Running Hydration Vests Comparison Chart

Best Running Hydration Vest Overall

Patagonia Slope Runner Vest

Weight:6.9 oz with flasksSizing:XS-LHydration:Comes with two 500 mL (17 oz) soft flasksCapacity:4 L

Pros and Cons+ Water resistant+ Great pass-through pocket– Lack of large main compartment limits carrying capacity

The Slope Runner Vest has been our choice for best running hydration vest for several years, and it’s the pack we’d choose if we could only have one, thanks to its comfort, convenience, and versatility. We love its airy, lightweight materials with a Durable Water Repellent (DWR) finish that repels precipitation. We also appreciate that it breathes Patagonia ethos: it’s Fair Trade-Certified and made without PFAS/man-made chemicals.

The running vest carries ample fluids securely and conveniently: Two included 500-milliliter flasks sit comfortably in deep mesh chest pockets, and a simple clip effectively holds a hydration bladder, when added. Other storage is equally well-designed. Six stretchy mesh pockets on the chest and waist straps are easy to access mid-run. The pass-through pocket on the back proved a great place to shove a layer and which can then be accessed from either side. And the small zippered pocket at the top of the backside fits essentials like First Aid items (but nothing very big or bulky, like larger winter traction devices).

With a tester-approved, lightweight, simple corded system that secures the pack to the body, and a versatile in-between size, this is an overall comfortable hydration vest, ready for running adventures of any length.

Best Value Running Hydration Vest

Nathan Sports QuickStart 3.0 4-Liter Hydration Pack

Weight:12.4 oz with bladderSizing:One size fits mostHydration:Comes with 1.5 L bladderCapacity:4 L

Pros and Cons+ Push-pull valve on bladder keeps water from leaking+ Bladder is easy to fill– One size doesn’t fit all

It’s hard to find a good hydration vest that comes with a bladder for under a hundred bucks, but this one delivers quality at a bargain price. Testers appreciated the soft, breathable mesh that lies against the skin, and found the contoured back panel comfortable. “I like the way this pack rested against my body,” said one. However, with its one-size-fits-all sizing, smaller female testers found they couldn’t tighten the buckles enough for a secure fit.

We liked the simple pocketing—four drop-in pockets and a zippered pocket on the front, and a large back panel pocket (separate from the bladder sleeve) for added storage. The bladder that comes with this pack has a nifty on-off, push-pull valve system that works well to keep water from dripping. “The water flow was perfect and it’s easy to suck the water out,” said a tester.

Best Hydration Vest for Short Runs

Salomon S/Lab Pulsar 3

Weight:4.9 oz with flasksSizing:2XS-XL (unisex)Hydration:Comes with two 250 mL (8.5 oz) soft flasksCapacity:3 L

Pros and Cons+ Perfectly minimal+ Extremely lightweight– Small flask opening can be hard to fill

Sleek and minimal, this running vest can still comfortably carry 1000 milliliters of water: Two 250-milliliter flasks are included, and a 500 milliliter flask fits in the back lumbar pocket. The pack intentionally lacks backcountry features like a safety whistle or trekking-pole loops, and has room for just the essentials. It shines on shorter trail or road runs where you want to travel light and don’t need to carry much besides liquids (and maybe an extra layer).

The lumbar pocket is a convenient place to stash a shell if not being used for an additional bottle. A zippered front pocket and open-top back pocket provide easy, mid-run access to things like gloves or ajacket, and add functional storage while still allowing the pack to keep its streamlined fit.

Testers found the hydration pack rode remarkably comfortably. “The fit of this pack is amazing!” raved one. “It sits so close to the body and the adjustment cords are simple and minimal.”

Salomon Gravel Skin 2

Weight:5.9 oz with flasksSizing:XS-XL (unisex)Hydration:Comes with two 500 mL (17 oz) soft flasksCapacity:2 L

Pros and Cons+ Super lightweight and breathable+ Minimal bounce– Expensive

With a unique design—two mesh panels making “X” shape across the back—the Gravel Skin 2 running hydration vest feels minimal and stays in place while carrying two 500 milliliter soft flasks (included). A stretchy slide-through back panel at the bottom of the X makes shedding and storing a layer on the run easy without straining your shoulder or having to take off the pack. Open front pockets hold a phone or other small items you want to access, and a zippered front pocket secures a key.

The pack cinches across the chest via thin, adjustable bungee cords that are easy to release and attach. “I could hardly tell I was wearing this pack,” said a tester. “The front bungee cord closure—instead of a full zip with extra material—and absence of a full back panel, kept me from feeling sweaty.”

If you need more storage, we also like the larger capacityGravel Skin 4.

