We've tested close to 30 unique running hydration packs in the past 7 years, with our top 14 in this review. We sought out vests that could carry the bare essentials comfortably, but in some cases, we chose to test packs that could carry much more. What differentiates a hydration pack for running from a typical backpack is the ability to access gear while on the move and a comfortable bounce-free ride. We tested new and veteran packs for this review, subjecting them to months of meticulous, head-to-head testing. Comfort, features, hydration systems, storage options, and each pack's volume to weight ratio are key elements of what we think makes the ultimate running companion. From hot weather jaunts to ultramarathon racing, we've compiled our data and experience to help you craft an informed choice.

Running doesn't require a ton of gear, but there are some key elements you can dial in to have a better experience. From running shorts to running shirts to trekking poles, we've got you covered. Our female runners have also extensively tested hydration packs in our women's specific review. Whether you're just getting started or are using a top-ranked GPS watch to train for an ultra, we're here to help you build out the perfect running gear kit.

Editor's Note: We updated this review on August 31, 2022, to add in updated products from Salomon, Ultimate Direction, and REI.

With the Ultimate Direction Ultra Vest 6.0, everything just clicked. It's more durable and rugged than the other top-performing vests, can still carry lots of gear, and is comfortable. A simple design with thoughtfully integrated features translates into a pack that is as intuitive as it is useful. Waterproof pockets and tough material choices will keep both gear and this vest running for many years to come. Soft trim along all edges and a fine micro mesh interior are comfortable against exposed skin. Add in a top-notch hydration system, and it's clear to see why we reached for the Ultra Vest 6.0 over and over again.

Dual fit systems provide enough adjustments to work for a wide variety of body types as well as varying assortments of gear and layers. We found the medium vest slightly larger than some other mediums, so if you are between sizes, we recommend trying on the vest if you have the opportunity. Compared to some of the other top-performing vests, the approachable price adds appeal for a wider audience. If you are a top mountain athlete competing in full-day events, this vest will perform. If you like getting out on hikes with your dog and need to carry extra supplies, this pack is easy to use and comfortable.

The REI Co-op Swiftland 5 redefines the standard of introductory running vests. At an affordable price, it's easy to use, highly adjustable, and capable of carrying a decent load. Our favorite thing about this vest is the intuitive design; at no point do you need to contort your body or undergo an unnatural movement to tighten or adjust a strap. We love that the amount of storage permits you to get out for full-day adventures with the necessary gear and some additional layers or medical supplies if need be. Compatibility with both a hydration bladder and soft flasks (not included) add to the versatility of this do-it-all vest.

For anyone considering trying out a hydration pack for running, but also considering using it for biking, hiking, rafting trips, or staying hydrated at festivals, look no further. With 5 liters of usable storage between the main blitz pocket, an external quick-stow pocket, and front chest pockets, you can bring almost anything you need with you with this model. Vests as feature-rich as this one normally don't have such accommodating fits, as they are designed for race-oriented ultrarunners. The Swiftland 5 is different — it has many high-end functional features for a fraction of the price.

The Nathan Pinnacle 12L is unmatched in the amount of accessible gear it can carry. The field of hydration packs for running is only getting stronger, and this pack still stood out amongst stiff competition. Twelve pockets and a hydration sleeve for a bladder provide extensive storage options for this vest, and the compatibility with soft flasks adds versatility for the user. The number of pockets is one thing, but the side-accessed kangaroo pockets are immense, and one of them is also accessible from the back of the pack for more rapid access at aid stations or when you're taking a break.

While this vest is pricy and made of lightweight, highly stretchable fabric, we still see value in a 12-liter vest that allows a runner to chug along without having to stop to access some of the main storage pockets across the back of the pack. At this point in time, no vest has a great trekking pole solution because poles are 15" long when collapsed, and most vests are barely this size. With all the movement of running, poles are bound to be a point of high friction if stored in any manner. If you store trekking poles in the vertical kangaroo pocket as intended, you can technically draw them from the pack while moving through the flank access to this pocket, but it's not a well-tuned system. We don't count it against any vest that you have to take it off to store the poles because the few vests with front storage options were also quite uncomfortable. We had very few slights to throw at the Pinnacle 12 — sure, it is heavier than some other vests, and the sternum straps are a bit stiffer, but we know this vest is reliable, and the user experience is refined to feel innate.

