Best Women's Running Shirts of 2023

THE BEST WOMEN’S TOPS FOR RUNNING: TANKS, T-SHIRTS, LONG SLEEVES

September 7th, 2023

To find the best running shirts, the author tested over 20 women’s running shirts on trail runs, paved trails, neighborhood runs, and everything in between.

As a long-time competitive runner (from D1 college track and cross country to road marathons to trail ultramarathons) who coached cross country and track, I’ve put thousands of hours into running clothes. I’m here to guide anyone purchasing running shirts on what to look for and what makes a quality shirt for running.

People of all ages, genders, sizes, and abilities have unique concerns about what clothing they workout in. While I couldn’t test every running shirt and tank top of the hundreds on the market, I personally tested the 14 top-rated ones on runs on trails, parks, and streets to see how they compare to find the best shirts and tanks for most runners. 

After testing in the heat and sun, cool mornings, gym workouts, everyday activities, roads, and trails, I judged shirts to find winners for the best women's running shirts. I also have answers to some FAQs about choosing the best running shirts for you. Between testing running clothes and Treeline Review’s guide to choosing the right running gear for you, the goal of this article is to guide you to your best running wardrobe investments.

The winners

Nathan 2.0 dash short sleeve

Best overall women's running shirt: Nathan 2.0 Dash Short Sleeve Shirt 

Best for: road running, trail running, workouts, gym, hot weather

Available sizes: XS-XL

Sleeve lengths available: short sleeve only

Fit: Relaxed

Fabric:  58% Nylon, 35% Polyester, 7% Elastane

What we liked: Lightweight fabric that wicks sweat and doesn’t stick

What we didn’t like: Not much other than I want it in a tank, too

The Nathan 2.0 Dash Short Sleeve shirt’s weight and feel on the body made it stand out during testing. The short sleeve shirt is light, soft, and doesn’t cling when wet. It feels like what I imagine wearing Mithril (any Lord of the Rings fans out there?) feels like-impossibly light and powerful.

I’m not a big shirt-wearer on summer runs (I prefer tanks), but I want this in every color. I literally whispered, “I’m obsessed,” to myself mid-run.

NATHAN 2.0 DASH SHORT SLEEVE SHIRT

A woman running on a dirt road in the mountains

We pushed hard on runs wearing the Nathan Dash 2.0. The lightweight material has plenty of airflow to keep us cool during hot days.

The fabric-a mix of nylon, polyester, and elastane-makes this shirt breathable and cool for summer runs. The elastane adds stretch I particularly appreciate when I want to use my shirt to wipe the sweat off my face during a run. Its relaxed fit helps with airflow and does not cling to the skin. 

I’m not a big shirt-wearer on summer runs (I prefer tanks), but I want this in every color. I literally whispered, “I’m obsessed,” to myself mid-run.

My biggest issue with this running top was more of a flaw on my end. Despite living in a city with 300 days of sunshine yearly, I wore a black shirt. The black was soaked in the sun and was a little warm; if that concerns you, I would go with another color. Additionally, as someone who prefers tanks, I would love to see this fabric combination in tank form.

To find the best running shirts, the author tested over 20 women’s running shirts on trail runs, paved trails, neighborhood runs, and everything in between.

The Nathan 2.0 Dash short sleeve shirt has just the right amount of stretch to use the shirt to wipe sweat off the face during trail runs.

This shirt, more than any, reminded me of what happens when you invest in quality clothing. I tested other (frankly, more expensive) tops and suffered unraveling over a couple of runs and washes, whereas the 2.0 Dash Short Sleeve proved hardy. A look at the customer reviews on Nathan’s website shows comments similar to mine, as well as an assurance the shirt provides good coverage for a running vest pack or hydration pack and doesn’t ride up.



Best long sleeve running shirt:

Patagonia Long Sleeve Capilene Cool Daily Shirt

Patagonia Long Sleeve Capilene Cool Daily Shirt

Best for: road running, trail running, cold weather (long sleeve), hot weather (tank)

Available sizes: XS-XXL

Fit: Standard

Fabric: Recycled polyester jersey and 50% polyester, 50% recycled polyester jersey

Sleeve lengths available: sleeveless tank, short sleeve, long sleeve

What we liked: Good coverage, light, breathable, comfortable

What we didn’t like: could be looser at the bust and arms

The Patagonia Long Sleeve Capilene Cool Daily shirt is our winner for best long sleeve running shirt. This lightweight long sleeve shirt is so breathable and comfortable, and fits much more comfortably than its short sleeve counterpart. The material is loose enough to encourage airflow, while still doing its job to keep you warm on cooler days. You could easily layer beneath or on top of this shirt, making it versatile for various temperature conditions.

PATAGONIA LONG SLEEVE CAPILENE COOL DAILY SHIRT

The author tested the Capilene Cool Daily knit on cool running days in Denver and on warm, sunny days (because of its sun protection).

The author tested the Capilene Cool Daily knit on cool running days in Denver and on warm, sunny days (because of its sun protection).

The Capilene Cool Daily knit is soft and quick-drying with sufficient stretch; their miDori™ bioSoft finish (a plant-seed-based multipurpose fabric softener) wicks sweat and is intended to maintain long-term softness. The HeiQ® Pure odor control feature can help keep the funk at bay, offering 17-45 UPF protection against UV rays. It's a lightweight 3.7 oz. Plus, with Patagonia, you can be sure of their Fair Trade Certified™ sewing practices and lifelong quality promise.

The MiDori® bioSoft fabric wicks sweat, and HeiQ® Pure odor control is a nice feature. I traveled around Europe for a month and didn’t always have access to laundry facilities. I brought both the Patagonia Capilene and the Rabbit EZ Tee long sleeve, and the odor control of the Patagonia was a noted difference between this shirt and the EZ Tee. I was a lot less smelly in that shirt.

