We’ve all experienced the inconvenience of fumbling with a sweaty water bottle during a long run or wish we could have hands-free hydration during a difficult hike. A hydration pack, which stores your water or hydration solution away for easy access, is a great option for endurance athletes and hiking enthusiasts. Some of these hydration packs include a bite valve and built-in straw for hands-free hydration; others can double as a hiking backpack with multiple convenient storage pockets for packable flasks. If you need a hydration pack that can also store your hiking shoes, hiking poles or other gear, we’ve got you covered. Whichever style you prefer, there is bound to be a hydration pack option that suits your needs and makes your outdoor exercise more enjoyable.

In this article, we’ll share eight best of the best hydration packs out there, sorted by activity. We’ve included all the information you need to pick the best one for you based on your budget, body type and exercise needs.

Best Hydration Pack for Hiking: Nathan QuickStart 2.0 4L

Key Features:

• Price: $80
• Weight: N/A
• Gear Capacity: Four liters
• Hydration Capacity: 1.5 liters
• Number of Pockets: Four

Hikers must be able to tolerate a vigorous endurance workout while trekking through the natural elements. Whether it’s sunny and warm, windy or raining, maintaining adequate hydration is essential for staying safe while hiking. And because hiking may involve bouldering, climbing or the use of hiking poles, all of which require the free use of one’s hands, carrying a water flask by hand on a hike is out of the question.

The answer to the dilemma of hydration while hiking is the Nathan QuickStart 2.0. This slim backpack can store up to four liters of gear as well as one and a half liters of hydration. It is made with four convenient pockets for storage of small items or electronic devices. We love the reflective details for safety in low light and the wide variety of color options. This backpack includes a Nathan-brand hydration bladder with a straw and bite valve. The back panel is made with a breathable mesh material to keep you cool, and one of the pockets is made to store an extra water bottle for additional hydration. The bag’s fabric is safe to hand-wash in case it gets soiled with sweat or mud on a day hike.

Though this is an excellent hydration pack for hiking, there are a few potential drawbacks. For one thing, this pack is only available in one size. The chest strap is adjustable for a customized fit, but hikers with larger bodies may struggle to fit in this hydration pack. If that’s the case, we recommend you check out another one of the hydration packs on our list, as most of them are available in multiple sizes. Some people also report issues with the hydration bladder being difficult to drink out of, but Nathan is generally able to fix this issue by sending a replacement. In general, its durability, washability and impressive hydration capacity make this a reliable source of hydration while hiking.

What we like:

• Tons of color options
• Reasonably priced
• Extra bottle pocket

What we don't like:

• Doesn’t fit well on larger bodies
• Water bladder can be difficult to use

Best Hydration Pack for Mountain Biking: Osprey Raptor 14

Key Features:

• Price: $90.50
• Weight: 1.75 pounds
• Gear Capacity: 14 liters
• Hydration Capacity: 2.5 liters
• Number of Pockets: Five

Compared to activities done on foot, mountain biking comes with a different set of hydration needs. You may need to carry a larger volume of gear, or more water as you travel over great distances. That’s where the Osprey Raptor 14 hydration pack comes in. This pack is large and sturdy enough to meet your hydration needs for mountain biking. It has a gear capacity of 14 liters, which is far more than the other hydration packs we feature on this list. It also has a hydration capacity of two and a half liters, allowing for plenty of water during long, arduous rides. There are five pockets for storing gear, fuel and electronics. This pack also features both a sternum strap and a hip belt for maximum security.

The Osprey Raptor 14 comes in three colors and one size. The sternum strap and shoulder straps are adjustable for the best possible fit. Some taller people say the hose included with the pack is too short to work well with their stature, so if you’re much taller than average, check out one of the packs with multiple size options. There’s also the weight of this pack to consider. A side effect of its size and storage capacity, the Osprey Raptor 14 weighs in at 1.75 pounds—by far the heaviest pack on our list.

If you’re looking for a dual-use hydration pack that you can also use while hiking or running, you may want to check out one of the lighter weight options. For mountain biking, though, the extra storage space and durability of this pack make it well worth the extra ounces. It may also be handy as a work backpack for any cyclist commuting via bike, thanks to its large storage capacity and extra support straps.

