdoor Research Freewheel or Patagonia Dirt Roamer. Second, we like the simple and functional pocket designs with dual zippered pockets on both the Outdoor Research and Patagonia shorts. However, if you also like having hand pockets for use off the bike, then consider these.
Nonetheless, the OPR shorts were among the most comfortable and well-designed shorts in our test, and we love the style and color options too. Ultimately, these are another excellent pair of baggies that are a great choice for all-around trail riding.
Sizes: XXS-3X
Inseam: 13 inches
Pockets: Two zippered thigh pockets
Fabric: 79% Polyamide, 21% Elastane
What we liked: Very lightweight, breathable, good warranty and repair options
What we didn’t: Belt and loop waist adjustment
The Velocio Ultralight Trail Shorts are a great option for riders who want a pair of baggies on the lighter side. They’re made with a durable yet light stretch woven fabric that’s comfortable on the climb and the descent. With a 13-inch inseam, they work well both with and without knee pads. There are two zippered thigh pockets that hold things comfortably while pedaling.
The fit of these shorts runs very close to true to size, with a little more room in the legs while being slightly snug at the waist. If you’re on the fence, we’d recommend sizing up. Compared to the Patagonia Dirt Roamer shorts—our lightweight winner—these have a bit more room in the legs, which some riders may prefer. (The Dirt Roamer shorts do have a fit that leans on the slim side.)

For the waist adjustment, the Ultralight Trail Shorts have belt loops and come with a stretchy Arcade belt. One of the main reasons we like the Patagonia shorts better than these is because of the waist adjustment design. The waist is simply more comfortable without a belt. And, for this being a lightweight option, we think the belt and loop option adds unnecessary bulk and weight to the shorts.
But, the light and stretchy fabric of these shorts is great for long, hot days on the trail. We also love the colorways available for the Velocio shorts. We also appreciate that Velocio offers repair service for their apparel so you can keep your gear in rotation for longer. So, if you prefer a belt to other waist adjustment systems and want a lightweight pair of baggies for trail riding, these are a great option.
Sizes: XS-3X
Inseam: 7-inch
Pockets: 2 thigh pockets
Fabric: Nylon/spandex blend
If you’re the type of rider who prefers to skip the baggies and opt for just one bike short layer, you’ll want something comfortable, durable, and that ideally still has great features like pockets. And the Shredly Biker Cham shorts have just that. They’re a buttery soft pair of stand-alone chamois shorts that pair the same padding as the Yogacham with a thicker material so they can be worn without baggies or overshorts.
Whether you just like mountain biking without baggies, or you want a pair of shorts that can transition from the mountain bike to the road bike, these are great–we just like the Yogacham (also made by Shredly) better.

Sizes: XS-XL
Inseam: 12.5"
Pockets: 2 hand pockets, 2 zippered side with phone sleeve
Fabric: nylon/elastane
These shorts proved to be a tough competitor with the Rapha Trail Short for our upgrade pick, but the ultra-comfortable waistband and included patch kit were some of the reasons the Raphas took the cake in that category. However, 7Mesh-a small company out of British Columbia-has made an excellent short here, with durable and breathable stretch fabric, a length that works well with or without knee pads, and excellent pocket design and well-designed features.

Sizes: XS-XL
Inseam: 4-5" (shorts)
Pockets: none
Fabric: nylon/elastane/elastic (recycled content)
We tested both of these liners from 7Mesh and were pleasantly surprised by each one. The Foundation Short has a lower rise than most chamois liners we’ve worn, but it’s incredibly comfortable. The chamois padding holds up to long days in the saddle, and we love the super breathable mesh fabric for hot rides.
When we first looked at the Foundation Brief, we were suspicious of padded underwear. However, after a few short rides, we’re thoroughly impressed. The padding is minimal, and these are built for shorter rides or days when you’re mostly descending and spending little time in the saddle. They’re comfortable and functional for days when you don’t need a full chamois.