Patagonia Capilene Long Sleeve Option 3

Patagonia designed this shirt with minimal stitching to prevent chafing. It’s made from recycled polyester materials, and is Fair Trade Certified™ sewn, which we love.

The Patagonia Capilene is available as a long-sleeve hooded version, which is praised in our Best Sun Shirts guide. And if you don't like sleeves, there's also a tank.

Patagonia Capilene Long Sleeve

Of all the shirts we tested, the Patagonia Capilene Daily also has the most colors and designs. It's available in 18 colors and graphics, with hood and without. 

While I enjoyed the shirt, a bigger-busted person may need to test it for themselves before purchasing. Fortunately, with Patagonia’s Ironclad Guarantee, the customer service is great, and returns, repairs, or exchanges are always an option. They will repair, refund, or exchange any item for any reason. This shirt is high quality, though, and well worth the price.

We also tested the short-sleeved version of the Capilene, which we didn’t love love for its fit–loose on the body but a little too snug at the bust and arms. We don’t recommend the short-sleeve Capilene over the other shirts unless you are particularly committed to Patagonia’s eco-friendly practices. In any case, we were pleased with the long sleeve. The fit and material is well-suited for cool runs, and layered with other clothing or on its own.


Best for Cool Weather:

Janji Helio Light Tech Long Sleeve

Janji Helio Light Tech Long Sleeve

Best for: road running, trail running, cool and cold weather, sun protection in temperature weather

Available sizes: XS-XXL

Fit: Standard to looser

Fabric: 100% polyester with HeiQ® Fresh treatment

Sleeve lengths available: sleeveless tank, short sleeve, long sleeve

What we liked: very quick dry, good at sweat-wicking, doesn't cling when sweaty, looser fit makes it good for layering

What we didn’t like: swoop neck can make layering more challenging

Janji’s Helio Light Tech long sleeve is our Best Shirt for Cold Weather because it is lightweight and moisture-wicking, making it incredibly comfortable over long runs in cooler temps. The looser fit makes it a good option for layering on colder runs, or breathable and cooling on more moderate or temperate runs. 

The fabric is 100% polyester and finished with HeiQ® Fresh treatment for odor control. The knit helps prevent the material from clinging when wet. This is a versatile, comfortable, quality long sleeve running shirt, and it’s surprisingly warm for how lightweight it is. Or, to put it another way, it's surprisingly lightweight for how warm it is.

JANJI HELIO LIGHT TECH LONG SLEEVE

This was a close second as winner of Best Long-Sleeve Shirt but the Patagonia Capilene Cool is tough to beat when it comes to temperature versatility. The Capilene performs slightly better in varying cool temperatures compared to the Janji Helio long sleeve.

I also didn’t love the swoop neck of the Helio–it made layering a short sleeve underneath feel a bit awkward–though that comes down to a personal preference. In any case, this is a great long sleeve that still plays in heavy rotation in my winter running wardrobe and is a favorite of mine on cold days.


Best for extreme cold weather:

Tracksmith Fells Turtleneck

Tracksmith Fells Turtleneck 

Best for: cold days, trail running, road running, running in high wind, running in the snow or rain

Available sizes: XS-XL

Fit: standard to loose, turtle neck

Fabric: merino wool blend

Sleeve lengths available: long-sleeve only

What we liked

What we didn’t like

I’ve long admired Tracksmith’s style–their technical clothing often looks like the kind of clothing I’d wear casually but with performance features made for running. The Fells Turtleneck absolutely falls into that category. But its style isn’t all it has going for it–the Fells Turtleneck is both warm and breathable, wicking moisture and preventing you from either overheating or getting cold from holding too much sweat. It's made of a merino wool blend that stays warm when wet but still breathes well. The high neck can act as a neck gaiter, too, for those exceptionally cold days.

TRACKSMITH FELLS TURTLENECK

The Tracksmith Fells Turtleneck is the best running shirt for very cold days when the extra warmth is motivation to get out the door.

The Tracksmith Fells Turtleneck is the best running shirt for very cold days when the extra warmth is motivation to get out the door.

Made of merino wool, the Tracksmith website puts it better than I could, “It’s temperature-regulating, odor-repelling and dries in a flash, with the comfort and easy-going style of a turtleneck you’d pair with jeans.” 

They aren’t lying–I ran in this mostly in 20-30-degree weather in the mountains and felt incredibly comfortable. When I sweated, it dried quickly, leaving me dry at the end of the run, which is important when you stop moving and are somewhere cold.

And before I’d run a single step in this shirt, I absolutely paired it with jeans and ran errands. It’s so stylish I couldn’t wait to wear it. Plus, it has thumb holes, which is always an added bonus, especially in extreme cold weather.

You can read more about why we like merino wool so much in our Best Baselayers guide and our Best Hiking Socks guide. Merino is well noted for its breathability, warmth when wet, comfort, softness, and natural anti-bacterial properties that keep odors at bay. And while we tested other merino running shirts, the Tracksmith Fell did the best job of keeping us warm–but not too warm–on the coldest of runs.


BEST WOMEN'S RUNNING TANK TOP:

Flylow Daily Tank

Flylow Daily Tank

Best for: hot weather, summer running, when you'll sweat, sun protection

Available sizes: XS-XL

Fit: regular to relaxed

Fabric: Intuitive™ Solar IQ, 92% polyester, 8% spandex

Sleeve lengths available: tank

What we liked: light, breathable material, fit not too tight, excellent sun coverage for a tank top, cut prevents chafing from hydration pack, SPF protection, material doesn't smell, durability

What we didn’t like: price

The Daily Tank by Flylow Gear is our new winner for best women's running tank. The material felt light and breathable, and the fit was not too tight while providing great coverage for protecting the shoulders from the sun and preventing chafing from hydration packs

Of all the other tanks we tested, the Flylow Daily Tank is most comparable to our previous Best Women’s Tank winner, the Oiselle Flyout Tank, which is our winner for Best Plus Size Running shirt. While the two tanks are similar in style and feel, the Daily Tank edged out the Flyout for best tank due to its SPF 30-rated protection and more durable quality of fabric.

