Salomon is a big name in trail running, and the Salomon Adv Skin 12 vest lives up to it.
We’ve been testing this hydration vest since 2020 and have tested the newest version (released in 2025) nearly since it was released three months ago.
This Salomon vest shines in its versatility precisely because of its easy fit adjustments. This vest accommodates changes in your load weight and even body shape. We also like how it handles several shapes of hydration flasks, water filters, and bladders.
We’re confident this is the most comfortable running hydration vest we’ve tested (and we've tested a lot for our Best Running Hydration Vest guide, where it won Best Overall Running Hydration Vest).

With a storage capacity of 12L, it’s in the middle of the capacity range among most vests. The Salomon Adv Skin carries all 12L of gear just as well as when the pack is nearly empty.
This Salomon Vest has pockets everywhere, and though it takes some practice with the vest to figure out where your items should live, once you do, it’s clear the Salomon Adv Skin is made for the movement of running and all of the things that we carry with us to get far out there.

Best For
The Salomon Advanced Skin 12L running vest is appropriate for any running involving extra gear, except for non-racing overnight runs when some level of sleep insulation and shelter is required. That’s the case whether you’re heading out for short or long races and daily runs on trails in the mountains, foothills near town, or dirt roads. We liked it for trail running and endurance races. If you like to road run and carry an extra layer, water, bars and gels, or other items along, the Advanced Skin 12 is equally suitable.
Some runners may prefer running belts on shorter outings for increased back breathability. Some runners may even be satisfied with stuffing items in a pair of running shorts.
But many folks find running belts chafe or bounce excessively, and shorts pockets are too small or sag and bounce with too much weight. That's why we recommend the sleek Salomon Adv Skin 12, which moves with you to feel more comfortable during a trail run. That's the reason it's the overall winner in our guide to the Best Hydration Packs.

How We Tested
We’ve tested the various iterations of the Salomon Adv Skin 12 running vest on all across the U.S. Photo by Trey French.
We've owned and extensively run in versions of the Salomon Adv Skin 12 running vest since February 2020. Since the newest model was released early in 2025, we’ve run in it almost exclusively for the past three months.
It has spent most of its life on trails in the rolling green hills and mountains of Massachusetts, including the New England Trail, with additional time spent in surrounding Northeast states, including long runs in the White Mountains of New Hampshire on the Appalachian Trail and on the Pemi Loop. We took previous versions on years of running in the high country of Colorado in the Sawatch and Sangre de Cristo ranges, Tennessee, Utah, and California.
We typically take it on runs longer than 2 hours, especially if there’s no access to water, and on shorter runs when the weather is changing and unpredictable.
We also have a women's tester who carries the women’s version of the vest on every run, even if it’s just for her phone and keys.
Collectively, we’ve carried it up long trails and down long, hot roads back into town. We’ve taken it across expansive mountain ridgelines in the White Mountains.
It’s seen on- and off-trail use. It's there with us for long runs and shorter training trips.
It has carried our water bladders and flasks, sandwiches and snacks, phone, rain jackets, insulation layers, sunglasses, batteries, headlamp, and emergency beacon on remote all-day outings out of service.
We’ve rarely washed it, using it repeatedly and only rinsing it when the salt marks build up. We’ve forgotten it closed up in bins after days of long summer runs, scrambles, and hikes, and buried in a pile of other running gear.
We’ve scraped it on rocks, fallen on trails wearing it, and thrown it haphazardly on the ground and in the back of the truck. We’ve maltreated the thing, and despite its lightweight build, it keeps going without issue.
Salomon updated this running vest for 2023 and 2025. This review reflects our experience with both the newer and older models, what has changed, and what improvements we’ve seen.
What We Liked
Carries well empty or full
Includes 2 x 500ml quality hydrations flasks
2L hydration bladder compatible rear reservoir with bladder hang hook
“Adv Skin” fabric creates a supreme fit around the ribs and chest
Stretchy shoulder strap for managing bounce
Functional pockets galore (though less than the previous model)
Uses a unique Quicklink bungee system instead of the standard sternum strap. The Quicklink allows some stretch, and more evenly contours to different body types.
Improved zippers (newest version)
Some affordable replaceable hardware is available
Torso length sits high enough for back ventilation but not too high as to be unreachable
Available in a smaller size for those looking to prioritize pack weight or small loads
Price is fair, and the vest is on sale periodically
Features