Sizes: XS-XL
Inseam: 11"
Pockets: 2 zippered side hand pockets; 2 zippered leg pockets
Fabric: 86% polyester/14% spandex UPF 20
We mentioned the Fox Racing Ranger shorts as a great budget kit, but if you’re looking for just a baggy short at a good price, the Zoic Navaeh is a great option offering durability, comfort, and great customer reviews at a friendly price point. These runner-ups for best budget baggie should be on your radar, especially if our other winners are out of stock.

Sizes: 0-18
Inseam: 12"
Pockets: 2 small hand pockets; 1 zippered side pocket that fits phone
Fabric: recycled nylon, elastane, DWR finish, fair trade certified sewn
For those looking to buy their baggies and chamois as a kit, the Patagonia Dirt Craft is a solid option at a reasonable price. We tend to prefer purchasing the baggies and chamois separately (see more on why below), but kits can be a convenient way to purchase everything you need for mountain biking.
Compare Prices of the Patagonia Dirt Craft
The Dirt Craft baggies have a great fit, stretchy fabric, and breathability. We're also excited that they're the first mountain bike apparel that's 100% Fair Trade Sewn Certified.
While the waistband and padding were comfortable on the chamois, but the legs rode way too much for our liking. The chamois have since been updated and we haven't had a chance to test them yet.
Verdict: We prefer the Dirt Roamer Baggies version, which won our overall award. While the Dirt Craft shorts are more gravity-oriented and the Tyrolean shorts are built to be lightweight and minimal for cross-country rides and bikepacking, the Dirt Roamer is the all-around trail short. We think for most riders, the Dirt Roamer is going to be a more comfortable fit with all the features you need at a reasonable price.
Sizes: 24- 31”
Inseam: 5.5 - 6"
Pockets: 2 hand, 2 back
Fabric: stretch denim: cotton, elastane
If you want the ultimate casual, relaxed style on and off the trails, the Ripton Jorts serves it up. These “performance jorts” are stretchy denim shorts explicitly designed for biking and other outdoor activities. We liked them for shorter rides-they’re surprisingly comfortable when pedaling-and good street style off the bike. That style comes at a price, however, and while we dig these shorts, we think they’re a bit spendy for cutoff jean shorts. Additionally, sizing tops out at 31”, so it’s not as size-inclusive as other brands.

Sizes: XS-XL
Inseam: 12”
Pockets: left zip pocket, right thigh zip pocket
Fabric: 4-way stretch nylon (90% recycled), 10 % Spandex with Dry Now wicking tech
We love the sustainability initiatives behind Picture’s business, and this past season they launched their first line of mountain bike apparel. We tested the Vellir shorts on summer singletrack rides around Breckenridge, Colorado.
View the Picture Vellir Stretch
They’re a comfortable and stylish pair of mountain bike shorts that stood up well to use on the trail. However, they’re lacking in one major compartment: pockets. The shorts have ample pocket storage, but the placement is awkward, making it uncomfortable to carry items like snacks or a phone while riding. Other features in the shorts did not stand out enough to overcome this issue. (And good pockets are important!) However, if you always ride with a pack and rarely use shorts pockets while riding, these are an option worth considering for their comfort, style, and sustainability.
The Vellir shorts are made with 90% recycled nylon and 10% spandex, offering good freedom of movement while pedaling and enough durability and protection for the downhill. A PFC-free DWR treatment also helps to shed moisture.
On first glance, the buckle closure on the waist looks cumbersome, but it’s actually quite comfortable as long as your hip pack belt doesn’t interfere. There’s a hand pocket meant for a phone on one side and a thigh pocket on the other, though the placement of both is awkward for pedaling. Laser-cut holes help with ventilation on hot days. Ultimately, while these are a stylish-looking pair of shorts made with sustainability in mind, Picture needs to work out a few design issues in order for these to make them a winner.
Sizes: 0-18
Inseam: not specified
Pockets: none
Fabric: 80% Nylon, 20% Spandex
What we liked: Comfortable fabric, versatile for use with or without baggies
What we didn’t: Not very compressive
If you prefer to ride without the weight of baggies, or if you want a bib chamois that is versatile enough to take from the road to the trail, then the Baddie Bibs fit the bill. These bibs are great on road rides and the fabric is thick enough to be worn without anything else. But, they’re also sleek enough to be worn under a pair of baggies. The chamois pad is comfortable enough for rides up to a couple of hours and the material is soft and breathable.