FLYLOW DAILY TANK

I’ll admit, I was shocked that a company founded by two male skiers who wanted better ski clothes would make a women’s running tank that I preferred over one from a woman-owned running clothes company. But the shirt’s SPF 30-rated material not only feels light, comfortable, and breathable, but it doesn’t pill like the Flyout tank is inclined to do, sometimes frustratingly quickly.

Flylow Daily Tank With Hydration Pack Option 2

The back of the Flylow Daily tank is cut so it doesn’t chafe when you wear a hydration pack.

The Ionic+ antimicrobial-treated fabric on the Flylow tank also “self-cleans,” which means fewer washes. (I couldn’t believe it, but I ran, hiked, mowed, and ran again in this shirt without washing it and it never smelled or felt dirty on me.)

The back of the tank isn’t racerback, so much like the Flyout Trail Tank, it’s a good option for those wearing hydration packs. I experienced no chafing on the trails while wearing mine.

Flylow Daily Tank

The Flylow Daily tank has great quality fabric that doesn’t pill or snag.

The Flylow Daily Tank is $9 more than the Oiselle Flyout. Both are great running tanks. If you’re already spending that much on a tank, I believe the superior quality of the Daily Tank material is worth the extra cost, if they offer it in your size (the Oiselle is available up to size 26, whereas the Daily Tank is only available to XL). I rotate through both tanks frequently and maintain both are great options.


Oiselle Flyout Racerback tank

Best Plus Size Running Shirt: Oiselle Flyout Tank

Best for: hot weather running, plus size runners, using with hydration vest (trail tank cut), cold weather running (long-sleeve option)

Available sizes: 2 - 24/26 (plus sizes available)

Sleeve lengths: racerback tank, tank top, short sleeve, long sleeve

Fit: Racerback or Trail Tank stye

Fabric: HoverFit fabric (polyester/Tencel/spandex)

What we liked: Lightweight, wicking fabric that cools

What we didn’t like: Possible sizing inconsistencies and a heftier price tag

The Oiselle Flyout wins our award for Best Plus Size Running Shirt because of the size availability and dedication to making the same high-performance, well-designed shirt for plus-size runners.

The previous winner of our Best Running Tank category, the Oiselle Flyout Tank has been a long-time, easy favorite of mine. While the Flyout is wonderful–comfortable, lightweight, breathable–it was just edged out by our new winner–the Daily Tank by Flylow Gear–due to its occasional tendency to snag or pill. Nevertheless, this tank comes in a good range of sizes, and Oiselle’s mission of fostering inclusive running community keeps this tank a winner that everyone–of all body types–should consider.

OISELLE FLYOUT RACERBACK TANK

The Oiselle Flyout Racerback is lightweight, moisture-wicking, quick-drying, and cool. It also is stylish-looking, even when you’re running in the mountains where there is no one to see you!

The Oiselle Flyout Trail is a lightweight, moisture-wicking, quick-drying, and cool.

The Flyout Tank is lightweight, moisture-wicking, quick-drying, and cool. Oiselle keeps style in mind when designing their clothes, and this tank is no exception; the fit is tailored and comfortable, and the colors are appealing. Additionally, because the Oiselle Flyout tank is multipurpose — great for hot weather and under hydration packs (we’ll get into that more below) — it also wins our award for Best Running Shirt for Hot Weather category.

For this guide, we tested both the Oiselle Flyout Racerback Tank and the Oiselle Flyout Trail Tank. The cuts are slightly different, but the fabric is the same.

The HoverFit fabric blend is moisture-wicking, lightweight, and keeps the body cool. The spandex woven in the fabric adds a comfortable stretch, and the mesh-like material allows for more airflow. These features make the Flyout tank top (or the Flyout short sleeve shirt) excellent for hot weather, as well as a good base layer under a running jacket.

Because Oiselle designed the Trail Tank cut with hydration packs in mind, the material covers more of the back to help prevent chafing on sweaty days where drinking enough water is essential. The Racerback cut has less material, so runners who aren’t wearing hydration vests may prefer it for hot weather. No matter which cut you go with, this all adds up to explain why the Flyout won our award for Best Hot Weather Shirt.

The fit on the Flyout Trail style tank seen here is loose without being baggy, which provides plenty of airflow. The Racerback style tank has a similar design, just with a racerback back.

Both the trail tank cut and the racerback cut of the Flyout tank top fit loose without being baggy, allowing airflow and a more tailored look than the other tanks we tested. The Trail Tank is snugger than the Saucony Stopwatch Singlet (read more about that below), which can be nice for those who run with hydration packs and don’t want the shirt material bunching.

The neckline hits a few inches below the neck for both tanks, making it more comfortable on runs than tanks with higher necklines, like the Brooks Distance tank (review below).

The Flyout tank is also one of the most stylish tanks we tested. The fit is nice. The colors are appealing—and that’s true for shirts of all sizes and both the Racerback and Trail Tank cuts. Oiselle has the greatest size variety of any brand I tested, and they make sure the same high-performance fabrics, colors, and designs are available for runners of all sizes.

The Flyout Tank is also available as a t-shirt and long-sleeve, so if you don’t just want to wear the tank as a base layer during colder months, you can also get the same fabric in shirts with more coverage.

The Oiselle is stylish-looking, even when you’re running in the mountains where there is no one to see you!

A complaint I’ve noticed with this tank (and other clothing options with Oiselle) in customer reviews is that occasionally someone will order their usual size and find it suddenly fits differently. It took a while to notice the shirt I was testing was a size up from my usual. 

