The Nathan Pinnacle 12L is one of the most comfortable hydration packs available on the market today. Its abundant size options, contour-hugging female-specific fit, and ample storage capacity make it a top recommendation for runners of all kinds. This hydration pack has an impressive 15 pockets, making it an exceptional choice for your longest, neediest days in the backcountry. You'll definitely find yourself wanting to get out and run with the Pinnacle on your team.
The only real downside to the Pinnacle is the high price. Ultimately, the sheer number of features and comfortable assets makes it worth the investment, but we understand it's a lot of money to cough up. If a 12-liter capacity may be more than you need, there are smaller, more budget-friendly options available, like the 8-liter Salomon Active Skin 8. Still, if you are on the hunt for a long-lasting, high-capacity vest with a cozy profile, we think the Nathan Pinnacle is well worth the investment, especially for endurance runners.

Fewer adjustment options
The Salomon Active Skin 8 is a well-designed and comfortable vest at a great price. The durable ripstop body and soft bungee compression systems make for a hydration companion that will be with you through your trail race training days and beyond. The contoured fit and breathable pack panel are extremely comfortable and will suit a variety of body shapes and climates. Whether you want to run with a little bit of gear or up to 10 liters (we measured), this affordable pack comes with a strong endorsement from us.
The Active Skin 8 is available in four size options but lacks the variety of adjustment options other models offer. The sole adjustment point is via the front bungee, which limits the ability to change how the vest fits. Because the two ends of the bungee can be tightened independently, it is easy enough to cinch the body of the vest in a way that suits your body best. If you try the Active Skin 8 on and it fits, we are confident this vest will make an excellent addition to your running kit, no matter what kind of runner you are. Runners who want more adjustments for a customizable fit may prefer the 360-degree adjustment cords the Ultimate Direction Ultra Vesta 6.0 offers.
The shape of the soft flasks of the Active Skin make them much easier to replace on the go than many we have tested.

Might be more vest than some runners need
The Ultimate Direction Ultra Vesta 6.0 is a 7.8-ounce hydration pack that is ready to race. From its exceptional pocket placement to its external compression system, this is the vest we reach for when we know there won't be any time to fiddle with our gear. The Ultra Vesta offers 360-degree adjustment cords to ensure a bounce-free fit, while the soft flasks stay locked in so you can hydrate as you run. With safety features and thoughtful touches, such as specific waterproof pockets, this vest is a go-to winner for race-ready gear.
With a total storage capacity of 10.2 liters, the Ultra Vesta 6.0 may be more vest than many runners want or need. If you're looking for a more minimalistic style, plenty of hydration packs will suit your fancy, but the Ultra Vesta won't be one of them. The ripstop textile isn't as silky-soft as other running vests we tested, but this element doesn't detract from its overall comfort. If you are looking to invest in a piece of running gear that will suit your body shape and running needs, we have no hesitations about recommending the new-and-improved Ultra Vesta. If minimalism is more your speed, we recommend checking out the Naked HC.

Large storage capacity might be too much for some runners
Ultimate Direction released the Mountain Vesta 6.0 since our test cycle ended. This new hydration vest is wider in the back and wraps around the torso for a more secure fit. It also has updated mesh panels to help prevent chafing. We're linking to the Mountain Vesta 6.0 in our affiliate links, but our review is still for the 5.0 we tested.
The Ultimate Direction Mountain Vesta 5.0 is another favorite of our testing team for grueling alpine jaunts. This vest truly fits like a vest instead of a miniature backpack, allowing the external compression system to keep up to 12.7 liters of gear secure as you tackle the trails. We also love how many zippered pockets and self-locking bungees there are on the vest. This adds a great sense of security so you can focus on the technical underfoot terrain, not the safety of your gear.
The external compression bungee of the Mountain Vesta 5.0 is super long, which is great if you max out the storage capacity. However, if you prefer to carry less gear, this can be somewhat annoying. The sheer capacity of this vest makes it a less desirable choice for runners who don't want to tote excessive amounts of gear. There are plenty of hydration vest options with a smaller carrying capacity, so if over 12 liters seems too much, we recommend an option with a more modest storage volume. While on the pricier side, if the Mountain Vesta checks all of your boxes, it is a worthwhile investment. Still, those who only need to carry a few things may fare better with the 3-liter Naked HC or 6-liter Osprey Dyna 6.