What we like:

• Large 2.5-liter water reservoir
• Plenty of room for other gear in pack
• Hip belt for maximum security while riding

What we don't like:

• Hose may be too short for taller people
• Flimsy mouthpiece

Best Hydration Pack for Men: Osprey Skarab 18

Key Features:

• Price: $59.50
• Weight: 1.10 pounds
• Gear Capacity: 18 liters
• Hydration Capacity: 2.5 liters
• Number of Pockets: Three

You may have noticed that a few of the hydration packs we’ve shared so far have size limitations that make finding the perfect fit a challenge for some folks. It’s understandable, given the wide range in body types among athletes and their different physical needs and preferences. But when we set out to search for the best hydration pack for men, we knew we needed to choose a hydration system that offered a comfortable fit for male bodies. That’s why we chose the Osprey Skarab 18 hydration pack. This large pack has enough room for 18 liters of gear as well as a whopping two and a half liters of hydration. We love that it has capacity for enough water to last through a long day of hiking, cycling or trail running. Its bucket-top style makes accessing your gear or refilling your hydration bladder simple. Though this backpack is only available in one size, its weight and dimensions work well for men, and the adjustable straps near the sternum, shoulder and hips allow you to customize the fit. You can choose from three cool, modern colors for this pack, and the reasonable price allows you to devote your extra resources to other gear, shoes or clothing.

The Skarab 18 includes a hydration pack made by respected brand Hydrapak, and users report that the water reservoir holds up well with use. Some folks report having trouble with the magnet that attaches the water hose to the reservoir. Osprey’s generous return policy should cover you in the event you have problems here, and these complaints are rare. This pack model also includes just a few internal and external pockets. This makes it perhaps better suited for hiking or cycling, when it isn’t inconvenient to have your valuables packed away in the depths of your day pack. But if you don’t mind the open storage style, you’ll find that the Osprey Skarab 18 is an excellent hydration pack for men.

What we like:

• Reasonably priced
• Good water capacity
• Adjustable straps

What we don't like:

• Only a few pockets
• Water hose magnet needs work

Best Hydration Pack for Women: Salomon Sense Pro 10

Key Features:

• Price: $135
• Weight: Nine ounces
• Gear Capacity: 10 liters
• Hydration Capacity: One liter
• Number of Pockets: Seven

Female athletes often struggle to find good-fitting gear, since so many types of athletic gear presume male athletes will be the primary users by default. But when it comes to hydration packs, there’s no reason to settle for an ill-fitting unisex option! Instead, we recommend the Salomon Sense Pro 10 hydration pack, which is made for women’s bodies. The Sense Pro 10 is meant to fit closely against the chest to prevent the hydration packs from moving around while running or doing other vigorous activity. Because it is designed to have a tailored fit, this hydration pack comes in five distinct sizes, each of which is also adjustable using a set of front-closure bungees. Two small hydration flasks with bite valves are stored on the left and right for hands-free hydration. There are seven pockets around the pack, including a large one in the back panel for gear storage.

This hydration pack is an incredibly lightweight piece of gear, weighing in at just nine ounces. For this reason, it’s an excellent choice for endurance runners, cyclists or anyone who wants to carry a very light load during their outdoor exercise. It comes in a variety of colors, and we love the inclusive size options. Still, there are a few drawbacks that make this pack a less ideal choice for some folks. If you’re running extreme distances or exercising for hours at a time in the heat, you may find that this pack simply doesn’t have the hydration capacity you require. It can hold roughly one liter of fluid between its two flasks. There is also the steep cost of this pack to consider, and some users say that with extended periods of exercise, the neck strap of this pack may begin to chafe. But for women looking for a well-fitting hydration pack, either for shorter periods of exercise or with plans to refill along the way, this is a great choice.

What we like:

• Lightweight
• Comfortable fit
• Lots of pockets

What we don't like:

• Very limited water capacity
• Neck strap may chafe
• Expensive

Best Hydration Pack for Running: North Face Summit Run Race Day Vest 8

Key Features:

• Price: $149
• Weight: 4.23-4.51 oz (size dependent)
• Gear Capacity: Eight liters
• Hydration Capacity: One liter
• Number of Pockets: Eight

Our choice for the best hydration pack for runners is the North Face Summit Run Race Day Vest 8. This ultra-light, comfortable pack lets you carry up to one liter of hydration without any extra weight or bulk. Its back panel sits comfortably without moving as you run. It includes a back pocket for trekking poles and front pockets for storing valuables like your phone and keys. It comes in five sizes so you can find the best fit for your body, which is all the more important for running, in order to avoid your pack shifting around or chafing. We love this pack’s breathable fabric and reflective highlights for visibility while running in urban areas or in low light.

One drawback of this hydration pack is the size of the front pocket; the pocket that seems to be designated for a cell phone may be too small to fit many devices. So if you have a cell phone that is particularly large, you might need to use a different pocket for phone storage. This light and capable hydration pack is an excellent choice for runners in many environments.

