There’s been an explosion of running vests and hydration packs in the past few years. Not only does that mean there are more options, but they’re also more comfortable and functional than ever before. Improved designs have led to less bounce and chafing, and more comfort mile after mile.

Current authors Chris Carter and Matthew Medendorp are both religious trail and road runners, clocking endless miles each week in pursuit of PRs and podium finishes. They know the importance of proper hydration on long runs and settled for only the best in the creation of this guide.

From snow-packed trails in Eastern Sierra’s Mammoth Lakes to high-altitude training grounds in Northern Arizona, to the wilds of New Zealand, we’ve put a lot of miles on hydration vests. We tested for overall comfort, capacity, fit, and ease of use. And, while there isn’t a single hydration pack that will work for every person, we’ve included a variety of options to fit your style of running.

How We Tested Hydration Packs

Our Expert Testers

Chris Carter, one of the authors of this guide, is an avid ultra runner and is coming out of a season of constant competing in trail races along the East Coast. He can’t quite find the gumption to get into road running, but is a trail hog through and through.

Matthew Medendorp, another contributor, is a trail runner constantly looking for an excuse to venture off the tarmac. He cut his trail running teeth while living in Flagstaff, run-commuting and exploring the high alpine desert’s steep and dusty trails. These days you can find him in the Midwest, grinding out weekly miles over gravel and behind a running stroller (a Thule Urban Glide 2 Double, since this is GearJunkie) and diligently sneaking in pre-dawn trail miles.

Our Testing Process

We started by researching the best hydration packs and vests before picking 13 to test. We tested these vests and packs while running ~100+ miles throughout the San Juan Mountains in Colorado. Our testers have bushwhacked through Gambel oak, scrambled up peaks, and run smooth single track to test out the capabilities of these vests and packs.

We’ve tested every feature and put these packs and vests through their paces. The fabric has been stretched and stained, every pocket has been tried out, and the organizational systems explored. We’ve learned things about these packs and vests that the manufacturers don’t even advertise, and we’re doing our best to convey everything we’ve learned to you, whether this is your first running vest, or you’ve worn your last one to pieces.

Our Testing Grounds

For our 2024 update, we took our Buyer’s Guide finalists on two back-to-back trips in different environments. The first in the high desert and red rocks of Sedona, camping out at trailhead in an Outdoorsy rental for dawn patrol trail starts and convenient pack switches for our head-to-head testing. The second in a post-blizzard Mammoth Lakes, running the snowy trails and high altitude roads of the Eastern Sierra mountains where Olympians gather to test their lungs and Vo2 maxes against the thin air. 

We prioritized testing vests and packs in wide-ranging conditions: hot and dusty desert trails, cold and windy mountain passes, and humid rainy spring runs. We took meticulous notes across testing conditions and pack performance, settling on the results here.

Buyers Guide: How to Choose a Hydration Pack for Running

Running packs and vests come in all shapes and sizes. It’s important to consider what kinds of runs or adventures you plan to use your pack on when choosing the right one for you.

If you typically run a few miles a week, a recreational vest will be plenty. But if you have race ambitions, you may want to choose something more technical and geared toward performance. If you want to keep your gear closet slimmed down and like multipurpose gear, a hydration pack might be better for use while hiking, running, and even on overnight trips.

Read on to learn more about what to consider while choosing a running vest or pack.

Types of Running Vests

Recreational

Recreational running vests are more affordable than more technical options. That makes them a great first pick for someone who has never used a running vest before and wants to try one out.

Recreational running vests typically hold 1-2 L of water, enough for a 1-2 hour run or a race with lots of aid stations. They might have one main compartment and a few additional places to stash snacks, phones, and other necessities. But they’re not going to have all the bells and whistles of a more performance-oriented pack.

Performance

Performance running vests can look like a lot of different things. But they are generally oriented towards all-day runs, long trail races, ultra marathons, and technical trails.

Performance running vests typically use higher-quality materials which can make them more comfortable over longer periods of time. They also have many more features and ways to organize your gear, such as more pockets, pole and/or ice axe attachments, and unique ways to adjust the fit.