WHY DO I NEED MTB SHORTS?
Unlike cycling shorts which are typically one-piece form-fitting shorts, mountain bike shorts are layered, consisting of a base layer short with a padded liner short, called a “chamois” or “chammy,” and an outer loose-fitting short, often called “baggies” or “overshorts.”
While road cyclists are concerned with sleek and minimal attire that helps with aerodynamics, mountain bikers want shorts that offer comfort and style while also being durable for long rides on the trail.
The padded chamois layer keeps you comfortable for long days sitting on a bike saddle, while the outer shorts offer durability that helps resist wear from tree branches, crashes, and anything else the trail may throw your way.
Mountain biking chamois shorts are often made of thin, stretchy fabric and sometimes mesh material for superior breathability. Most will not have pockets or additional features (though some do) since you’ll have those on your baggy outer shorts.
Most chamois layers are shorts, though there are a few bib versions available on the market. The concept is the same as far as padding and breathability, but the bib design adds comfort to the shorts by not having a traditional waistband that can cinch the tummy or fold over on itself.
The baggy layer is usually made of a thicker material, often with added water repellent treatment for more protection against the elements. Pockets, adjustable waistbands, and other features will often be included on baggy mountain bike shorts.

What to look for in women's MTB shorts
Some mountain bikers prefer to buy their chamois layer and baggy shorts separately, depending on preferred fit and style, while others like the convenience of buying their shorts as a kit (meaning the chamois and baggies are sold together as a set).
Whether you’re looking for individual pieces or a set with chamois and baggies, there are a few things to look for in a quality pair of women’s mountain biking shorts.
The author testing chamois-style mountain bike shorts by Pearl iZumi. This style of shorts tend to have less bulky padding and feel more comfortable, but are best suited for shorter rides on smoother trails.
HOW TO CHOOSE A MOUNTAIN BIKING CHAMOIS
When looking for a good padded chamois layer, the padding is one of the most important factors. Some chamois shorts will have more padding than others, and often it comes down to personal preference.
If your bike rides typically only last an hour or two, or if you simply prefer the fit and feel of minimal padding, then look for a chamois that does not have bulky padding. The upside to a chamois with more minimal padding is that it may feel more comfortable and natural to wear.
But having less padding ultimately means less cushion. If you plan to spend long days in your bike seat, consider wearing shorts with thicker, more dense padding. We won’t get into the gruesome details of what can happen to your tender areas. Trust us—you want that extra padding for long rides.
If you want to dig into the details, REI has some great additional info on why wearing a padded chamois short is so important.
There are a few other important factors to consider when choosing a chamois aside from the padding itself.
BREATHABILITY & COMFORT
You’ll want it to be breathable and comfortable since you’ll likely be wearing it underneath a pair of baggy mountain bike shorts. Look for stretch and mesh for ultimate comfort and breathability.
COMFORT