Poor volume-to-weight ratio
The Naked HC is a minimalistic vest unlike any others we have seen. With a total weight of just over 5 ounces, this compressive vest fits more like a sports bra than a standard hydration pack, and the carrying capacity depends on the size you purchase. This is one of our favorites for light days. If you are a minimalistic-style runner who only wants to carry the basics, this zippered-front vest will be a great match for you.
With the Naked HC, the compression of your gear is based on how secure the zippered closure is, so it is important to purchase the correct size. Unfortunately, this can be a little tricky because this vest lacks bungees and straps for customizing the fit. If you only want to purchase one hydration vest, the small gear volume this model offers may not be enough to accommodate a variety of run lengths. The modest capacity and bra-like fit make the Naked High Capacity our true favorite for lighter days when we only want to stash the basics. But for longer runs, the Nathan Pinnacle 12L offers ample storage and a comfortable contour-hugging fit.

Heavier because of internal frame
If you want an adventure-ready hydration pack with a moderate storage capacity, look no further than the Osprey Dyna 6. This hydration pack has an internal frame with a strong compression system, which really makes the backpack-like fit work. The textiles that make up this pack are far more rugged feeling than the bodies of many of the packs we have tested, and we love it. We never felt uncomfortable running in this pack, even when we maxed out its 6-liter capacity. The hydration bladder includes well-engineered elements to ensure a slosh-free run, making this bladder one that we want to use in every single one of our packs.
The Dyna 6 is a little heavier than some, which adds to its overall lower ranking in the volume-to-weight ratio metric. The internal frame contributes to its weight, but this element also helps keep your gear snug against your body during runs. The front closures are a little tricky to use at first, but once you get the hang of them, they are just as simple, if not more functional, than many other closure systems we've tested. If you're shopping for a mid-range capacity vest with features truly built for gritty adventures, this is most likely the perfect option for you. But if you want the best volume-to-weight ratio, the Nathan Pinnacle 12L will save you a few ounces.

Why You Should Trust Us
We couldn't wait to get running immediately upon receiving a box full of hydration vests designed specifically for women. In addition to rotating through the vests to ensure equal in-depth testing time on the trails, we wore them around our homes and parks to get to know them better. We specifically loaded each pack up with the same amount of gear and voice-dictated notes into our smartphones while we ran, hiked, and even post-holed through the snow. A few of the hydration packs in our roundup were uncomfortable immediately. Still, we toughed it out and allowed our skin to chafe so that you can be certain that you're receiving unbiased, authentic, and exhaustive evaluations.
Our testing of hydration vests for running is divided across five rating metrics:
Comfort (30% of overall score weighting)
Features (25% weighting)
Hydration System (15% weighting)
Volume to Weight Ratio (15% weighting)
Pockets (15% weighting)

Our women's running hydration pack review is led by Ally Arcuri, an exercise specialist and experienced ultramarathoner. Ally remembers buying a CamelBak made for children back in the mid-2000s to satisfy her trail running needs in Lake Tahoe, CA. Since then, she has run her way across the beaches of Southern California and Mexico, the Rockies in Colorado and Wyoming, the deserts of Utah, the streets of Chicago and New York City, and most recently, the forests of the Pacific Northwest. According to her loved ones, Ally drinks more water than humanly possible, so, of course, she is an authority on testing hydration packs. Ally earned her Bachelor's degree in Kinesiology and has her 200-hour Yoga Teaching Certificate, so she has a keen eye for proper posture and biomechanics. When she isn't traveling and searching for places to run, you can find her teaching yoga or learning how to AquaSkip in San Luis Obispo, CA.

Analysis and Test Results
To ensure a fair trial for each hydration pack we chose to test, we ran a ton. We usually run a lot, but with these packs on our backs, we ran even more. We spent months testing, retesting, and evaluating each one. We bagged peaks, ran through dense forests, and surveyed each vest individually before bringing them together in a head-to-head competition. After we exhaustively tested each pack, we compared them to each other over a variety of metrics. We analyzed the comfort and fit, the intelligence and functionality of the hydration system, available features, and ease of use. We weighed each vest and assessed their maximum storage capacities, and you know we explored the depths of each pocket. We awarded each contender a specific numerical score in each metric. We encourage you to read on to determine which female-specific hydration pack for running has the potential to be your everyday sidekick.
Value
It's no secret that hydration vests can often cost a pretty penny and then some. While many of the pricier vests offer a more comfortable fit, more features, and more moisture-wicking material, we did not find this true across the board. There are rugged and durable options in the lower price ranges that truly impressed us. We were pleased to find that the divergent prices don't necessarily mean you're getting a lower quality or lower-performing hydration pack just because you spend less.
The vest that provides the most on a budget is the Salomon Active Skin 8. This comfortable, breathable, and well-featured pack is well-priced and comes with our highest accolades. The Nathan Trailmix 7 is another well-engineered, comfortable running pack with smart pockets and a thoughtful hydration system. Though simply designed, its features and price tag make it a worthy budget buy. Finally, the REI Co-op Swiftland 5 is another pack offering function and affordability.
The flasks of the Ultraspire Momentum 2.0 ride a bit lower than we like, but the upper bungees help to create a reliable hydration system.