The Salomon ADV Skin 12 Set still stands among the best hydration vests we've ever tested. Not only does it perform excellently in all scenarios, but it can store a phenomenal amount of gear and strike a perfect balance so that every stride remains fluid. As you can imagine, comfort is of the utmost importance when running, and having a vest that can ride just as comfortably full as empty is a huge bonus. The innovative pocket design further seals the deal — we love the kangaroo pouches, a feature pioneered by this model and emulated by most of the other award-winning vests we tested. What's more, the mesh pockets are see-through enough to inform both the runner and crew what is in each area during races. Testers also thought the soft flask hydration system was the most versatile and comfortable system reviewed, and a heat protective sleeve (if you purchase a bladder separately) rounds out the feature set allowing you to add Salomon's proprietary 1.5-liter bladder. The pack can also house any hydration bladder if you remove the thermal sleeve.

Truthfully, our top three vests had us splitting hairs, trying to find the slight advantages of one over the other. You can't go wrong with any of them. If you prefer setting your fit preferences before a big outing and having fewer friction points during your run, we are certain you will like this vest most. If you like the ability to adjust your vest fit on the move as you burn through calories and drink down your water, then the Nathan Pinnacle will likely suit your preferences. Nonetheless, we always say comfort is king, and this vest scored as high as any other in the comfort category, so beginner or expert, we're confident you'll love this product.

The Salomon Sense Pro 5 continues the legacy of excellent lightweight trail running vests from Salomon. No other product lets people know you are a trail runner quite like this vest, as it means business and will be the sensible option for many runners looking to increase the distance of their outings. The included hydration soft flasks have a rigid bottom that is painful against the ribcage, and the mesh along the vest's collar is slightly rough against exposed skin. These are the two minor drawbacks that users make out to be more problematic than they are. You can trust us — if you are looking for a lightweight pack with perfect pockets that you can use for any distance, look no further. Read our full review to learn more about how we suggest addressing these drawbacks, as well as why we rave about this vest.

A stretch-conforming fit that is lightweight does have some tradeoffs. This vest doesn't have a waterproof pocket, and if you routinely overfill it, the material may stretch out in a way that negatively impacts the fit. But for runners looking to compete up to 100k or move swiftly through the woods on their own accord, this vest optimizes accessible gear storage and fit to match your highest performance.

Why You Should Trust Us


Our testing begins with identifying the best hydration packs available on the market for a wide range of running adventures. Over the last decade, we have tested countless vests, and each year as manufacturers update their offerings and new packs are introduced, we vet those options and update our review. We weigh all of the packs and then — you guessed it — spend a lot of time running with various gear setups to explore performance for a multitude of adventures. We want to know how these packs will perform for runners just starting to dabble with larger outings and for the top athletes competing in ultra-endurance races. In addition to our daily trail runs through the Elk Mountains, Sierra Nevada, or variable landscapes of Utah, we tested these vests in some ultras, including the Jemez Mountain 50 (NM), Western States 100 Miler (CA), and IMTUF 100 (ID) mile race. Bottom line, you couldn't find a better team to have put these hydration packs through the paces, pushing their limits so you can find the best match for your specific needs.

Our hydration pack for running testing is divided into five metrics:
  • Comfort (30% of overall score weighting)
  • Features (25% weighting)
  • Hydration System (15% weighting)
  • Volume to Weight Ratio (15% weighting)
  • Pockets (15% weighting)

In addition to these weighted metrics, we consider what type of runner each pack will perform best for, what type of running it is designed for, and how it stacks up on the trail. We consider testamonials in our selection process and test for any points of discomfort or shortcomings we read in customer feedback.

We have a bomber team of endurance athletes testing these packs. With bulging muscular calves and an affinity for getting lost, Jeff Colt, Andy Wellman, and Brian Martin make up our team of ultra-trail runners. They have all put in some serious time, chugging away on races ranging from 10 to 100 miles. Jeff competes internationally in trail races from 50k to 100 miles and trains locally in Colorado's Elk Mountains. Andy is a seasoned ultra-runner exploring the mountains of Colorado and coastal regions of Oregon by trail. And Brian is a Search and Rescue technician that enjoys spending long days on the trail all over the USA. They make a cohesive team that covers all the review bases.

Analysis and Test Results


We wanted to give each hydration pack for running a fair trial, so we spent months upon months doing a lot of running. We took these packs everywhere we went, from the high alpine to our local trails and then to the farmer's market. We wanted to know how their storage capabilities compared in terms of both size and design. In order to uncover the best packs, we paid attention to how user-friendly the hydration systems are, all the while comparing their overall comfort, fit, and weight. We have allotted a weighted ranking to each metric, but we urge you to review the scores and decide for yourself which categories are most important to you.