Though this will often require you to try on the shorts before you buy, make sure the waistband on your chamois is comfortable.
It should not pinch your stomach.
The fabric shouldn’t roll over on itself. Chamois shorts with wide waistbands (like the Shredly Biker Cham) or a slanted “V” shape in the front often make for the most comfortable fit. A bib chamois eliminates comfort issues with the waistband and mitigates the problem of hiking your shorts up, leading many mountain bikers and cyclists to prefer this style.
Lastly, the legs of your chamois layer should fit snugly without being restrictive and should never ride up your legs. Some chamois shorts have silicone beading around the leg openings to help keep them in place—this is helpful, but not always necessary.
If the shorts are the right length, fit, and design, they should not ride up. (Try them on before buying if you can, or check the return or exchange policy if you’re ordering online. (Backcountry offers free return shipping. Evo can make returns in-store or by mail, but will deduct shipping costs. As of 2022, REI charges $5.99 for return shipping costs, overriding a previous free returns policy).
HOW TO CHOOSE MOUNTAIN BIKE BAGGIES
When looking for a good pair of baggy mountain bike shorts, you’ll still want to consider comfort and breathability, but durability will be paramount since this will be your outer short layer.
STRETCHY, DURABLE FABRIC
A good pair of baggies will usually have some stretch for comfort and freedom of movement, along with a durable fabric (like a thick polyester) that won’t snag against tree branches and can stand up to falls. Most mountain biking baggy shorts also have an added water repellent treatment, so mud and precipitation shed easily off the shorts. Some models, like the Fox Ranger, come in a breathable and a water-resistant version, to allow for riding in cooler autumn or spring weather.
ADJUSTABLE WAISTBAND
Many baggy mountain bike shorts also have an adjustable waistband that helps fine-tune fit to keep your shorts from sagging down or cinching too tight. (Our favorite waist adjustment is the BOA dial on the now discontinued Pearl iZUMi Elevate short.)
The author testing the 7Mesh Glidepath MTB shorts in Colorado
POCKETS
Lastly: pockets. Having great pockets on a pair of mountain biking shorts is a big bonus factor. Pockets mean you may not need to bring a pack on shorter rides or that you have better access to your phone, keys, wallet, or snacks (although we definitely don’t recommend storing your MTB glasses in your pocket!).
The best pockets have a trifecta of features: large enough to fit a phone, zippers to keep things secure, and placement that lets you pedal freely. (We love the pockets on the Patagonia Dirt Roamer because they nailed this trifecta in the design.)