What we like:

• Five sizes and two color options
• Compatible with hydration bladder or water bottles
• Breathable fabric
• Pocket for collapsible hiking pole

What we don't like:

• Pricey
• Small phone pocket

Best Hydration Pack for Trail Running: Patagonia Slope Runner Endurance Trail Running Vest

Key Features:

• Price: $159
• Weight: 6.2 ounces
• Gear Capacity: Three liters
• Hydration Capacity: One liter
• Number of Pockets: Five

Trail running requires a daypack that is more durable than what you might need while running in urban or suburban conditions. For trail runners, we recommend the Patagonia Slope Runner Endurance Trail Running Vest. This small, slim pack includes two 500-milliliter Hydrapak flasks, which provides a total hydration capacity of about one liter. Made primarily for storing liquid and not much else, this pack comes with a gear capacity of only about three liters. But this lower profile and limited volume keeps the Slope Runner wonderfully light; this daypack is one of the lightest on our list at around six ounces. Some runners prefer to drink from a traditional water bottle style flask as they run, and if that’s true for you, this is a good option. Unlike some of the other hydration packs we’ve featured, this one doesn’t include a drinking tube attached to a hydration reservoir. Instead, you pull out one of the two flasks at a time and drink directly from it. This makes refilling and cleaning quick and easy.

The minimalist design is perfect for trail runners who want to carry only the essentials when they set out. It does include two small pockets for trekking poles, but its functionality is primarily with its hydration capacity and close-fitting storage. The Patagonia Slope Runner boasts a unisex design with four size options and a bungee-cord adjustment system; both men and women should find this hydration pack comfortable to wear. Some users find that the back pocket is difficult to reach while wearing the pack, but we think it’s a worthy trade-off for the extra space, which you could use to store a first-aid kit, for example. This hydration vest will keep you comfortable through long days of trail running. Like all Patagonia products, this hydration vest is made to last using partially recycled materials.

What we like:

• Environmentally friendly
• Available in four sizes for a fully customizable fit
• Comfortable

What we don't like:

• Back pocket difficult to access while wearing
• Water bottles may shift slightly when full

Best Hydration Pack for Long-Distance Running: CamelBak Ultra Pro Hydration Vest

Key Features:

• Price: $60
• Weight: Five ounces
• Gear Capacity: Six liters
• Hydration Capacity: One liter
• Number of Pockets: 13

We know long-distance and endurance runners need a hydration pack that’s super lightweight and comfortable. For these athletes we’ve chosen the CamelBak Ultra Pro Hydration Vest, which—at just five ounces—feels like wearing nothing at all. But make no mistake: This little daypack can hold up to six liters of gear and a liter of hydration solution amid its 13 pockets. The liter of hydration capacity is split between two 500-milliliter flasks, so if you prefer to carry two different types of fluid on long runs (for example, plain water as well as an electrolyte drink) this hydration system is compatible. Thirteen pockets provide plenty of space to stow away your phone, keys and other miscellaneous small items as you run, as well as any fuel packs or protein bars you choose to carry. This pack has reflective detailing, storage for trekking poles and a mesh back panel for air flow and breathability. The two water bottles included are CamelBak brand and covered by the product’s lifetime warranty.

We love that the CamelBak Ultra Pro Hydration Vest is available in three sizes. Its sternum and hip straps are adjustable, and the shoulder straps are lightly padded to avoid chafing. Users report that this bag is comfortable even on lengthy runs, and its extensive storage provides convenience without adding excessive weight. Some folks do find that CamelBak’s sizing runs large for this item, so make sure you keep that in mind when selecting which size to order. This is one of the best running hydration packs we’ve found for long distance runs.

What we like:

• Tons of pockets
• Three sizes
• Lightweight

What we don't like:

• Sizing runs large

Best Hydration Pack for Skiing: CamelBak Powderhound 12

Key Features:

• Price: $110
• Weight: One pound, 14 ounces
• Gear Capacity: 10 liters
• Hydration Capacity: Two liters
• Number of Pockets: Two

Skiing comes with its own unique challenges for hydration, fuel, gear storage and safety. For skiing and other winter sports, we recommend the CamelBak Powderhound 12. This hydration pack was made specifically for use in sub-freezing temperatures. The main compartment is protected with extra layers of fabric that repel snow and keep your supplies warm and dry. There’s also extra insulation around the two liter water reservoir and the drinking tube to keep your water or hydration solution from freezing while you’re exploring the backcountry on cross-country skis. External straps for storing your skis or snowboard while they’re not in use are a nice touch that give this hydration pack lots of versatility. This large pack can carry up to 10 liters of gear, like ski goggles, making it excellent for long trips where you want to pack extra supplies. It also features a removable stability belt that secures around your waist and a harness that allows for quick access on the ski lift.