Value


The products in this review vary significantly in cost. We sought out a variety of packs that spread across the spectrum of affordability. We looked for those that were entry-level, minimalist, premium, designed for fastpacking, and some others to round out the field. We looked for a wide range of materials and designs and then chose the final contenders we wanted to take to the trails for testing. There are cost discrepancies, but we worked hard to identify competitive products that could break personal bests without busting the bank.

The more affordable vests generally have fewer bells and whistles: these are user-friendly, simple packs to help you drink water on the go. The more expensive packs have more specialized materials, more storage options, and designs that target running comfort and convenience. "Value," as far as we're concerned, is a function of price as it relates to performance. A pack may be cheap and crappy, or it may be a great deal that functions nearly as well as the most expensive pack. Similarly, an expensive pack does not necessarily indicate a great one. That said, we generally found that more expensive packs in this review do have more to offer and are constructed of higher-end materials that better suit and reflect the natural movements of running.

For example, the REI Swiftland 5 is a great value for the price, offering a snug, comfortable fit and ample storage for most outings in the mountains. You could certainly spend more money on a vest that performs at the same level without much benefit. The Salomon ADV Skin 12 Set is also a great value, with stellar comfort and the ability to seemingly never run out of storage space for food, equipment, or water. While the Swiftland isn't on the same level as the ADV Skin, they both represent great value for the right user. And, while the bottle carry isn't our favorite, the Raidlight Revolutiv 3L V2 is otherwise well-designed, absurdly light, and lands at a very reasonable middle-of-the-road price.

Comfort


Comfort is king. Learn it, love it, or lament out on the trails. The number-one most important metric to consider when picking a hydration pack for running is comfort. Thus, comfort is weighted more heavily than any other single attribute, and we think you'll understand why. Essentially, running is already uncomfortable, so why make it harder? If your pack is causing chafing, rubbing, or discomfort, you're less likely to use it and maybe even less likely to hit the trails for the long missions you've been scheming up. Thus, we put in the miles ahead of time: things that feel annoying at mile two can easily be a dealbreaker by mile twenty.


The most comfortable contenders are the ones that use an elastic and stretchy material to hug the body or use stretch in conjunction with static adjustable straps. Packs constructed of inflexible material that merely used static webbing for adjustments didn't perform as well. While straps, especially on the sides, allow for greater adjustability, they also rub and chafe more. Additionally, packs that include shoulder adjustment straps tend to be more comfortable than those without because of the fine-tuned fit. The most comfortable models we tested are the ADV Skin 12 Set and the Black Diamond Distance 15 — both are larger packs that really hone in on suspension and gear carrying ability.

The ADV Skin 12 exemplifies the necessary comfort level hydration packs for running should strive for. This vest feels as if it hugs the body so evenly that it's difficult to identify a place with more pressure or contact. However, it features numerous points of adjustability, matching premium comfort with fit. Other packs tend to place more pressure through the shoulders or have difficulty distributing weight with heavier loads like hydration bladders. Even when we purposefully loaded the ADV Skin unevenly, it still distributed the weight remarkably well. Additionally, the included hydration system, two 500mL soft flasks, conform to the body, adding balance and preventing unwarranted bounce.

Another primary factor in pack comfort is the materials used and the placement of those materials. The back material on the Ultimate Direction Ultra Vest 6.0 is a lightweight and ultra-breathable micro-mesh. While items that aren't in waterproof pockets might get wet with a light rain shower, the breathability far outweighs the slight downsides. This micro-mesh material does not stretch much, so UD used a four-way stretch, ripstop, nylon/elastane fabric in the pocket design to hold items snugly and prevent bouncing. The result of using well-thought-out integration of advanced fabrics is a design capable of taking you long distances in relative comfort. Time and time again, we reached for the Ultra Vest, not because it was among the lightest, but because it was among the most comfortable and easiest to use.

The Distance 15 from Black Diamond surprised us, as its main compartment has a conventional backpack shape, yet it was efficient at moving in the mountains and limited unwanted bounce. To balance the large rear blitz pocket, Black Diamond incorporated wider shoulder straps and adjustable ribcage bungees that cross three times to offer a secure fit across more surface area. In this instance, the combination of a static material with flexible straps still provides plenty of support and enhances the vest's comfort.