How to Fit Mountain Biking Shorts
There are mountain bikers who don’t identify as men and women, but we’re working within the reality that clothing sizes and shapes are categorized this way. We always recommend that regardless of how you identify, to not feel confined to what’s on the label and choose technical clothing that works with your body and feels comfortable when you move.
Your chamois layer should fit snug without being restrictive. Most mountain bikers find that a high-waisted chamois layer is most comfortable. One reason is because it holds everything in when you’re on your bike. It means that the waistband on your baggies won’t hit in the same place as your chamois waistband. Most chamois shorts will land somewhere between mid-thigh and just above the knee. Generally, you don’t want your chamois or baggies to fit too short (like running shorts would) because it will be uncomfortable while pedaling and often cause chafing.
As the name implies, baggy mountain bike shorts should fit on the looser side. This allows for freedom of movement when you’re pedaling hard uphill or going fast downhill. Most baggies will land at the knee or just above it. You’ll want this for protection when mountain biking. Some shorts will be slightly shorter and more form-fitting, which is ideal for cross-country riding, while others will have a longer and baggier fit, which is great for riders who prefer the downhill or like to wear knee pads. We love both the Wild Rye Freel shorts and Patagonia Dirt Craft because they have a versatile fit that is formed enough to be flattering while being long enough to pair with knee pads.
It’s important you know whether your MTB shorts are baggies, chamois, or a kit that includes both. The Fox ranger women’s MTB shorts (left) comes as a kit that includes baggies and chamois. Pictured here are the baggies that come included. The YOGACHAM chamois (right) are a liner short only and do not include baggies.
CHAMOIS AND BAGGIES: BUYING INDIVIDUAL PIECES VS. BUYING A KIT
You’ll find in this article that a few of our picks for the best women’s mountain biking shorts are sold as separate pieces (meaning the baggies do not come with a chamois) while others are sold as a set (baggies and chamois sold together).
Buying your baggies and chamois shorts as a kit can often save money, and it makes things simpler when selecting a pair of mountain biking shorts. However, this means that you don’t have the option to choose a particular chamois layer to go with a different pair of baggies. If you already have a chamois layer that you love or know of a particular one you want, then it’s often best to buy your baggies and chamois separately so that you can tailor the fit and style to your preference.
Ultimately, the decision comes down to personal preference and what your priorities are. If your top priority is budget, then going with a kit like the Fox Racing Ranger short is a great option.
But if you’re looking for a specific chamois layer that will fit perfectly and have plenty of cushion, and a baggy short that has the features you need for your style of riding, then buying separate pieces is the way to go.
Buying separately may cost more money, but you’ll have a kit tailored to your fit and needs.
If you are committed to mountain biking and know you’ll be riding your bike for the long haul, then consider spending more money upfront on gear that fits and functions well. In the long run, it’ll likely save you more money since you hopefully won’t be replacing your shorts as soon due to poor fit or quick wear.
FAQ
-
Mountain bike shorts typically consist of two layers: a padded chamois liner and baggy outer shorts, while road bike shorts are single-layer tight-fitting spandex with built-in padding. MTB shorts like the Patagonia Dirt Roamer offer durability and protection from trail hazards with features like DWR coatings and reinforced fabric, while road shorts prioritize aerodynamics and moisture-wicking. Mountain bike chamois liners are often made from thinner, more breathable materials since they're worn under baggy shorts, whereas road shorts use thicker fabrics suitable for standalone wear. The baggy outer layer provides pockets, weather protection, and a more casual appearance off the bike.
-
Buying separately allows better customization for fit and comfort, while kits offer convenience and value. Our testing shows separate pieces work best for serious riders - you can pair the Shredly Yogacham (our best chamois) with any baggy shorts that fit your style and riding needs. Kits like the Fox Ranger shorts offer good value under $100 for beginners, including both chamois and baggies. However, if you have specific fit requirements or prefer a particular chamois padding level, buying separately ensures you get exactly what works for your body. Consider your budget, experience level, and how much customization matters to you.
-
Chamois should fit snug like a second skin without being restrictive, while baggies should be loose enough for freedom of movement. The chamois waistband should sit comfortably without pinching - high-waisted options like the Shredly Yogacham often work best. Baggy shorts should allow easy pedaling without excess fabric flapping, with inseams typically 11-13 inches to work with or without knee pads. Avoid shorts that are too short (causing chafing) or too loose (creating drag and discomfort). Brands like Outdoor Research Freewheel and Shredly offer extended sizing from 0-4X to accommodate different body types.
-
Never wear underwear under chamois or padded bike shorts, as this defeats the purpose of the chamois and increases chafing risk. The chamois is designed to be the only layer between you and the saddle, providing a smooth, friction-free surface. Adding underwear creates additional seams that can cause chafing and prevents proper moisture-wicking. Cotton underwear especially traps bacteria and moisture, creating conditions for saddle sores. The antimicrobial properties of quality chamois like those in Shredly and Velocio shorts are specifically designed to work directly against your skin.
-
An 11-13 inch inseam provides versatility for riding with or without knee pads, with specific needs varying by riding style. Our testing shows 12-13 inch inseams like the Patagonia Dirt Roamer (12.5") and Rapha Trail Short (14.4") work best with knee pads while avoiding gaps. Shorter 7-inch options like some Shredly models work better for cross-country riding without pads. Longer inseams provide more protection and coverage but may feel too baggy for some riders. Consider your primary riding style - gravity/enduro riders benefit from longer shorts, while XC riders may prefer shorter, less restrictive options.
-
Padding needs depend on ride duration, saddle comfort, and personal preference, with thickness ranging from minimal to substantial. For rides under 2 hours or if you prefer minimal bulk, lighter chamois like the 7Mesh Foundation Short work well. Longer rides (3+ hours) benefit from substantial padding like the Shredly Yogacham, which offers plush cushioning without feeling like a diaper. New riders often need more padding initially, while experienced riders may prefer minimal padding for better bike feel. Consider your bike fit and saddle - well-fitted bikes require less padding than poorly fitted setups.
-
Bib shorts eliminate waistband issues and provide more comfortable weight distribution, while regular shorts offer easier bathroom access. Bibs like the Velocio Mesh Bib Liner use shoulder straps instead of waistbands, preventing the chamois from sliding down and eliminating pressure points around the waist. They're particularly beneficial for longer rides and riders who experience waistband discomfort. However, bibs require more effort for bathroom breaks and some riders find the straps restrictive. Regular chamois shorts offer more convenience but may shift during rides and create waistband bulk under baggy shorts.
-
Proper fit, quality chamois, and avoiding cotton underwear are key to preventing chafing. Choose chamois that fit snugly without bunching - loose chamois move and create friction points. Apply anti-chafing cream sparingly to high-friction areas before long rides, but well-fitted shorts shouldn't require cream for rides under an hour. Ensure your bike fit is correct, as poor positioning increases pressure and movement. Replace worn chamois promptly - old padding loses its shape and protective properties. Keep shorts clean and dry between rides to prevent bacterial buildup that can cause skin irritation.
-
Quality MTB shorts work well for other cycling disciplines and some outdoor activities, though design differences affect performance. Chamois designed for MTB like the Shredly Biker Cham can work for road cycling, commuting, or spin classes, though road-specific padding may be more comfortable for long road rides. Baggy MTB shorts work great for casual cycling, hiking (without chamois), or general outdoor activities. However, running in chamois isn't recommended due to different movement patterns. Some versatile options like the Wild Rye Freel transition well from bike to casual wear, while technical pieces are best reserved for cycling.