While I was comfortable, I might size up with this brand. My rule of thumb is to check the customer reviews with this brand一people have consistently been honest and accurate in their feedback. I’ve also seen customer reviews and experienced the occasional tendency for this material to snag. Worst case scenario, remember that Oiselle offers returns on unworn, unwashed clothing within 30 days of purchase.

Despite the possible hesitancy in sizing, the tank is undeniably great. And with a more inclusive size selection, this is a great option for most body types.


Hoka Glide Tank

Best Cropped Running Shirt: Hoka Glide Tank

Best for: hot weather running, gym work outs, running in stuffier environments

Available sizes:  XS-XL

Fit: Slim

Fabric: 100% recycled polyester

Sleeve lengths available: T-shirt, 3/4 length, tank

What we liked

What we didn’t like

The Hoka Glide Tank has a surprising cut that bewildered me at first. It has a cropped hem in the back and standard hem in the front, which I haven't seen on many running tanks. A friend explained that tucking in the back of a tank/shirt into a sports bra is a gym trend. I can’t help but wonder if Hoka is leaning into the trend. 

As skeptical as I was, I ended up liking this tank a lot more than I thought I would. The material is lightweight and breathable, and the, um, unique hemline actually created a nice airflow while running that kept me cool. Plus, as my friend had explained to me, this fit is meant to highlight your backside, so if that’s your thing you may appreciate this look.

HOKA GLIDE TANK

This tank wouldn’t be my standard go-to simply because the fit–while nice for the gym or stuffier environments–is niche. If you like the fit and style of this tank, though, this may be your all-around favorite.


Saucony Stopwatch Singlet best budget running shirt

Best affordable women's running shirt:

Best for: Road running, track running, trail running

Available sizes: XXS-XXL

Fit: Standard fit tank

Fabric: 100% recycled polyester

What we liked: Lightweight, mesh-like material for better airflow

What we didn’t like: Less “features” and more basic

At only $28, the Saucony Stopwatch Singlet tank is one of the least expensive tops we tested while being one of the most comfortable and cool. The airflow keeps you cool with a mesh-like design, and the fabric stretches just enough. The tank covers enough if you enjoy wearing tanks with hydration packs, as it’s not an actual racerback design. Plus, the color options are *so cute*.

SAUCONY STOPWATCH SINGLET

The Saucony Stopwatch tank performs well and we liked it almost as much as shirts twice its price.

The Saucony Stopwatch tank performs well and we liked it almost as much as shirts twice its price, delivering great value for runners on a budget.

The 100% recycled polyester is a feel-good option for sustainability, especially as few of the tops we tested offer that. Polyester is moisture-wicking, so even if it doesn’t offer a copyright blend of engineered fabric, it still works at a more affordable price. 

This tank offers fewer features, like a proprietary fabric blend or odor control, making it more affordable-so if you’re looking for high-tech gear, this may not be the move for you. This tank is an excellent option for runners on a budget who still want cooling comfort. The website boasts a “reflective logo” as a feature, but this is not enough for nighttime running safety. Nevertheless, this lightweight tank would still feel comfortable with a reflective vest over the top, if necessary.

Of all the tanks I tested, this was my second favorite and nearly $18 cheaper than my favorite. For runners on a budget, this is the way to go. It’s also worth noting that the Under Armour Fly-by Tank is only $25 and is also nice (just not as stretchy); the Brooks Distance tank is $30 and incredibly soft and comfortable, though slightly less cooling.


Other women's running shirts we tested

Brooks distance tank top for women with have a run day written on it

Brooks Distance Tank

Available sizes: L-XXL

Sleeve lengths available: T-shirt, tank

Fit: Athletic

Material: 88% recycled polyester, 12% TENCEL lyocell

This shirt was a close contender for Most Affordable, as its $30 price point is relatively low, and this shirt is so soft. The material is very comfortable and dries pretty quickly, even though it wasn't the lightest fabric we tested (the tank itself weighs 5.7 oz in medium). What kept me from reaching for it as often as the Saucony Stopwatch Singlet or the Flyout Trail tank was the fit 一 I didn’t love how high the neckline came up. I probably wouldn’t reach for this on the hottest days either 一 as soft as the fabric is, it doesn’t feel as cooling and airy as the other tanks.

BROOKS DISTANCE TANK


Janji Runterra Bio Boxy Tee GFX

Janji Runterra Bio Boxy Tee GFX

Available sizes: XS-XL

Fit: Boxy

Fabric: 70% Supima® cotton, 30% 37.5® tech polyester

The Runterera Bio Boxy Tee was a bit of a surprise for me–the design (by Elsa Zingilé ) is cute and the cropped hem provides pleasant airflow while running. However, the sleeves hang down a little longer than I’d prefer in a running tee. 

As I tested this shirt, I noticed I wanted to wear it after runs–it’s trendy and cooling, making it a good option for throwing on after taking off the sweaty shirt you just ran in. For what it’s worth, I also enjoyed wearing this shirt to the climbing gym. It’s a versatile and fun athletic shirt, just not my first choice for a running shirt.

JANJI RUNTERRA BIO BOXY TEE GFX


Janji Run All Day Tee

Janji Run All Day Tee

Available sizes: XS-XXL

Fit: regular to loose

Fabric: 100% polyester with HeiQ® Fresh treatment, UPF 25

The Janji Run All Day Tee worked wonderfully for cool to warm runs. The most comfortable experience with this shirt was on a 55 degree morning in the Colorado foothills.

While this shirt could certainly serve you well in warmer weather, the material doesn’t breathe as well as other shirts we tested–like the Nathan Dash Short Sleeve, the Patagonia Capilene, or the Oiselle Flyout material– especially in more humidity. However, the style and quality of this shirt still make it a solid option.