Both the Patagonia Slope Runner Endurance 3L and the Ultimate Direction Ultra Vest 6.0 combine static straps with elastic straps but with different design approaches. The Patagonia vest features two fixed P-cord chest straps and two elastic straps that run all the way across the back. They are integrated into the material, providing a cinch that supports plenty of weight and hugs the bag. The Ultra Vest features two static sternum straps with lateral stretch fabric. Both systems work seamlessly, showcasing the advantages of mixed adjustment straps.

Pocket location also contributes greatly to comfort. The UltrAspire Bryce has several different pockets on each wide broad shoulder strap, large compartment pockets on the back, and external storage. With so many pockets, the balance of the vest varies greatly depending on how it is packed. In contrast, the Raidlight Revolutiv 3L V2 has one large pocket on each very narrow shoulder strap and three small pockets situated in a wrap around the lower back. As the hydration flasks in the sleeves on the shoulder straps emptied, the pack still maintained remarkable balance, attributed to well-designed seams and pockets located closer to the center of gravity of the runner (less bounce).

Other packs tended to highlight one or two adjustment systems and put the others on the back burner. The North Face Flight Race Day 8L, for instance, paid no attention to the adjustment straps, which couldn't tighten adequately, limiting our ability to get a secure fit and causing the bottles to bounce excessively, even causing food to fall out of the pockets. This may not be a big deal for some runners, but when it comes to comfort, you shouldn't be willing to compromise — especially if you have some long, hard objectives on your list of goals. Our tester wears a medium in every model, but this medium was much too big with limited adjustability, causing chafing and an uncomfortable ride.

Nylon webbing is used on the chest straps in addition to elastic, but there are no other fit adjustments on the Flight Race Day. The nylon straps need to be longer to accommodate a greater range of fit. Without a good range of fit adjustments, the vest bounces an unusable amount.

Features


The most interesting part of testing hydration packs for running boils down to features and design. Whether you want to compare the minimalist race vests with the maximalist fastpacking vests, or the entry-level vests with those designed by professional ultra legends, it's fascinating to put these vests side by side and work backward through the thought processes that went into their creation. The UltrAspire Bryce XT comes to mind because loading this vest up took some time in the morning, and then we'd hit the trail and have no idea where anything was in the seemingly endless maze of pockets. But get this, there are only ten pockets, which goes to show how the real estate each pocket takes up and its accessibility play a role in ease of use.


It's critical that hydration packs find the balance between a rich feature set and the functionality of those features. Having all of the bells and whistles is only great if they are useful to have on a pack and don't detract from the fairly simple goal: effectively carrying food, water, and gear while running. The Patagonia Slope Runner achieved basic at its best, having a very simple and effective feature set. At first, we missed the zippered pockets on the shoulder straps we had grown accustomed to, but Patagonia intended to eliminate any excess features, and they achieved that in a beautiful basic vest. While the Salomon Sense Pro 5 is also minimalist, it packs a richer feature set that we love and offers more versatile storage solutions.

In addition to examining the features of each product, we took an in-depth look at how these features help or hinder the overall functionality of the pack. Taking the Bryce XT as an example, the features provided could be much more than necessary for some trail running applications. Some runners might wonder about the helmet carry system; what's that about? Who needs to haul an ice axe on a run? For a few runners, these features are what speaks to them. Maybe they are eyeing Longs Peak early season when the frozen morning snow allows for faster travel, the helmet will protect against rockfall, and the ice axe will come in handy on the afternoon glissade down the softening snowfields. We worked to review each subcategory or interest that our community of trail runners shares. We tested the Black Diamond Distance 15 to understand how another pack carries gear and water for an overnight outing and ridge-top scrambles.

Other subcategories we considered are simple entry-level vests that have straightforward functions, minimalist race vests that are still highly capable but have streamlined features, and vests more geared at longer races while offering more features and better comfort than their minimalist counterparts. Additionally, we discovered some vests had standout features that separated them from the rest of the field and worked to compare them in more depth.