Care and maintenance tips
Mountain bike shorts take a beating on the trail, but with proper care, they'll serve you well for years of riding. Here's how to keep your chamois and baggies in top condition.
Washing your MTB shorts
Chamois shorts require special attention since they're made of technical, often delicate materials. Always wash them in cold water on a gentle cycle to preserve the fabric and padding. Never put chamois shorts in the dryer—the heat can break down the padding and damage the stretchy materials. Instead, hang them to dry or lay them flat. This is especially important for high-end chamois like the Shredly Yogacham or Velocio Mesh Bib Liner.
Baggy shorts are generally more durable, but cold water washing will help preserve any DWR coatings and prevent colors from fading. Most baggies can handle the dryer on low heat, but air drying extends their lifespan and keeps the fabric looking newer longer.
Always turn shorts inside out before washing to protect any printed graphics or logos, and use a gentle detergent. Avoid fabric softeners, which can interfere with moisture-wicking properties and DWR treatments.
Post-ride care
Don't let sweaty, muddy shorts sit in your gear bag for days. Rinse off excess dirt and hang them up to air dry as soon as possible after your ride. This prevents odors from setting in and keeps mud from grinding into the fabric fibers.
For particularly muddy rides, give your shorts a quick rinse with cold water before tossing them in the hamper. This simple step prevents soil from setting into the fabric and makes washing more effective.
Extending gear life
Many brands offer repair services that can significantly extend the life of your shorts. Rapha includes a patch kit with their Trail Shorts, and brands like Patagonia and Velocio offer repair services for torn fabric or broken zippers. Take advantage of these services—it's better for your wallet and the environment than replacing gear prematurely.
For minor snags or small holes, a fabric repair patch can work wonders. Keep a small tube of seam sealer handy for any seam issues that develop over time.
Storage tips
Store your shorts in a cool, dry place away from direct sunlight. UV rays can break down technical fabrics over time, and heat can damage elastic fibers. If you're storing gear for the off-season, make sure everything is completely clean and dry to prevent mold or mildew.
Don't store chamois shorts compressed or folded tightly for long periods, as this can affect the padding's shape and effectiveness. A simple hang or loose fold works best.
How we researched and tested
We tested over 30 pairs of mountain bike shorts for women over 3 years. We tested the most promising models—baggies, chamois liners, and kits—to see how each piece fits, how the chamois layers hold up on long rides with lots of saddle time, and how functional the pockets are on baggies, and more.
To get an idea of how these shorts fit on different bodies, we had riders of different body shapes and sizes test these shorts. We polled riders on their favorite shorts. We even tested during our pregnancy to see how these shorts fit our body's many different shapes.
With biking shorts, we feel that comfort and fit (along with durability and style) are important features. Those features are hard to assess from behind a computer screen, even when customer reviews are available.
That's why we tested from cactus-speckled desert trails to flow tracks in the forest. We tested on long, hot days with lots of pedaling. We tested bike shorts while riding the 100-mile White Rim Trail. We tested on some downhill and rowdy riding. We tested on cool, rainy evenings. We tested on singletrack trails in Colorado and Utah, as well as long, hot race training rides, and even on road bike rides along the rec path. One of our testers even took these shorts on the Great Divide Mountain Bike Route from Banff, Canada to Mexico–over 3,000 miles!