If you don't mind spending some shillings for an even more comfortable ride, it's worth it to invest in the Nathan Pinnacle 12L. The Pinnacle is supple and breathable with anti-chafe technology and a whole lot of storage space. If you want an ultra-soft vest, check out the silky Salomon ADV Skin 5 Set The ADV Skin fits in a fashion similar to the Pinnacle but offers soft flasks and a smaller storage capacity, two elements you may prefer. Either pack will serve you well over the long haul, which is also a solid way to approach value.

Comfort
Comfort is one of the most valuable components for assessing running gear that is intended to be worn for long periods of time. We measured comfort by running in all of the hydration packs for many miles.
Even for those of us who love to run, running is hard. We wanted to evaluate each vest's ability to remain comfortable when the terrain and mileage are grueling. We spent months testing through myriad weather patterns to ensure each hydration pack got a fair trial on the trails. We assessed each pack's comfort on cold days with long-sleeved layers, on rainy days atop our favorite running jackets, and on hot days in tank tops with the packs directly against our skin.
We made sure to test each hydration vest in a variety of climates to ensure that the information we provide you is the best and most relatable.

Even the more rigid and toughly constructed packs were generally quite comfortable, which is a huge win for female-specific running vests as a whole. We tried each pack on with different hairstyles to see if any vest pieces had an appetite for human hair (unsurprisingly, Velcro LOVES to get all wrapped up with long hair). We even made sure to test each vest with a small necklace on to see if that interfered with its comfort at all.
We love so many things about the Nathan Pinnacle 12. But we despise how this triple layer of Velcro was constantly snagging our hair.

We noticed a trend amongst the hydration packs that scored well in this heavily weighted metric. Three of our top contenders are made of supple and forgiving yet contour-hugging textiles that wick away moisture and stay in place. Even though most hydration packs for running are frameless, some offer more boning and ribbing than others. Across the board, the more comfortable the vest, the less structure it has. Some vests, like the Salomon Active Skin 8, have exceptional breathability, which also adds to well-rounded comfort.
The frame and stiff structure of the Osprey make it less soft and supple when compared to other vests. Because of how well this vest's body is engineered, we found the frame and boning to be super comfortable on our longest runs.

We enjoyed the understated comfort of both the Ultimate Direction Ultra Vesta 6.0 and the Ultimate Direction Mountain Vesta 5.0. Both are constructed of highly breathable nylon mesh and offer plenty of cords and bungees to adjust the pack to fit the specific shape of your body. Both Ultimate Direction packs are easy enough to adjust that you can find a snug fit whether you are running in one thin shirt or multiple layers of technical gear.

The Naked High Capacity is unlike any other hydration pack for running we tested. It offers great comfort with a more streamlined and tight fit. Instead of wearing your hydration vest over your clothes, the Naked vest is essentially worn as an additional garment, hence the name. Choose your size wisely if you opt for this svelte running vest. You'll love its softness and the way it offers extra breast support when it is zipped up.
The Naked HC fits more like a garment than a piece of a gear, making it a vest that we loved to wear on especially warm days.

The Salomon Active Skin 8 is made of a lightweight ripstop material and provides stretch and comfort in all of the right places. The bungee and hook closure system on the front is comfortably unintrusive and flexible. This system allows you to tighten the pack to ensure the least amount of bounce possible, but the thin cord bungees mean you can still breathe easily without noticing any restrictions.