These vests can run a bit more on the expensive side, but are important elements of an ultramarathon kit, and are built to boost comfort and keep you hydrated in rough, remote environments. They are designed to reduce chafing over the long run, and be worn all day (and all night on occasion), without wearing the athlete down. The Salomon Sense Pro 10 and Camelbak Zephyr Pro are good examples of solid performance-oriented hydration vests.

Fastpacking

Fastpacking is distance trail running and backpacking at the same time. You’re running or hiking quickly, and while going light is a necessity, you still need enough gear to be safe and comfortable (enough).

For fastpacking, you need a pack that can move with you for long periods of time, but also carry enough gear for multiple days. That’s hard to come by, as many backpacks designed for day hiking are heavy and don’t have the features to carry the gear you need, but backpacking backpacks are far too bulky.

So fastpacking running vests and packs have emerged that walk the line between running vest and daypack. They have enough capacity to fit overnight gear but still fit close enough to the body that it’s not distracting while running.

Bottles vs. Reservoirs

Different types of hydration packs and running vests have different ways to carry water. The amount of water you want to carry will depend on how far you are going. For a 1-2 hour run, you will probably only need ~1 L of water. Whereas if you’re out all day, you might want up to 3-4 L of water throughout the day. Most running vests can hold up to 3 L of water — a 2 L reservoir and two 500 mL flasks.

Most running vests and hydration packs have space for a hydration reservoir in the back. This looks like a sleeve to slip a reservoir into. The best options have a way to hold up the reservoir so that while you’re drinking from it, it doesn’t slip down in the sleeve.

Some of the options on this list come with reservoirs, while others do not. That’s something to consider before purchasing. Also, consider the size of the reservoir. Most running vests and packs can fit a 1-2 L reservoir.

Some running vests also have pockets for flasks in the front. Many of them also come with flasks, which is something to consider when choosing a running vest. When flasks are positioned properly, you can drink while on the move, which is key for any sort of running hydration.

Flasks can also have a lighter weight than reservoirs. However, some tend to fall down or are hard to reach without a lot of work while on the move. Look for elastics to hold flasks in position even when they’re partially empty. Flasks also tend to be specific fits for each brand, so don’t plan on using a Balck Diamond flasks for an Arc’teryx vest, or vice versa.

Many runners prefer one hydration method or the other, while others use both. However you choose to hydrate, you just need to make sure to bring enough water for your run.

Capacity: Water & Gear

How much capacity you need will depend on what your runs typically look like. Someone whose average run is a 5-mile road run will have different needs than someone whose average run is a 20-mile mountain run.

Running vests and hydration packs come with anywhere between 2 L and 20 L of storage space. That typically describes the size of the main compartment, however many have lots of other pockets and features to stash gear. Think about what you might want to bring on most runs, and find a pack or vest that fits that amount of stuff.

For example, our tester knows that if she’s wearing a running vest, she’s probably going on a trail run. She likes to bring at least one layer, snacks, and up to 3 L of water on most trail runs. On mountain runs where the weather is variable, she may bring two layers, or other emergency gear. To fit all that, she needs at least a 5 L pack, and 10 L is very comfortable.

When thinking about how much water you need, consider if you will have any opportunities to refill. If you’re running a race, how many aid stations are there? How long is the furthest distance between them? It’s not worth bringing too much more water than you need, since that will just weigh you down. However, it’s a fine line to run since water is a necessity while on the move.

If you’re in the mountains, are there any opportunities to fill up water from natural sources? Just make sure to bring a water filter or some way to treat water if so.

Sizing

Getting the right fit is key for any piece of gear, but especially for a running vest. When possible, head to your local running store and ask for a fitting. For online shopping, take the time to measure yourself and refer to sizing charts.

Running vests should fit snuggly, without any bounce. You want it to feel more like a piece of clothing than a backpack. Ideally, you shouldn’t feel it move when you’re running. Some vests have elastic toggles to help customize the fit or accommodate layers, and others like the Arc’teryx Norvan have minimal adjustment points so honing in on the right fit is key for a good experience.

For women, you need to not only make sure the length and torso circumference is correct, but also be sure to take bust size into account. The women’s-specific VaporAiress offers two adjustment points for an easy fit, and our female testers were pleased with the overall fit.