Nathan Qualifier

Nathan Qualifier Shirt

Available sizes: XS-XL

Sleeve lengths available: T-shirt, tank

Fit: Fitted 

Material: 45% recycled polyester, 45% polyester, 10% elastane

The Nathan Qualifier shirt looks more tailored than its 2.0 Dash Short Sleeve counterpart. It’s comfortable and looks nice, but I found it less light, cooling, and comfortable than the 2.0 Dash. This shirt is a good option for anyone who likes the tailored aesthetic but still wants the nice moisture-wicking material.

NATHAN QUALIFIER SHIRT


Rabbit EZ tee

Rabbit EZ Tee

Available sizes: XS-XL

Sleeve lengths available: T-shirt, long sleeve

Fit: Tailored fit

Material: 94% polyester, 6% spandex

I wanted to love this shirt. It is so soft and so cute. I wore it to work one day so I could work out right after, and I was so comfortable all day. The tight fit might be great for some people, but for me, it felt a little too warm for a summer run. However, if you’re looking for work-to-workout clothing, I can confirm this is a good option. It's a top-rated shirt at REI in both the short-sleeve and long-sleeve versions.

COMPARE PRICES OF THE RABBIT EZ TEE

Available sizes

Fit: Tailored

Fabric: 94% polyester, 6% spandex

What I didn’t love about the EZ Tee short sleeve is what works so well for the long sleeve. It’s soft, form-fitting material is cozy and warm for colder runs.

The color and fit is stylish too, making it a nice work-to-workout or casual wear-to-workout shirt.

I recently traveled around Europe for a month and had to pack light–a shirt that can double as casual wear and running top is a win.

Rabbit EZ Long Sleeve Option

Like with the short sleeve shirt, this is not ideal for really warm days as both the soft, warm material–94% polyester & 6% spandex–and tight fit is not the most cooling option.

As much as I enjoy this long-sleeve shirt, it just missed the cut of Best Long Sleeve Running Shirt simply because the Patagonia Capilene Cool Daily long sleeve is more versatile. Both shirts handle cold weather well, but the Capilene Cool is ideal for runs that warm up a little too, whereas the EZ Tee long sleeve is tighter and a bit less cooling.

RABBIT EZ TEE LONG SLEEVE


REI Swiftland Long Sleeve

REI Swiftland Long Sleeve

Available sizes: XS-3X

Fit: regular to loose

Fabric: Polyester (bluesign® approved)

The REI Swiftland long sleeve is a budget-friendly version of the Patagonia Capilene long sleeve. It’s made from lightweight and breathable SwiftTex™ polyester that wicks sweat and feels comfortable on cooler runs. Like the Patagonia Capilene, this shirt is produced in a Fair Trade Certified™ factory, and uses flat seams to prevent chafing. 

Despite its similarities to the Capilene, we felt this shirt didn’t quite reach the Patagonia shirt’s level of comfort and breathability, and the odor control feature of the Capilene is a noticeable difference while compared side-by-side. 

In any case, the REI Swiftland retails at $44.95 and is often on sale, making it a little bit more affordable than the Patagonia Capilene long sleeve, which retails at $49.

What we didn’t like: Rides up and can fit tight

The TenTree Inmotion Longline Bra was the only cropped tank we tested, so it felt unfair to compare this to the other shirts and tanks. It comes with a built-in bra, which I know some people love and others don’t. I needed to wear a bra in addition to the built-in when I ran in this, but it was nice to go braless in casual wear (or to the climbing gym). 

This tank fits tight, but the elastane added to the recycled polyester fabric gives some stretching room (which also might mean deodorant lines on the black crop after use, just FYI). The bottom will ride up, so if that makes you uncomfortable, I’d steer clear of this fit. If a little riding up doesn’t bother you, and you want to feel like a professional track athlete, this is an excellent addition to your workout wardrobe.

Under Armour Fly-by Tank

Available sizes: XS-XL

Sleeve lengths available: Tank

Fit: Streamlined Fit 

Material: 100% polyester

At $25, this tank is the most inexpensive running tank we tested and a runner-up for Most Affordable. On runs, we liked that the mesh-like material is lightweight and perforated (mesh-like) for increased breathability in hot weather. Overall, it is an excellent option for quality on a budget. The fit prevented it from winning the Most Affordable category 一 it’s a little tighter than the Saucony Stopwatch Singlet, and, in my opinion, the more comfortable fit is worth the extra $3.

Adidas Terrex Multi Primegreen Shirt

Available sizes: XS-XL

Sleeve lengths available: T-shirt, long-sleeve

Fit: Standard fit

Material: Recycled polyester

The Adidas Terrex Multi Primegreen shirt is made with recycled polyester for a light, moisture-absorbing material, with a weight of 5.5 oz for a medium t-shirt. We liked the lightweight material, dropped hem, and underarm gusset features on this shirt. While the material was great, I didn’t love the fit of the long-sleeve version of this shirt that we tested. It felt fairly tight, though some runners may like that coverage. With underarm gussets, there is increased airflow to make up for the increased coverage, so if more coverage is your priority and you still want cooling and moisture-absorbing features, this shirt is a good option.

TenTree InMotion Tank

Available sizes: XS-XXL

Fit: Athletic

Fabric: 88% REPREVE® Recycled Polyester, 12% TENCEL™ Lyocell

Similar in style and material to the Brooks Distance tank, the TenTree InMotion tank is made of soft, moisture-wicking material and transitions well from casual wear to workouts. We liked the soft material and the flattering cut as well the fact that it is made of recycled polyester.