Trekking poles have grown in popularity for ultra runners and casual runners on a mountain adventure. As the trekking poles serve more of a purpose on the ascent and are not used as much on the downhills, having the option to store the poles on the hydration pack can free up your hands for faster arm swings, balance, and accessing nutrition or hydration. Many of the vests we tested have the option to store trekking poles. Most commonly, the attachments are either along the bottom of the pack across the lower back, or on each side of the shoulder straps in front of the torso. Some packs fit the poles inside. We really appreciate how the ADV Skin 12 provides different storing options based on preference. Our preference is to have the poles stored along the shoulder straps as the vests that do this successfully without interfering with access to pockets or water keep a lot of the arm movement in front of the body, limiting contortions when you need to access the back of the pack. The Ultra Vest 6.0 also offers elastic straps that clove-hitch to different webbing tabs based on user preference. Some runs require frequent transitions between using and storage trekking poles, while on other runs, we might bring them along as a just-in-case.

For faster movement in mountainous terrain, the front clove-hitch attachments are best for pole storage if you need immediate access for the next climb.

Some vests incorporate features into the design of pockets, so there can be some cross-pollination between vests that have amazing pocket layouts and how they score for features. The Pinnacle 12 earned the highest score for features and for pockets, not a coincidence at all.

Hydration System


The thesis statement of our entire review, these packs have been designed to carry water and incorporate a system that goes beyond a regular backpack to address the bounce, jostle, and bound of a runner's stride. Most every vest we reviewed includes at least one of the preferred hydration systems: soft flasks, hydration bladder, or hard bottles. If a vest didn't include a hydration system, we made sure to call it out and took a single point off their score. We have lots of soft flasks at our disposal, but for a runner buying their first hydration vest, we think it is fair to ask that companies include some container or specify their reasoning for not doing so. Regardless, if you are buying your first vest and it comes with a bladder, also referred to as a reservoir, consider buying two soft flasks as well for extra water storage and to try out a different system for preference.


Most of these models are adaptable to use either chest-mounted bottles/flasks or a back-mounted bladder and hose setup. There are pros and cons to each, which is why we advise trying out both options. However, for this entire review, we describe and rank the effectiveness of only the hydration system included with the purchase of each vest, rather than every conceivable method of rigging the pack. If a system wasn't included with the pack, we went with what we thought worked best. Take into account the ability to expand your water carrying capacity before making your final decision. Another point is that your selection of hydration system will free up a respective pocket or pockets. For the CamelBak Ultra Pro, the pack comes equipped with hydration flasks, but we found they were positioned too low on the shoulder straps and preferred to use this pack with a bladder.

So much about the CamelBak Ultra Pro is great, but if the hydration system doesn't work, the vest won't be as useful. These hydration sleeves position the bottle too low, making drinking tricky, additionally, there are no bottle cinches keeping the bottles upright in the sleeves.

Bladder & Hose

The bladder and hose hydration system is one that we are all familiar with and is almost synonymous with the brand CamelBak. Other competitors make bladders now, and many use a slide-lock opening instead of the classic circular screw cap. Bladders, also referred to as reservoirs, typically hold between 1.5 and 2 liters of water and are secured in a sleeve pocket of the pack positioned against your back. Most packs now feature some way of keeping the bladder upright using a snap, velcro, or a tab, and unless that system is really frustrating, we notice little difference between competing designs. A hose stretches from the bottom of the bladder over your shoulder and has a nozzle on the end for you to drink from. The advantages of this system are the large carrying capacity and the ease of drinking from a bite valve that can be brought up to your mouth, keeping your focus on the trail ahead.

The disadvantages are that you can only have one liquid, and bladders usually don't work well with anything besides water as the hose is much harder to clean. Furthermore, they can be annoying and time-consuming to fill since they are on the inside of your backpack, and the tube, depending on how it mounts to your shoulder straps, can be annoying when it flaps around as you run. Some packs use a quick-release feature on the bladder so you don't have to worry about rerouting the tube when you go to fill up. Even with this, refilling bladders inevitably will slow you down in comparison to refilling soft flasks.

Some other nitpicking complaints we have about bladder systems are that the water in the hose is susceptible to heating up from the sun or freezing if it's frigid out. And, when you are carrying all of your water in one place, especially 2 liters, it sloshes around more fiercely. Despite the drawbacks, this is the most popular hydration system in a hydration pack for running.

The Nathan Pinnacle has one of our favorite hydration bladder systems, proving this setup is great when done right. It's lightweight, can be filled with one hand, and never leaked on us. The clever hourglass shape of the bladder worked well with the longer vest design and prevented most unwanted sloshing. Routing between fabric layers over the shoulder and under a loop provides comfortable hose management, and a magnetic clip keeps the hose stowed instead of flapping about. A small velcro tab at the top of the vest and the quick-release feature on the hose at the bottom of the bladder keep the bladder upright and easy to refill.