Adjustable Fit and Comfort
Ultimately, what we think makes the Salomon Advanced Skin 12 stand out is how well it fits and secures a load, whether it’s almost empty or at capacity, along with its dialed fitting system. The stretchy shoulder strap fabric creates a minor suspension so that the vest stretches through the impacts of the running stride, but not so much that it feels sloppy.
The Salomon “Adv Skin” mesh fabric balances breathability, durability, and stretch. This vest won our award for best running hydration vest because it is notably the most comfortable. Of the packs we tested, it conforms the best around the ribs, where a lot of oddly shaped gear (food, headlamps, and layers) usually ends up. This discomfort is a common flaw in the running pack category. The Salomon Adv Skin's mesh kept everything in place so we could run comfortably without feeling our gear.
Salomon uses a few adjustable stretch “shock cords” and plastic hardware to help dial in the fit around these curvy areas in conjunction with the Adv Skin mesh. Specifically, one fit detail that we liked is the bungee style “Quicklink” style of adjusting the hydration vest up front.

Found in all Salomon running vests, this criss-cross bungee allows for excellent stretch and better conforms to various body types compared to many vests—which use the more common dual sternum strap. The chest strap on this vest—and also found on any other Salomon products —keeps everything in place better.
The newest version changed the shock cord used for the Quicklink set and all elastic connections, including holding hydration flasks in place. The cord is thicker and substantially less stretchy than previous models.
The most substantial impact is that the vest now fits tighter around the chest and ribs. With this change, sizing up is now recommended. The new cord also makes it more difficult to remove and replace hydration flasks, though it does address the existing durability issue of the flasks’ elastic cord no longer holding bottles securely due to stretching.
Additionally, Salomon offers a replacement Quicklink set to replace a worn one. While we haven’t broken ours, it’s a low gauge shock cord system with small plastic pieces that could break. Knowing that we can replace it for $8 gives us peace of mind. Otherwise, we’d have to DIY fix it or purchase a new vest.
It might be a good idea to add a replacement Quicklink system to your cart when purchasing. I keep one inside my hydration pack just in case. It’s low volume and low weight. Worst case scenario if you didn’t carry it? Tie any broken cord into a knot to get you home.
Hydration System
The Salomon Adv Skin 12 excels using flasks and a bladder with a 2L capacity (up from 1.5L in the old version) and a hang loop in the rear closure.
We love that the Salomon Adv Skin series comes with 2 x 500ml hydration flasks. For those getting into running, paying $20-30 per soft flask after investing money into a running vest is a drag. We're big fans of soft flasks over traditional bottles, and even recommend them in our Best Gifts for Runners guide. It's nice that with the Adv Skin they are included, and we find the quality of these flasks to be great.
For those who like bladders, the Adv Skin 12 has an insulation space for a 2L bladder (but you have to provide your own bladder). The Skin 12 no longer includes an insulation sleeve to keep the bladder cool.
We think hydration flasks have several advantages over using a bladder for some people. One is that they’re more simple to clean and get dry.
Secondly, if one of them gets a hole, one is still functional to get you through the day.
Speaking of multiples, you can keep water in one and some liquid nutrition, such as Tailwind or Skratch powders, in the other. The multiple bottle strategy also works for electrolytes.
You can carry more water in a bladder, however, but we’ve had no trouble using flasks with lockable nozzles for extra capacity in the rear back pocket with mesh pocket of the Adv Skin 12 as well.
Often, if we need more than a liter up front, we’ll pack a full Befree water filter bottle in the back or a lockable nozzle Ultimate Direction 500ml Body Bottle flask. That said, using a bladder can be a convenient way to keep a lot of water readily available near your mouth to encourage drinking throughout the day. Either way, the Adv Skin 12 has no problem accommodating either method, or using both together!
Material: Breathability and Water-Resistance
The primary fabric that sits next to your base layer running shirt is a weave of large, open-hole mesh fabric commonly referred to as “spacer mesh.” This mesh helps create airflow between your body to aid in transporting moisture away from your body and keeping you cool. The 2025 version incorporates a softer but less stretchy fabric on the inside of the vest’s sides and front.
By nature, any fabric against your back will inherently run warmer than wearing no vest. The spacer mesh aims to simulate this feel as much as possible–while also allowing you to carry the gear you need to get out in beautiful scenery.
The Salomon Adv Skin 12 vest doesn’t sit so low that it overheats your lower back. While it could potentially have more breathability if it had high-rise torso length, we think it sits just right. It's still easy to reach for items behind you, whereas higher-rise torso lengths on vests make it nearly impossible to get your gear without taking the pack off.
When it comes to water resistance, there really is very little, and we don’t fault the vest for this. Water resistance isn’t standard on these running vests styles, especially when it comes to such stretchy fabric as is found on the Adv Skin. Other than DWR applications, waterproofness may come at the expense of more static fabrics with tighter weaves like Silnylon or polyesters found on waterproof backpacks and rain jackets. Salomon does use polyester fabric for the back panel separating the vest from the rear zippered compartment that offers cursory water resistance, though it doesn’t hold up to more than light sweat on a shorter run.
If you need to waterproof anything in your pack, we’d recommend using the running pack equivalent of a backpacking pack liner. This waterproofing might be a heavy-duty Ziploc bag, a stuff sack or dry bag, or a small plastic bag mimicking a larger pack liner.
Pockets and Gear Accessibility