Best Hydration Vests For Medium-Long Runs

Salomon Active Skin 4

Weight:9 oz with flasksSizing:XS-XL (unisex)Hydration:Comes with two 500 mL (17 oz) soft flasksCapacity:4 L

Pros and Cons+ Two soft flasks at bargain price+ Versatile size– Material isn’t as sleek as higher-end Salomon packs

With four liters of storage and two 500 ml soft flasks, this hydration vest works as a short or long distance running partner at a steal of a price. The fit is comfortable and secure, even when fully loaded with a jacket and along-sleeve shirtin the main compartment. “This pack ends up feeling like an extension of yourrunning shirt,” said a tester.

The material is a tad heavier and noisier than what is used on the pricier Salomon packs, but, as one tester noted, “I don’t hear the fabric when I’m running, and I don’t feel it either.” Said another, “I can wear it on hot days with a tank top and not experience any rubbing or chafing.”

Best Hydration Vests for All-Day Epics

Nathan Sports Pinnacle Pro 6L

Weight:6.9 oz with flasksSizing:XXS-XLHydration:Comes with two 592 mL (20 oz) soft flasksCapacity:6 L

Pros and Cons+ Gender-specific fit+ Straws provide quick and convenient access to liquids– Straws annoyingly missed mouths of some testers

This running vest comes with two 592 ml (20 oz) straw-equipped soft flasks that allow easy hydration on the move; there’s no need to bend your neck down to reach a regular flask, or push one up towards your mouth. Six liters of storage space made this pack work for mountain adventures and long runs where layers and extra fuel and gear were necessary, and the soft, body-contouring material kept the fit stable and secure, even when fully loaded. Testers reported this pack to be “very breathable” and “super-comfortable”—especially the dialed-in, women’s-specific fit (don’t worry guys, it also comes in men’s.)

Salomon S/Lab Sense 6

Weight:4.9 oz. with flasksSizing:2XS-XL (unisex)Hydration:Comes with two 500 mL (17 oz) soft flasksCapacity:6 L

Pros and Cons+ Versatile capacity+ Good range of sizes– Hard to store phone with full flasks

Like all Salomon running hydration vests in this round-up, the fit and comfort of the Sense Pro 6 are fantastic. The soft and breathable mesh fabric allows a close-to-the-body fit and great breathability. “It contours to my body and has minimal bounce, even with full bottles, food, my phone, etc.” said a tester.

Pocketing is well thought-out: All testers especially loved having two zippered pockets on the frontside, although the space gets a bit squeezed when the flasks are full. One tester said she also appreciated the two small pockets on the shoulders for her inhaler and other medications, while another noted how the mouthpieces of the soft flasks angled conveniently towards her face. We loved this pack for short runs, and appreciated its ability to carry more gear when needed.

On Ultra Vest Pro

Weight:10.6 oz with flasksSizing:XS-XLHydration:Comes with two 500 mL (17 oz) soft flasksCapacity:10 L

Pros and Cons+ Mesh-lined back keeps air moving+ Removable 10L waterproof pouch boosts versatility– Pricey

The white version of the On Ultra Vest Pro just screams summer running, and we loved wearing it on scorching hot days. A stretchy, super-breathable mesh lines the entire backside, and soft mesh shoulder straps with a touch more structure make sure the running vest stays put. Multiple front-access pockets make organizing and accessing gear on the run easy, and the fit and security of this pack are fantastic. “The chest adjustments are easy to cinch tight for minimal bouncing or pack movement, and the fabric moves with your body and is very comfortable,” said a Boulder, Colorado-based tester who’s run dozens of 100-mile races.

What really sets this running hydration vest apart from the rest is a detachable, waterproof pouch on the backside, which enhances the pack’s versatility. We removed it for shorter runs when we only needed water, our phone, and lip balm, and used it when we needed to carry ajacketand extra food. The waterproofing gave us peace of mind, knowing that our layers would stay dry in a downpour.

Best Hydration Vests for Race Day

Osprey Dyna Pro 7 Run Hydration Vest

Weight:6 oz with flasksSizing:WS, WM, WL (Duro Pro 7 comes in MS, MM, ML)Hydration:Comes with two 500 mL (17 oz) soft flasksCapacity: 7 L

Pros and Cons+ Multiple, well-organized pockets+ Gender-specific fit– Expensive

Testers found the contoured yoke and harness on this running hydration vest (designed specifically for women) very comfortable, and loved the feel of the fabric, which one described as “super breathable and soft throughout.” They also praised the organization provided by the multiple pockets: four drop-in and one zippered pocket in front, a pass-through pocket on the lower back, and two pockets on the upper back. The large, zippered pocket on the upper back has a clever bungee securing system to keep big items from bouncing.