Most of the products we reviewed will accommodate a bladder, even if they don't come with one included (the one exception being the svelte Raidlight Revolutiv). If you're going to purchase a bladder separately, make sure that it is designed to be compatible with your pack.

Chest-Mounted Bottles

Mounting the hydration system on the chest is becoming increasingly common for running packs. Your liquids are stored in two bottles that are held by pockets, also referred to as hydration sleeves, on the chest attached to the shoulder straps. With two bottles, you can bring along water and an electrolyte mix, which can help you avoid bonking. With the bottles positioned on the chest, it is also easier to perceive how much fluid you have remaining. For racing, being able to quickly pop a bottle out of its sleeve and fill it up without taking the pack off is a significant advantage. Packs that incorporate front-mounted bottles into their design can strike a more balanced fit, as weight is more distributed across the runner's frame.

There are disadvantages to chest-mounted bottles. For one, now that sloshing water is front and center, and if the fit isn't right, it can be a lot more aggravating. Additionally, the hard plastic of bottles can irritate the ribcage over time. Hard bottles are still prone to sloshing but retain their shape, unlike chest-mounted soft flasks. The Ultimate Direction Marathon V2 High Beam features two small hard bottles.

Chest-Mounted Soft Flasks

The ADV Skin 12 Set uses chest-mounted soft flasks as its primary hydration system, and Salomon really nails it. Akin to the hydration bladder design, Salomon has elastic loops that keep the bottles upright and prevent them from moving around excessively. Other packs employ a similar design, like the Raidlight Revolutiv, but most of them don't function as well as the Salomon support loops. The Ultra Vest 6.0 is top dog here though, with its two 500mL flasks that fit into sleeves on the shoulders. An elastic strap also secures these in place, and this is the best execution of this design that we've seen thus far, though the positioning is slightly low for our preferences.

If you want to add a high-performing Salomon Speed Soft Flask to another pack, you can purchase it separately.

Another downside of utilizing soft flasks is the inevitable frustration of stuffing the bottles back into their pouches when full. We have yet to encounter a design where the bottles slip back in drama-free, but Salomon designs their soft flasks to be longer and thinner than most other brands, positioning them closer to the mouth and making them easier to get in and out of the hydration sleeve pockets. As mentioned above, another gripe with soft flasks is that you can spend time getting the fit of your vest just right, but as you drink your liquids, the soft flasks empty and contort, changing the fit of your vest and often causing small pain points.

Volume to Weight Ratio


We wanted to assess a variety of packs in this review, from minimalist race vests to larger fastpacking bags. In order to compare 1.5L vests side by side with 15L packs, we developed our volume-to-weight ratio criterion. The best packs have a higher value of over 1.0, while smaller and heavier packs will have a value below 1.0. The evolution of virtually all outdoor gear is to be lighter without sacrificing durability or functionality; weight is an important characteristic, which is why we believe that lighter is better, so long as the pack can still perform and carry the necessary equipment for the mission.


We weighed each model straight out of the box, with all the accessories and the hydration system that it came with, minus the water. We then took the measured weight and divided it by the volume of the vest's storage. Generally, the larger volume packs scored better (as having a larger denominator will greatly impact the score), and the packs made with high stretch materials often could carry more volume than advertised. As there isn't a great way for us to measure volume, we followed the measurements provided by each brand. In this right, the Volume to Weight ratio disfavored the Raidlight Revolutiv even though it is significantly lighter than every other pack and could seemingly fit just as much gear despite a listed volume of only 3 liters.

Regardless of this variable, many of these larger vests we tested are notably lightweight, while some of the smaller vests tested were included as price-point options and are built with heavier materials. It's worth noting that if a vest did not include a hydration system, we weighed it as is and automatically docked the score by one point.

Looking at the two factors in our volume-to-weight ratio, each offers valuable insight. While storage capacity should help you narrow down what you are looking for depending on your primary use, weight is a critical attribute to consider within each segment of volume. As this category assesses a range of pack sizes, this score reflects packs that are able to carry gear while remaining very light. Often you will be wearing your pack for hours on end in an environment where speed and efficiency are necessary. If we look at the heaviest and lightest packs in this review, it becomes apparent which packs are built with weight-conscious materials and which are generally bulky.