Features
Features is a catch-all type metric that we use to define all of the bells and whistles included with a particular hydration pack for running. We tested this initially by exploring what each vest offers in specific storage accessories and safety features. We took each vest and its features out into the field and engaged them in a side-by-side comparison. We evaluated the features promoted by each pack's manufacturer and tried them out in various ways.
We love that most of the vests have added safety features. In particular, our favorite component is the safety whistle. We tend to pack a lot of safety gear when we trek into the mountains, so it is a real treat to have a whistle included. We blew each whistle with all our might and found the one included on the Osprey Dyna 6 to be the loudest and most reliable. Furthermore, the Nathan Pinnacle includes a covertly stashed, loud whistle that could attract attention deep in the trails if you find yourself in a pinch.
Both Ultimate Direction packs that we tested have a pass-through pocket and a small loop to secure the whistle. This prevents it from bouncing while you run, a thoughtful feature that we think deserves praise.

We evaluated each hydration pack's trekking pole holding system. The more secure the holders, the better we felt running with our poles — no big surprise there. Both the Osprey Dyna 6 and the Nathan Pinnacle offer secure and designated spaces for this, making them two of the most comfortable packs to use with your favorite trekking poles. The Black Diamond Distance 4 features a unique Z-storage solution for trekking pole storage. This pack utilizes a loop and bungee system that can be stashed into specified pockets when not in use. Being able to attach large poles diagonally across the back of the pack is a comfortable way to go. We tested with a particularly large and clunky pair of poles but ultimately found this to be an attribute. We strung our poles up in different ways to find the most comfortable way to haul them.

We observed that many of the packs have reflective elements to ensure visibility while running in dark or hazy conditions. The rise of adventure races and overnight ultras makes small details like this vital to staying safe in the backcountry. Reflective details are also paramount for runners who like to be out at dusk or dawn. If you tend to run in low light conditions, ensure that you opt for a pack that has all of the features you need and also includes reflectivity for safety.
The reflectivity of the Pinnacle 12 adds an additional safety feature that we love.

Hydration System
Some runners love soft flasks while running; other runners prefer a hydration bladder. No matter your preference, we can all agree on one thing-- hydration matters! Some hydration packs for running come with soft bottles, and others come with bladders. Most notably, each and every hydration pack for running offers the option to run with bottles, a bladder, or both. We love to see most hydration bladders being made with a fold-over closure system. This style of closure is better at preventing leaks. The slide-across clips all have holes to secure Velcro loops through to maintain the thinnest fit possible against your back.
While assessing hydration systems, we were ruthless in our observations. We are serious runners, and a leaky bottle could truly lead to our unraveling while deep in desolation; running out of water is a run ruiner. To allow each hydration system a fair shake, we ran with each pack as intended to begin. After each maiden voyage, we ran with our hydration bladders half full without extra gear to assess the sloshing of each system. We never encountered any sloshing with the soft flasks, though they are definitely not created equal. Soft flasks that utilize more severe shapes tend to be the easiest to get in and out of the pockets at an aid station or at your own kitchen sink.
Though not all flasks are the same, if you want a slosh-free ride, flasks are superior over bouncy hydration bladders.

Nathan employed an hourglass-shaped, insulated bladder in the Pinnacle 12L. This bladder style is comfortable and awesome when gear is stowed in the back of the pack, but without gear, this shape still sloshes like the less contoured ones. Some hydration packs for running thoughtfully include a magnet system. There will be a small magnetic clip on the hose and a corresponding one on the chest strap or ribbing. This addition helps place your hose, whether you want it looped up towards your mouth or hanging down across your chest. Options with this magnet included earned higher marks due to their sheer convenience.
Some hydration hoses are longer than others. Ultimately, it is up to you to determine what kind of hydration system best suits your needs.
Credit: Ally Arcuri
Our biggest observation about soft bottles is that they have to be placed just so to be functional while running. Unlike a hose, which can be grabbed and placed in your mouth without even looking down, the bottles require more attention. We found that some bottles didn't seal well and leaked and that others had to be fully removed to drink from them. The Salomon ADV Skin 5 Set came equipped with an insulated sleeve, which really upped the ante on its hydration system. The Salomon Active 8 utilizes bendable straws to split the difference between low-riding flasks and the convenience of a hose. Ultimately, this design proved to be our favorite and you can also carry a bladder if desired.

Because of the tight-fitting vest, the soft flasks of the Naked HC have minimal opportunities for bouncing. Since this pack rides higher than average, the mouthpieces are also always just within reach. We found the same technology in play with the Ultimate Direction Ultra Vesta and Mountain Vesta.