The TenTree InMotion Tank fits a little looser at the neck than the Brooks tank. Our one issue with this tank is that it costs more than similar tanks. Personally, I reach for this one before the Distance tank we recommend because I like the neckline. Fut if the tighter neck of the Brooks doesn’t bother you, then I’d save the $10 and go with our tank pick.

buying advice

Fabric

The most common fabrics in quality running tops are durable polyester and nylon, which are breathable and stretchy. Spandex or elastane is used as a stretchy, lightweight fabric. Merino wool is another moisture-wicking fabric used often in running tops. You’ll also run into blends, including cotton, rayon, lyocell, or other trademarked blends. 

My favorite shirt as far as shirt material goes is the Nathan Qualifier, which uses mainly polyester and a little elastane. The polyester makes the shirt lightweight, hardy, and quick-drying-ideal for hot, sweaty outdoor activities-and the elastane adds some stretch to the shirt, making it comfortable and easy to pull up to wipe sweat.

I would argue most people don’t need to be too concerned with the exact blend of materials as long as it’s any combination of lightweight, durable, breathable, sweat-wicking, or water-resistant. You want to steer away from majority cotton shirts when investing money in your workout wardrobe, as it traps water and feels weighted.

The Nathan Dash 2.0 running shirt uses a fabric with just the right amount of stretch.

Fabric Weight

When working out in the heat, the lighter the fabric, the better. Often this comes at a cost, but if you can invest in lightweight shirts, you’ll be thanking yourself during your toasty summer workouts. Most of the tops I tested weighed around 3 ounces, which felt right for me.

Breathability

If you are running in the heat or humidity, you need clothes that allow some airflow. Nylon and polyester fabrics are breathable, looser-fit shirts tend to feel more breathable, and tops with any mesh allow for that airflow that’s so desirable on steamy days.

Moisture-wicking

The synthetic blends mentioned above (polyester, nylon, etc.) are considered moisture-wicking and ideal for outdoor activities. Wool is also moisture-wicking, and while I don’t prefer lightweight wool in the summer, many outdoor brands effectively use merino wool in their running shirts. Those who prefer wool enjoy the fabric’s ability to wick out the moisture, so the shirt remains dry to the touch. While wool isn’t my fabric of choice, it is an excellent option for many.

It’s important to note that moisture-wicking is an important quality in running gear regardless of the weather. Even in cold climates, runners are likely to sweat. Sweat that isn’t wicked off the body-that collects between the fabric and the skin-is undesirable regardless of the weather and can worsen chafing.

Comparing the fit of the Oiselle Flyout Racerback (top) and Oiselle Flyout Trail Tank (bottom).

Fit

You'll see many terms if you look into the various “fits” of running shirts. I’ve always thought of them as “tighter” and “looser,” so let’s dive into the options from that framework. On the tighter-fitting end, you’ll see terms like “tailored fit,” “slim fit,” “body skimming fit,” and “fitted.” You have “standard fit” or “athletic fit" on the loose end.

These terms are not an exhaustive list, and frankly, knowing these terms doesn’t necessarily help any better than simply looking at photos of the shirts or trying them on yourself. And there is no “best” fit–it depends on your preference and what feels right to you. I prefer the standard fit in women’s shirts-loose, light, airy, perfection.

For tanks, you’ll see a large variety of fits. A couple of the more common ones include “athletic” fits, like the Brooks Distance tank, and “racerback” tanks, like the North Face Flight Weightless tank. 

Example of flatlock seams on a tshirt

Close up of flatlock style seams on one of the running shirts we tested.

Flatlock seams

Flatlock seams-a method of stitching together fabric without overlapping the materials-are a gift from the running goddesses that help prevent chafing. Common chafing trouble areas are at the armpits and wherever a hydration pack might rub, so flatlock seams should be a high priority if you are investing in quality running clothing.

Sun protection

Since moving to the high-altitude city of Denver, Colorado, I’ve been careful about protecting my skin from UV rays. Sunscreen is a habit I wish I would have been better about earlier in life. Shirts with sun protection are a good option for folks who want to add another layer of protection to our body’s largest and most exposed organ. 

Like with underarm gussets, this was a feature I knew very little of in my early years as a runner, so I can’t speak from years of experience on this, but if UV protection is important to you, this feature should be on your radar. And as a bonus, you won’t have to worry about sweating it off as you might with sunscreen!

Reflective elements

While summer months offer more daylight, sometimes we beat the heat with early morning or late evening runs. Reflective clothing offers peace of mind while you’re on the roads. Running shirts with reflective elements are especially lovely if you do not want to add a layer, especially on those already hot or humid mornings.

Underarm gussets

Underarm gussets are sometimes added to running shirts for breathability and airflow. If you are anything like me (you sweat, a lot), you may appreciate this feature. If I had encountered more shirts with underarm gussets in my younger years, I’d have been more inclined to run in shirts and not solely tanks. That is to say--this is a welcome feature for someone like me.

Odor control

Admittedly, odor control was never high on my priority list in my younger years (though maybe it should have been). To be fair, it wasn’t until recent years that I learned this was even a feature of some shirts. Some shirts offer this feature, like the Patagonia Capilene Cool Daily, to prevent smelly bacterial growth from causing bad smells. I didn’t particularly notice this feature, but it could be something that proves its worth over time.

Hanging loops make it easier to safely hang dry performance apparel made of delicate lightweight fabric without causing damage to the garment.

Hanging loop

Do you foresee wanting to hang your shirt on hooks, like in lockers? If so, the hanging loop is for you. It’s a fun feature I’ll admit I never noticed until recently, which tells you how little I’ve personally ever needed it.

The main advantage of hanging loops is to safely hang dry performance apparel made of delicate, lightweight fabric without causing damage to the garment. It also makes it easier to hang wet, smelly shirts so they can dry more quickly. This prevents the growth of odor-causing bacteria.

Neckline

Common neckline styles include crewneck, scoop neck, and v-neck. The gentle curve of the crewneck is perhaps the most common. V-necks come to a sharper point in the front, and scoop necks are similar to crewnecks and tend to hang a little looser. 