Beyond carrying water, hydration packs for running should carry the clothing, food, and equipment you need for a successful long run without disrupting your running stride. Adequate storage space is necessary to bring along what you need. This carrying capacity, paired with the weight of the vest, gives valuable insight into the quality of the construction, feel, and function of each pack. While this category still goes hand-in-hand with the one below, pockets, it allows for a more objective assessment of a pack's carrying capabilities given its size and weight, taking more of the pack's intended design into play, be it short race or long fastpack.


Minimalist race vests we tested performed really well in the volume-to-weight ratio, as they are designed to be lightweight and highly capable. We took it upon ourselves to weigh all of the vests, but determining usable volume is a bit trickier, so we opted to go with the purported numbers that each brand provided. The Salomon Sense Pro 5 is one product that gets slighted by this metric. While the 5L carrying capacity listed by Salomon is probably accurate for regular use and the long-term fit of the pack, we could fit just as much gear in this pack as others that advertise 10L of storage.

Our hope is that this criterion places vests that are designed to be smaller race-oriented packs on a level playing field with larger packs that are designed with more storage space. The Distance 15, for example, is a heavy-hitting, any condition, multi-day juggernaut and scores very high, despite having a point automatically docked for not having included soft flasks. When reading our reviews, it's important to keep in mind that a lower storage capacity doesn't make a pack worse. Consider what you need to bring with you on your runs and objectives before deciding bigger (or smaller) is better.

Pockets


Pockets as a category can be either straightforward, in the case of more traditional pack designs with isolated pockets, or more complex with modern vest designs that are a continuous landscape of pockets. For this reason, the pocket design on a pack is critical, as it impacts comfort, features, volume, and the hydration system options. We try to suss out the overall contributions of the pockets in the aforementioned sections, and in this category, we look at the number of pockets and the utility of each.


The liberal use of pockets may be the most notably different characteristic of a hydration pack for running as compared to a regular old hydration pack. Running vests are designed with many different pockets on the front of the pack, attached to the shoulder straps, and sitting on the chest or flanks, where they are within convenient reach of the runner at all times. The idea is that a runner should be able to grab whatever they need, whether it is water, food, cell phone, or salt tabs, while on the run and without needing to stop or remove the pack. Many packs now feature a kangaroo pocket, which has access points on either side of the pack and uses prime real estate across the lower back to store additional supplies such as a spare soft flask, or extra layer.

In our testing, the only pack that delivers accessibility to 100% of its pockets mid-stride is the Raidlight Revolutiv, which has all three zippered pockets in comfortable reach. The Revolutiv is quite small though, so the contenders with our favorite pocket configurations are the Pinnacle 12 and the Ultra Vest 6.0, which have tons of different options, all within reach and all made out of expandable fabrics to hold different-sized items.

It's also critical to know that the sheer number of pockets sewn onto each vest doesn't correlate to the score it received. While the contenders for our awards all had in the ballpark of 10 pockets, we rewarded the higher-scoring packs for their usefulness and design. To us, some essential features of a hydration vest are ample storage, at least one secure zippered pocket for small, easily lost items, and a design that places several pockets within reach while moving. The Pinnacle 12, Sense Pro 5, and ADV Skin 12 nailed all of these points excellently with a wide variety of pocket sizes, shapes, and volume, keeping everything within easy reach.

Another consideration with pocket design is the ability to carry a phone in an accessible area, so you can easily locate your position on a map or snap a quick photo. Some vests missed the mark on this, while others provided a couple of different pockets that could effectively securely store a phone and keep it readily accessible. The UD Ultra Vest has eight pockets and a rear bladder sleeve for plenty of storage and access while on the move.

Conclusion


Hydration packs for running are one of the more "niche" categories that we review here at GearLab. There are a whole host of great packs on the market if you're looking for something to accompany you on long hikes and bike rides. This category is aimed at runners, and each pack keeps the specific needs of runners in mind throughout its design. We accept that runners might also like biking, climbing, skiing, and hiking, but all of these vests are designed to remediate the expected bouncing of water and gear that is inevitable to our running strides. They fit tight to the body, have less storage than an average daypack, and are generally more expensive, featuring a bunch of details that non-runners may find obsolete. That said, if long-distance running is calling your name, you're in the right place, and we have the gear to get you where you want to go. Short of giving you our phone numbers, we're here to help, so narrow down what you are in the market for and read through those in-depth reviews. We are confident we have a good solution for you.