Organizational Features

Extra features can make the difference between an OK vest and an awesome one. There are so many additional organizational features on different running vests. Here are a few we see a lot:

Trekking pole attachments: If you like running with poles, it’s great to have a way to stash them if you get tired of using them, or get to a section of trail you don’t need them.

Zippered pockets: Front zippered pockets are useful for phones so they don’t fall out of stretch pockets (it’s happened to one of our testers!).

Stretchy pockets: Stretch pockets of any size are great for not taking up space unless you need them to. Stretch pockets allow you to fit larger items than the space allows, and ensure that the item doesn’t fall out if there isn’t a closure. Some of our favorite running vests use stretchy material on the pockets and compartments.

Ice axe attachment: Some running vests and packs have ways to attach ice axes which can be useful if you like to go fast and light while mountaineering. Or if you like to run during seasons when there is still snow/ice in the mountains, lightweight ice axes can be good for safety (just know how to use them).

Compression straps: Compression straps can help you fit even more gear on your pack or vest. It’s an especially good way to carry extra layers that don’t fit in your pack or can be used to carry trekking poles if there isn’t another option. Compression straps are versatile and useful in a variety of ways while running.

Whatever pack you end up choosing, remember the goal is to get out and run. Use a vest to maximize comfort and hydration, and enjoy your time on the trail.

Breathability

When you’re out on runs it’s important to wear clothes and use gear that breathes well. Staying dry, or drying quickly, can be the difference between comfort and hyperthermia, especially in cold months or cold climates. And in the warm months, it can make the difference between a sluggish run and a feel-good run.

Many running vests are made out of material that allows them to wick sweat or dry quickly. Mesh materials can vent heat and keep you cooler. Or some vests and packs use ventilation to keep you cool while on the move.

It’s important to consider how well a running vest or pack breathes, especially if you know you sweat a lot.

Comfort

The ideal running vest is not distracting while on a run. If you’re trying on running vests, add some weight to them (water, layers, etc) and run or bounce up and down to mimic running. See if you notice the running vest. If you do, it will probably distract you, or even worse, chafe while on a long run.

Like all clothing and gear, the perfect running vest depends on your body shape, and your needs. There is no one “most comfortable” vest, since what fits our testers well might not fit your body as well. But look for something that fits tightly, with no bouncing or rubbing.

Try and go for softer materials, padding, and adjustability. These are all things that will help you be more comfortable, and thus run better, while out on the trail.

Visibility

It’s important to stand out when running on the trail or road — primarily in low-vis scenarios or after dark. During late-night dashes and early-morning jaunts along busy roads or mountain biking trails, lights and/or reflective strips are a must. If your routine frequently puts you in low-light situations, make sure you grab a running vest with ample visibility. While many vests on this list like the Norrøna senja 7 feature reflective logos/details, don’t rely on just those when running at night. Clip-on lights and light belts can help too.

Don’t want to worry about the hassle of dealing with dangling lights and extra accessories? Snag a vest like Nathan’s unique Laser Light Pack, which has a 6-lumen light strip that winds its way throughout the vest, affording on-demand visibility when the sun goes to bed.

Price & Value

Budget

Running hydration packs and vests can vary wildly in price. You can find them for anywhere from $50 to well over $200. Often, you’re trading thoughtful design and durability for low prices, but there are still some gems to be found in the sub-$100 range. Our best bargain option, the Nathan Quickstart 2.0 4L ($80), is a vest that offers 1.5 liters of water storage, enough room to store several layers when the weather gets warm, and a handy tube hook that keeps the hose from swinging around while you run.

Mid-Tier

Packs in the middle of the price range typically cost anywhere from $100 to $150. In this category, you’ll find more storage, durable materials, and a few more bells and whistles than you’ll find in bargain packs and vests. The Osprey Duro 1.5 Hydration Vest ($120) is a sleek pack that carries one liter of water, has a thoughtful array of easily-accessible pockets, and offers a no-bounce fit.

Premium

If you want a pack that’s loaded with features, be prepared to shell out $200 or more. Our top pick, the Norrøna senja econyl70 7L vest Hydration Vest ($229), is pricey, but it’s easy to see where every dollar went. It has features like hydration chest pockets, a hydration bladder sleeve, running pole attachments, and a whole lot more. Most importantly, there is almost zero bounce while running, thanks to the various adjustment points and suspension system.