Volume to Weight Ratio
We used a volume-to-weight ratio to fairly measure each hydration pack's storage capacity relative to its weight. Since hydration vests tend to be made of different textiles and components, we use this equation to assess each gear-hauling capacity accurately. We divide the carrying capacity (liters) by the weight (ounces) to calculate this ratio. The bigger the number, the higher the score, but if you know that you want a vest to carry only what you need, it is worth considering some of the lower scorers in this metric.
The Pinnacle has a ratio that is bigger than most. However, it weighs in a bit higher than average. Still, its volume-to-weight ratio is the best in our roundup because of how much gear it can haul. The Mountain Vesta scored lower based on numbers alone, but if you want a super-hauler pack, it's worth looking into, as is the Ultra Vesta. It may sound like we are splitting hairs, and in truth, we are — all in an attempt to separate the good from the great.
The Mountain Vesta has a huge capacity but weighs in higher than average, which ultimately lowered its volume to weight ratio score.

Another element we noted while assessing this ratio is the weight distribution of each pack. Some hydration packs for running fit like mini backpacks with pockets on the front straps. Others fit more snugly, like a vest. Overall, we found that the apparel-like, vest-structured options had better weight distribution for running. To measure this, we stuffed each vest full of more gear than we could need for a day on the trails. As we ran, we noted any bouncing, joint aches, or changes in gait patterns caused by wonky weight dispensation. Even with their exceptional carrying capacities, the Nathan Pinnacle, Ultra Vesta, and Mountain Vesta were the clear winners. These vests seamlessly distributed their 10-12+ liters of gear so that we never felt weighed down or off-balance. The weight distribution of the Naked HC, Salomon Active Skin 8, and Osprey Dyna 6 are incredibly well-designed as well, allowing you to comfortably carry everything you need.
We love the snug fit and intelligent weight distribution of the Osprey Dyna 6.

The REI Swiftland 5 surprised us by being super comfortable and freeing, despite its poor ratio. It is a mini backpack-style vest, but with strong straps and a haul-bag-like main compartment, it stays snug and even during grueling trail days. The Amphipod PureRun Minimalist 24 is another vest that has a poor volume-to-weight ratio, but it is worth considering if you want a truly minimalistic vest. The Amphipod weighs less than many of the larger vests at just 7.4 ounces and can hold up to 1.6-liters of essential gear.
The REI Swiftland is a budget buy that will keep you relatively happy on the trails.
The Amphipod is a low-riding, minimalistic vest that can hold only what you need.
Pockets
Pockets are important, and we love evaluating them. We went far beyond simply counting the pockets of each hydration pack for running, though we did that too. We utilized each pocket for different items as we ran, making sure to switch up our systems every so often. We analyzed how accessible each pocket is on the move, which are safe for stashing your valuables, and which are best for providing easy access to outer layers when the weather turns.
Our most pocket-full vest is the Nathan Pinnacle 12L, which boasts an impressive 15 total pockets. As is the case with the Pinnacle, we discovered that vests with well-dispersed pockets generally offer better weight distribution throughout the vest, ultimately leading to better comfort. The number of pockets on the Pinnacle is awesome for keeping belongings organized. Having a pocket dedicated to gels, one for electrolyte tablets, one for our handkerchief, and one for our phone up front makes grabbing and going easy.

Both the Ultra Vesta 6.0 and the Mountain Vesta 5.0 scored well in this metric. Not only does each vest offer ample storage in secure pockets, but the pockets are precisely placed. The Mountain Vesta features a large clamshell pocket as its main compartment on the back, similar to that of the Ultra Vesta. Even the textiles under the arms of both vests are laden with functional pockets. We emphasize the word "functional" because we often find that shallow pockets are not the most useful. When it comes to hydration vests made by Ultimate Direction, though, the pockets have fantastic closures and placement that encourage freedom of movement. Both the Mountain Vesta and the Ultra Vesta feel like they were designed for runners, by runners.
This stealthy back pocket is accessible without removing the pack. While you cannot reasonably dig into the main compartment without taking the Ultra Vesta off, the majority of the pockets can be accessed with the pack securely attached to your body.
Credit: Ally Arcuri
Even though the Ultraspire Momentum wasn't the highest scorer overall, the pocket structure of this pack is worth swooning over. They are uniquely placed with creative closure options. Since this vest provides flask holders in the lower portion of the back panel, the front straps are fair game regarding gear storage. The front pockets do make great flask holders, so it is up to you how you want to configure your gear. The front pockets feature shock cord closures, which allow for comfortable and safe storage. The pocket placement of this unisex vest does a fantastic job of allowing full range of motion movement as you run — even when the pockets are fully loaded with snacks.