Race-ready features include a removable quiver sleeve that makes storing and accessing collapsible trekking poles quick and easy, a safety whistle, and a front harness for GPS trackers. Most unique: The two included 500-milliliter soft flasks come with plastic, wing-shaped stabilizers that made it extremely easy to return full flasks to their pockets. “This is a problem that I didn’t know I had,” said a tester, “but now I want all of my flasks to include these!”

Ultimate Direction Race Vest 6L

Weight:6.2 oz with flasksSizing:XS-XLHydration:Comes with two 500 mL (17 oz) soft flasksCapacity:6 L

Pros and Cons+  Super breathable+ Well-placed pocketing– Fabric doesn’t stretch much

Testers found this fully-featured running vest ideal for both race days and long adventures on the trail.  Gear storage is abundant, with two drop-in pockets and a zippered pocket in front and a pass-through and zippered pocket on the back. A large back panel can hold a hydration bladder and additional gear.

We appreciated how the two 500-milliliter soft flasks stayed secure thanks to a small bungee cord that loops around the cap. Larger bungee cords on the upper shoulders held collapsed trekking poles and other bulky items securely, and were easily removed when not needed.

The vest’s 100-percent recycled polyester mesh material that lies next to the skin is breathable and quick-drying, but not as soft or stretchy as some others we tested, which made the pack a bit harder to get on and off. Once on, however, the lack of stretch didn’t seem to affect fit and comfort. “This pack didn’t move at all,” said a tester. “I forgot it was on.” Bonus: The white color option we tested helped keep us cool on hot days by reflecting sunlight.

Salomon ADV Skin 12

Weight:11.3 oz with flasksSizing:XS-XLHydration:Comes with two 500 mL (17 oz) soft flasksCapacity:12 L

Pros and Cons+ Well-thought-out gear organizing pockets+ Customizable fit– Lacks a dedicated outlet for a hydration hose to thread smoothly to the front

This running hydration vest is a perennial favorite among our testers due to its adaptable fit, carrying capacity, organization, and comfort over the long run. This season, the Salomon ADV Skin 12 received some welcome updates that optimize fit and minimize bounce, including new shoulder straps and a new Y-shaped construction made with a mix of stretchy and supportive materials. Plus, it comes with new conical-shaped hydration flasks that slide easily in and out of the sleeves on the front shoulder straps.

One tester wore the ADV Skin 12 for 42 hours during a 100-mile race in the Swiss Alps on what she says was “very technical” terrain (we’re betting that’s an understatement), and reported that, “The pack held up fantastically.” She raved about the back storage that holds plenty of layers and how well the front pockets carry water bottle flasks. “This pack is so lightweight and doesn’t jostle at all,” she said.

The other front pockets are plentiful enough to keep a phone, food, and miscellaneous items separate and organized. Paired withSalomon’s Custom Quiver Pole Sleeve($30), which carries collapsible poles like Robin Hood’s arrows, this pack is ready for battle.

The ADV Skin 12 can fit everything you need for a triple-digit-distance run, yet one tester also noted that the vest “wasn’t cumbersome for a six-mile run where I wasn’t carrying much.”

Running Hydration Vest FAQs

How should a running vest fit?

Your hydration vest should be comfortable and fit your specific body. If you can shop in person, assess how the chest straps sit on your body, and if there are any points of irritation. See if you can adjust all the straps to get the pack nice and snug to your body, and jog around to make sure the pack doesn’t move too much. Hydration vests are often sold in men’s and women’s versions; women’s packs typically have more room around the bust, are narrower in the shoulders, and are shorter overall.

What size do I need for a running vest?

Since sizes vary between brands, start by checking the brand’s measurement guide on their website, and then measure yourself. The vest should feel snug, but not restrictive. If it’s hard to take a full breath without battling the straps, it’s too small. If there are gaps in the fabric around the shoulders and the pack moves too much on your back when you run, it’s likely too big. If you are maxing out the straps in either direction—cinched all the way in, or fully expanded—consider shifting sizes.

What features do I need in a running hydration vest?

Your preferred features come down to personal preferences and how you plan to use the vest. Some people, for example, demand a zippered front pocket, or pole storage, or large pockets capable of holding many easy-to-access snacks. Make sure the pack meets your specific needs: You’ll likely need a different pack for short runs around the neighborhood than for full-day (or multi-day) adventures.

How We Test Running Hydration Vests

• Number of testers:7 • Number of products tested:50+ • Gnarliest test conditions:A 100-mile ultramarathon through the Swiss Alps • Most common testing grounds:Trails along the Front Range of the Rocky Mountains

Most of our testing took place in Boulder, Colorado, and on trails deeper into the Rocky Mountains. Our hydration vest test team included seven women and one man who split up the testing by mostly comparing packs within one or two of the categories: small volume, medium volume, race packs, etc. One tester put every hydration pack through the paces.