Holy pockets. The Salomon Adv Skin 12 has no shortage of pockets, though the 2025 version uses a less stretchy material which reduces capacity and impacts comfort. Here we go:
1 internal bladder space. This large pocket is in the rear of the vest that sits closest to your body, or “center of mass,” to keep the bounce down. We found that the bounce is minimal with a 2L bladder in this pocket, especially with the dialed-in fitting adjustment for the rear pockets. One upgrade of the 2025 version is that this space now can hold 2L rather than the 1.5L of previous versions.
2 front stretch zipped pockets. We like to store small, easily lost items like sunscreen, chapstick, our phone (they’re pretty big pockets, though they’ve gotten a lot tighter on the latest version), and maybe some small nutrition items like energy chews or gels or Tailwind packets. These also work well for putting your wallet and keys on one side. We designate those zippered pockets as a security pocket that only gets opened when starting and finishing our run back at the car.
2 x 500ml hydration pockets. Each soft flask pocket fits various 500ml sizes (long and slim, wider, etc.) and has a toggle to wrap around the top of the flask to secure it from falling into the pocket after clearing some water from the flask. This is a simple function that we wish all running vests shipped with, even if they were removable.
2 shoulder stretch pockets. These are layered over the water bottle pockets. While they don’t zipper, they now overlap so small items can be securely tucked inside. In past versions, items could easily fall out. We like to keep trash, food, and small compressible items here, like a Garmin inReach Mini 2, gloves, or a warm hat.
1 x large rear tunnel pocket. This pocket is accessible with either the left or right hand and runs across the lower back of the vest. While this pocket used to be attached to the front stretch pockets for one continuous pocket, it now starts around the base of the ribs as its own stand-alone pocket. It relies on tension to hold items in, and we’ve never lost anything using it. That said, it’s good to take the time to check the ground after stashing or removing a running jacket or other pieces of gear in there because it’s possible to push or pull something out.
Volume
Our model expands with storage up to 12L. We’ve put a lot of stuff in there and filled it to the brim. While past versions use a very stretchy fabric for the rear compartment that expanded past 12L, the newest version uses a mix of elastic fabric on the sides and stiff fabric for the center panel. While this addresses any possible sagging over time, now items that would have stretched the bag in the past are more likely to poke you in the back. This also means that the carrying capacity of the zippered compartment is reduced and less comfortable, compared with past versions.
The bottom pocket is the best option for storing a jacket on the new version of the Salomon Adv Skin 12. The pass-through “tunnel pocket” is a typical design feature on running vests. The one on the Adv Skin 12 is easier to reach than many other vests but is still not the easiest shoulder motion. Photo by Kris LaRosa.
Salomon offers the Adv Skin vest in a 5L version as well. Our reviewer wanted a general do-it-all vest, and the 12L checked those boxes for the storage needed for big days and carries. Because it condenses down so well, it handles lower volume days, too. If you have a specific need for the Salomon Adv Skin and don’t anticipate ever using more than 8L, we can’t find a reason to advise against it.
Weight
The latest version of Salomon Adv, 12 in a unisex medium, weighs 247 grams or roughly 8.7 oz, down quite a bit from last version.oz. We’d say this is perfectly acceptable and lighter than we would anticipate without knowing, given all the pockets and toggles on the vest. Our previous version, sized at a men’s medium, made for a 37.5”-40” chest, measures 293 grams / 10.3oz. Though this isn’t a delicate piece of gear, it might be best served by someone who treats it better than we do!
Durability
Durability is another area where the Adv Skin 12 shines. Constructed from high-quality materials and reinforced stitching, it has lasted hundreds of miles over rugged terrain and repeated use with limited signs of wear and tear.
Past versions’ most common failure point for one of our long-term testers (who is a salty sweater) was the front pockets’ zippers. The front zippers malfunctioned within ~9 months of regular use, even when washed after each run and with the use of zipper cleaner. Salomon has a 2-year warranty for running vests and they quickly replaced our tester’s broken vests. This version’s zippers have been upgraded to a heavier duty zipper (from #3 to #5). In our testing so far, these zippers have shown no signs of wear or catching on built-up sweat (which past zippers have shown early on). We’re very hopeful this version’s zippers will offer better longevity for salty runners.
Additionally, while the thicker, less elastic shock cord to hold the hydration flasks makes it harder to remove and add flasks, it does address the previous version’s observed long-term durability issue of bottles sliding down into the vest due to the elastic stretching over time.