Most running shirts and tanks — like all the ones we tested — will have a crewneck neckline that falls a few inches below the neck, which is ideal for most people as it doesn’t fit too uncomfortably close to the neck. Occasionally, shirts and tanks will have higher necklines for those looking to minimize sun exposure. Some runners may prefer a lower neckline for comfort, but others may choose a higher one for added coverage.

Hem-length

Hem-length has always seemed to me to be a style preference, but loose cropped tops can be great for breathability if it’s a style you’re comfortable wearing.

Tighter cropped tops, in my opinion, create the mental effect of channeling one’s inner professional track athlete and have always been a style of choice for big workouts and races. 

DROPPED HEM

Dropped hem running shirts are the ones that come up a little higher on the sides and a little lower in the front and back (or sometimes in just the back, commonly seen with tanks). Generally, this is a style choice that some-especially folks with longer torsos–may prefer if they wish to prevent their lower back from being exposed while bending over. I recommend picking whatever style makes you feel like your best self. Your running clothes are your power suit, and the mental impact they have on you will carry you just as far (if not farther) than the technology in the fabric and fit.

Durability

Running shirts are made of technical lightweight fabrics that are prone to snags and pilling. The lighter the shirt, the more likely it may see wear over time. It’s a trade-off, but some lightweight shirts are better at staying in good condition over the long haul.

The best running shirt for you is the one that will leave you feeling comfortable and confident while exerting yourself and immediately after you’ve stopped moving in cooler conditions.

How to choose the running shirt for you

What kind of running will you be doing?

The amount you should invest in your running wardrobe depends on how often and far you run. As someone who runs less than before (curse my arthritic hip!), my running clothes last longer now, so I don’t need to spend as much. 

Will you be running with a hydration pack? If so, you may want to consider clothing that covers the skin where the pack will be (I learned this lesson the hard way, the consequences of which included some of the most painful post-run showers of my life and loud curses every time a gentle breeze brushed my raw skin).

Two examples of reflective elements on a teal running tank top

Saucony boasts “reflective elements,” which is nice but shouldn’t be a selling feature as this isn’t enough for safety.

Will you be running in the dark?

Visibility is essential if you know you’ll be running in the dark. If your gear doesn’t already have reflective material, you’ll want to wear reflective gear over your clothing. Some shirts boast reflective elements — like the Saucony Stopwatch Singlet — but they are not enough for safety. You should prioritize other elements over this investment, like quality material, a comfortable fit, moisture-wicking, etc. I would not consider “reflective elements” a selling point unless a significant portion of the shirt is reflective. You can always buy the shirt because it fits your other needs and add reflective gear and/or lights over it when you run in the dark.

On the left is an example of a raglan sleeve, and on the right is a set-in sleeve.

How much arm coverage do you want?

Whether you choose tanks versus short sleeve shirts versus long sleeve shirts and the amount of arm coverage depends on several factors. These factors include: 

  • Are you running in hot or cold weather?

  • Are you running with a hydration pack, running vest, or reflective gear?

  • What length makes you feel most comfortable?

  • Do you like the appearance of the shirt?

  • What's the atmosphere of the workout space?

When it comes to atmosphere, when I coached high schoolers, I wore shirts rather than tanks to practice because it felt more “professional” to me. 

If you want more arm coverage, you’ll want to check the hems and the fit at the armpits, as that is a common source of chafing. Set-in sleeves-with seams around the arm-tend to be more tailored and tighter than raglan sleeves, which have seams from the neck to the armpit. Raglan sleeves are often a better option for people who chafe at the armpits, though it can also depend on how tight the material is or how long the sleeves are.

For each of our winners, we include whether they are available as a tank top, short sleeve, or long sleeve.

How much neck coverage do you want?

Shirts and tanks with tighter necks are, to me, uncomfortable. This aspect of shirt-buying seems like a personal preference, so I won’t say tighter necks are bad. However, looser neck holes are less constricting and–if you have the same habit I do--better for wiping sweat off the lower half of your face.

On the other hand, higher neck coverage may be for you if you prefer more coverage (for sun protection, your hydration pack, or simple comfort).

Do you want a longer torso running top or a more cropped style?

In an informal poll of my Instagram followers and friends, I found the whole long torso versus cropped style to be divisive. Half of my followers wanted the biggest, baggiest shirts they could find, and the other half preferred the least amount of material possible. 

Longer torso shirts are great for folks with-get this-longer torsos and anyone who appreciates greater coverage. 

Loose cropped shirts encourage greater airflow and allow you to channel your inner Tommy Rivs, and tight cropped shirts might make you feel like a professional track athlete. My advice here might make me sound like a broken record, but wear what makes you feel comfortable and powerful.

Do you want a phone pocket?

You’d be hard-pressed to find a bigger fan of pockets than this gal right here, but I’ll admit, this isn’t a factor I’ve ever considered in shirts or tanks. I like my shirts to fit light and loose, and a phone would only weigh the material down. I look to shorts, sports bras, and belts or packs to store my phone. I didn’t find many shirts that offered pockets on this search. But hey-if you find a shirt with a phone pocket and love it, I say go for it.

The Patagonia Capilene running shirt we tested is made of recycled material in a Fair Trade sewn factory. For many runners, knowing how it is made may be an important feature in choosing what shirt to get.

What features do you want?

Consider the following when shopping for running clothes: 

  • What time of day will you be running? Will it be light or dark?

  • What weather extremes will you be experiencing? Extreme heat? High UV? Heavy rain?

  • Will you be running with a hydration pack?

  • What styles do you enjoy? Will you be more comfortable in looser or more fitted shirts? Will you want shirts that hang lower or cropped tops?

  • Do you tend to have chafing issues, especially at the armpits? 