This cold-weather daypack is available in one size and three colors. At $110, it’s firmly in the middle of the road cost-wise. Be advised that this bag is on the heavier side, weighing in at nearly two pounds. But with the extra insulation to keep your fluids and gear warm and dry, we think the weight and cost are both well worth it. This backpack is the best hydration pack to bring with you while skiing, snowboarding or hiking in below-freezing temperatures.

What we like:

• Water reservoir is insulated for use in below-freezing temperatures
• Large gear and hydration capacity
• External ski storage strap

What we don't like:

• Just one size
• Heavy, especially compared to other similar products

What is a Hydration Pack?

A hydration pack is a piece of gear that allows users to comfortably store their hydration on their body, allowing freedom of movement for the purpose of hiking, biking, running or other physical activity. Sometimes called a hydration backpack, this gear fits over the back and shoulders in a backpack or vest style, storing a flexible hydration reservoir or compact water bottles for easy access while on the move. Many hydration packs store water or other fluid away within the body of the pack to keep it from shifting around with vigorous movement; they may also include a water tube with a bite valve to allow for adaptable, hands-free hydration.

Hydration packs are a staple piece of gear for anyone who likes to exercise outdoors. They are a great way to carry water or electrolyte solution while keeping one’s hands free. Hiking, mountain biking, endurance running and skiing are just a few of the sports where athletes can benefit from carrying hydration in this way. If you find yourself frustrated and fumbling with your water bottle while you exercise, a hydration backpack may be just what you need to easily access hydration as well as store some extra gear.

Hydration Reservoirs vs. Hydration Packs

A hydration reservoir is the flexible flask or bottle that stores your water or other fluid as you hike, bike or run. These are often made with a durable, flexible plastic material to minimize extra weight and allow the reservoir to fit into small spaces. They often come with a water tube and bite valve system, which allows you to drink without opening a zippered pocket or fumbling with a loose water bottle. 

A hydration pack is a wearable piece of gear, such as a backpack or lightweight vest, that is made to hold a hydration reservoir. Sometimes a hydration backpack will also have zippered pockets and internal storage for other gear as well, like trekking poles, fuel or mobile devices. They are available in a variety of sizes, colors and styles. They may include a cleaning kit for your hydration kit as well. Whether you prefer something lightweight and minimalist, or a large, heavy hydration backpack with room for camping gear, you’ll find something that suits your needs.

How to Choose the Best Hydration Pack

Use

Which hydration pack works best for you depends on your typical use case. Consider how you plan to use your hydration pack. How often will you be using it? Do you have time to hand-wash your hydration reservoir or would you prefer something dishwasher safe? There’s also the matter of which sport or activity you’ll primarily be using your hydration pack for. Some hydration packs are better suited for some activities over others, and the fit of a hydration pack may limit what you can use it for.

Weight

The hydration backpacks we’ve shared range from an ultra-light five ounces to a much heavier two pounds. The difference between these two options can have outsize impacts on your athletic performance. If you’ll be on your feet, such as while hiking or running, you may want to choose something lightweight to minimize back pain and extra fatigue. If you’ll be mountain biking or bike commuting, however, a hydration pack with more storage space may be worth a bit of extra weight. And if you do choose a heavier pack, consider going with one that provides lumbar support to ease the strain on your back.

Size

We chose hydration packs that offer size-inclusive options, since athletes have a diverse array of body types. Size should be an important consideration with any gear that you choose, since anything ill-fitting can cause chafing and discomfort. Explore the size options and sizing guidance for each of these hydration packs to find a storage option that suits your body. If you aren’t sure which size to go with, consider choosing a hydration pack that offers adjustable sizing with bungees or customizable straps.

Additional capacity

Each of the hydration packs we’ve shared has capacity for both a reservoir and some other gear. Some have space for only a few key items, like a cell phone or extra fuel. Others pack in many liters of space that you can use to store camping gear, a first aid kit, trekking poles, a change of shoes or other necessities. More storage space usually increases the weight of a pack, so that’s a tradeoff you’ll have to consider when you debate which one to purchase. Remember the most common use case for your gear as well. If you plan to stick to runs around your neighborhood, you probably won’t need much extra space and can go with a lighter, slimmer option. Consider, too, the type of storage you need. Larger items will need to be stored in the body of the bag; smaller items such as devices or extra fuel can go in side pockets or mesh paneling on your vest.

How We Chose the Best Hydration Packs

We conducted extensive research to determine the best quality and highest rated hydration packs in the industry. We then categorized them for ideal use case based on features like gear capacity, weight and storage options. Our goal is to share a number of quality hydration packs, each of which has features that separate it from other options.

Final Thoughts

Whether you're mountain biking, hiking, training for your next marathon or hitting the slopes, these hydration packs will help you stay hydrated and allow you to carry your belongings hands-free as you exercise, no matter the climate or sport.