Sizes available
In men’s/unisex, it’s available in XS-XL for chests measuring 33”-46”.
For the women’s model, it’s offered in an XXS-L for chests measuring 32”-43”.
It’s not the most inclusive sizing out there, and we’d love to see the vest offered in a wider range.
Sustainability and Ethical Business Notes
Salomon is big for a running (plus other sports) company, with 1,650 employees reported, with offices in Europe, North America, Asia, and South America. Salomon uses its size to enact positive change in various fields, not limited to the following: engage in local community action, climate issues related to products, equity in gender and race employment, fair labor practice in their immediate company, as well as their supply chain. They offer a long list of concrete goals for public view in the coming years.
What we love about their delivery of this information is that they couch it all under sustainability. Not limited to the environment, but the sustainability of the workplace, supply chain, local communities, and making the sport more inclusive. You can start your journey reading about Salomon’s ethics here.
What Could Be Better
The previous version of the Quicklink adjustment system used a thinner elastic. Photo by Justin Walker
We’d love to see the vest offered in larger sizes across both men’s and women’s versions.
Relatedly, with the use of less elastic fabric and cord, we would have liked to see longer elastic cord for the vest closure’s Quicklink system. As currently designed, past vest sizing experience is now inaccurate, requiring a size up for most users. Additionally, our users really enjoyed the rain shell/windbreaker pocket built into the top of the 2023 version of the vest– we would love to see this added back in future models.
On some older versions, there were complaints of some broken hardware that seems to have since been resolved. Zipper durability was a past issue for one of our (salty) testers, and we’re happy to see Salomon responding to some of the feedback they’re getting and upgrading the vest’s zippers. Salomon also now offers replacement parts for broken Quicklink systems, which is more sustainable than buying a new vest.
Some may be shocked at the price, but it is average for the industry and not incredibly steep.

2025 Updates
The newest version of the Adv Skin 12 had some major changes, compared with years past. Many of these changes seem small, but we found they have changed the user experience and performance in the field. You can still find the old version of the Adv Skin 12 in a few retailers.