  • Do you want a shirt made of recycled material or with eco-friendly and socially good manufacturing practices?

Answering these questions will help you prioritize the materials, coverage, and fit that suit you.

How much do you want to spend?

Listen, there is no judgment here. I spent most of my running career spending very little;  I milked free running gear or found discounted running clothes here and there. I had very little income and needed to budget more for marathon training food that complied with my laundry list of food intolerances.

Even with disposable income, I waited for sales and shed a tear at the cost of a simple sports bra or tank. But I also recognize the benefit of investing in quality clothing. I’m not saying you need to drop hundreds on an entire wardrobe of running clothes (though, if that’s your thing, you do you!). If you’re reading this article, I am saying you’re already considering investing. And in that case–how much money is the sweet spot to spend?

The average cost of my favorite shirts and tanks was about $50 MSRP. The Brooks Distance tank–which wasn’t my favorite but for which I had few complaints-is $30. Most local running stores offer rewards programs (often, if you purchase your running shoe, you’ve already earned rewards), so if you play your cards right, you may just get lucky.

Most of my favorite running clothes–the ones I wear every laundry cycle and have lasted an embarrassingly long number of years–were purchased on sale or with rewards or dividends (this is my unofficial plug for REI, I guess). Sale-hunting, if you have the energy and time for it, is a tactic my frugal soul recommends. Check out Treeline Review's Deals Page for pre-scanned discounts on gear that we recommend. 

Spending money on your running wardrobe is an investment in yourself and your hobby or passion. Quality clothing should last longer and make your workouts more enjoyable. However, how much you invest is totally up to you and your circumstances. Personally, past $50, certain features become not worth the price. For example, the Ibex Weightless Wool shirt is nice but not worth $88 to me. As much as I love the Oiselle Flyout tank, $45 is a lot more than the Saucony Stopwatch tank at $28, which I liked almost as much. Odor control is a cool-sounding feature, but I would never pay more for a shirt for that feature alone.


A woman standing on a dirt road in the mountains wearing a running tshirt

A women’s running shirt should fit in a way that allows you to perform in the weather you’ll be facing as well as works well with hydration vests, reflective vests, or other running gear that you use.

FAQ

How should a women's running shirt fit?

Other than a few basic principles, the right fit depends on the person. Running shirts should feel comfortable (you may as well make yourself as comfortable as possible while you’re making yourself uncomfortable, right?).

I’ve had teammates and athletes who ran in the loosest shirts they could find (a la Courtney Dauwalter), some who prefer a more fitted shirt, some outliers who like the tight spandex, and some who prefer no shirts at all (sports bras, people, sports bras). 

The goal is to find what works for you. Someone who runs early in the morning in a big city may prioritize a more fitted shirt that works with a reflective vest, whereas someone running on humid neighborhood roads after work may prefer a looser, wicking shirt. The point is, there’s no one-size-fits-all answer. Find what works for you, and don’t worry about what is “right” or “wrong” in someone else's eyes. 

Chafing from running shirts is most likely to happen in the armpits and along seams. The Nathan Dash 2.0 has flatlock seams that reduce rubbing and underarm gussets can be helpful, too.

Chafing from running shirts is most likely to happen in the armpits and along seams. The Nathan Dash 2.0 has flatlock seams that reduce rubbing and underarm gussets can be helpful, too. And never underestimate Body Glide!

How do I prevent chafing while on a long run?

While I’ve found simple ways to alleviate chafing, I’ve always struggled to avoid the week or so of chafing that happens between seasons. When do you switch from winter clothes to summer and vice versa? Every season my body needs to adjust to the new materials in new places. That’s when I lather on the Body Glide or vaseline. But if we’re talking about limiting chafing from a running top perspective, let's look at how to prevent it from happening generally.

First, flatlock hems are your friend, as they do not rub against your skin as much. Underarm gussets can be helpful too, or tanks with underarms that don’t rub where your arms might meet your upper body while you run. It might require testing of your own to find the right fit, as each body is different, but quality material matters. Cotton holds moisture and can worsen chafing, so stick to the synthetics or merino wool.

How are women's running shirts different than men's running shirts?

Treeline Review recognizes that there are more genders than just men and women but works within the reality that gear sizes and shapes are categorized this way. Choose the shirt that best fits and feels comfortable to your body, regardless of how the brand may have labeled the item. 

Sometimes marketing is simply gendered without significant differences beyond the color, unfortunately. Remember that, above all, you should choose which shirt fits your body regardless of how you’re targeted as a consumer. You know yourself best.

A pile of just some of the running shirts we tested side-by-side.

How we tested

It’s summer in Denver, so the mornings are cool, and the afternoons are nearly 100 degrees. I ran in the late afternoon/early evening and morning to test these shirts. I wanted to see how they handled sun and heat, as that is when comfort and cooling features are most important.

Because I was recently diagnosed with hip arthritis and can’t commit to the long miles I once cherished, the shirts were tested over many short runs that also included a lot of walking in the heat of the day to work up a sweat.

I worked out in these shirts on the roads and the trails, in the heat, and on cool mornings. While running, I paid attention to how the clothing felt on my skin, what felt most comfortable once sweaty, what dried fastest, what felt coolest or offered the best air circulation, and what had a good stretch. I considered how a running shirt shouldn’t be a distraction; if it’s doing its job, you likely won’t notice it.

Are trail running shirts the same as road runners?

I’ve noticed a trend of companies marketing shirts as “trail” shirts, and as someone who’s spent a lot of time on both sides of that divide, I wondered what a trail runner would need that a road running top couldn’t provide.

In more humid environments, trail runners may have a greater need for moisture-wicking or a lighter material, though, in my opinion, I’d like that for road running, too. Perhaps the essential quality for a trail running shirt is a material and fit that prevents chafing while wearing a hydration pack.