Pockets and Gear Accessibility
The trash pocket and extra back panel pocket were removed. We miss them and wish they were still there!
The bladder space no longer includes an insulating sleeve. However, the bladder space now accommodates a 2L bladder, an upgrade from the past 1.5L allowance.
The shoulder pockets now overlap to more securely hold items; these used to be open and sometimes lead to items falling out. The tunnel pocket that used to wrap from front all the way around back is now disconnected; there are no side pockets anymore.
The vest’s 3 zippers (front pockets, rear bag) were upgraded to more robust #5 zippers, when #3 zippers were used in the past. So far, we have high hopes for these better zippers!
Adjustable Fit and Comfort
The previous version of the Salomon Adv 12 running vest in Salida, CO used a thinner elastic shock cord. Photo by Justin Walker
The vest closure's Quicklink system was updated to a thicker but much less elastic shock cord; in the field, this restricts sizing and increases compression of the user’s chest.
Most people will need to size up from their expected size.
The same shock cord is now used for compression of the rear compartment, securing hydration flasks, and the cinch cords around the bottom hem.
The lack of elastic makes it more difficult to remove and replace hydration flasks, while also addressing the past versions’ durability issue with the same elastic.
One benefit is that the change to the shock cord makes carrying running poles on the lower back a bit easier, since there is less elasticity and therefore less bounce.
Material

Multiple portions of the vest had changes to texture and elastic of the fabric. The inner vest front and sides are now a smoother texture, meant to decrease possible chafing.
The rear zippered compartment now consists of a mix of elastic and stiff fabric (rather than the entirely elastic fabric of the past version), reducing the volume and flexibility of the pack.
Similarly, the front zippered pockets are less elastic now, reducing the pockets' ability to comfortably hold a phone–our tester's Samsung S20 cellphone protrudes from the pocket, increasing the risk of chafing if the pack's front pockets are loaded up.
More Durable Zippers
The newest version of the Adv Skin 12 Set uses more durable zippers (upgraded to #5 from #3) and toggles from YKK, which is THE zipper brand. YKK and the stronger zippers of this model are upgrades for reliability, longevity, and ease of use. You'll find the stronger YKK zippers on the front zippered pockets and the rear zippered compartment.
Other Capacities Available:
Salomon Adv Skin 5
Hydration included? Yes, 2 bottles
Weight: 8.04 oz
Sizes available: 32 - 45" chest
Number of external pockets: 7+ main pockets
If you typically stick close to home or the trailhead, run short races, and don’t intend to carry lots of water or clothing, consider going for the Adv Skin 5. You’ll save a little weight and volume.
Ultimately, we don’t regret going with the 12L for its added versatility. Other than size, the 12 and 5L are mostly the same, one significant difference being that the top pocket has an open elastic closure instead of a zipper.

Other Running Hydration Vests to Consider
Salomon Sense Pro 6
Hydration included? Yes, 2 bottles
Weight: 5.1 oz
Sizes available: 30.9 - 44.2" chest
Number of external pockets: 9+ main pockets
The Sense Pro 5 is a more race-oriented vest with fewer adjustments, zippers, and doodads.
It has a more streamlined design but retains the same Quicklink system up front and a similar amount of stretch.
It’s paired down to a more race-specific use, which means it’s a little quicker on the transition from dumping and reloading, but may lose some of the versatility of the Advanced Skin models.

Salomon Active Skin 8
Hydration included? Yes, 2 bottles
Weight: 7.4 oz
Sizes available: 30.9 - 44.2" chest
Number of external pockets: 9+ main pockets
Salomon describes the Active Skin 8 as a stepping stone into running hydration. What we think Salomon is getting at here is its affordability at $115, which includes identical 2 x 500ml hydration flasks.
We think the Salomon Active Skin 8 is an excellent deal for those looking to primarily carry the vest for food and hydration, plus a low-volume layer or two. It has fewer pockets and volume, but it keeps the same Quicklink system up front, comfortable mesh. As a bonus, our tester reports it has a faster drying time, which could be better for those running primarily in humid environments.

You can sometimes find more options when purchasing directly from the retailer. Purchasing directly from the retailer can make it easier if you need to make a warranty return, such as if there is a defect.
Advice on where to buy
In our testing, we found that most people will want to size up with the updated Salomon Adv Skin 12, especially compared to previous models.
That's why we recommend purchasing from a place with easy or free returns like REI. Trying on hydration vests is an important way to get the sizing right, especially to ensure comfort when it is (hopefully not) bouncing around during your run. If your funds allow, you can buy two sizes and easily return one. Additionally, check reviews to see whether other users recommend sizing up or down.
