In situations where a water bottle just isn’t enough, a hydration backpack gives you direct access to much-needed fluids on the go. Like a regular backpack, only better, there are a ton of different hydration-based backpacks to choose from.

Why Use a Hydration Backpack?

The main purpose of using a hydration backpack over other kinds of baggage is to make staying hydrated convenient and efficient, no matter what you are doing. Experience more without having to worry about stopping to take a drink, and keep up your pace without slowing down.

With a built-in water reservoir, you can take regular sips through the drink tube to ensure that you are in top form at all times. Different packs are designed to suit some activities more than others, so be sure to do your research before you dive in.

Often used by the military on extended ops, hydration backpacks have been keeping outdoor enthusiasts well-watered for many years now. Some of the most popular uses for carrying a hydration backpack include running, hiking, cycling, kayaking, and just about any outdoor sporting activity you can think of.

Bottom Line: With enough room to carry extra essentials like a change of clothes and personal items, a hydration backpack is the only vessel you need to enjoy hands-free adventures, whatever the weather.

Things To Consider With a Hydration Backpack

A hydration backpack offers a heap of potential benefits over a regular daypack, but you will need to take good care of it and make sure that it is:

Easy To Clean

Because you will be drinking directly from the backpack reservoir via the drinking tube, your backpack needs to be super-easy to clean so it remains mold-, mildew-, and bacteria-free.

Hydration bladders that are easy to fill are usually also the easiest to clean, as they offer better accessibility to every last inch of the reservoir. A quick rinse may suffice on a day out in the open, but your backpack will need thorough scrubbing back at the base to prevent nasty-tasting water on your next trip.

Bottom Line: Ease of cleaning is an essential aspect of how good your hydration backpack is. After all, you wouldn’t drink water from a dirty glass, would you?

Easy To Drink

Hydration Backpack Easy to Drink

Different backpacks offer varying flow rates, straw lengths, and spouts, and your preferred outdoor activities will dictate which type of drinking system works best for you.

The main choices for how to drink your water on the go are bite valves or push-pull valves. With a bite valve, you simply apply pressure with your lips or teeth to drink water completely hands-free. With a push-pull valve, however, you will need to twist and pull the valve to release the water.

Bottom Line: No matter what outdoor activities you are planning to get stuck into, hydration backpacks still offer the easiest and most efficient, hands-free way to take regular sips while you are busy doing something else.

Easy To Fill

Filling Hydration Backpack

To feel the full benefit of your new hydration backpack, it is imperative that you can fill it up when it gets empty, and this is easy to do. While different designs may require different techniques, once you get the hang of how to do it, you shouldn’t have any problems at all.

You will usually need to take the bladder out of the backpack and fill it up using a regular faucet or a water bottle with a funnel. You will need to fill it to its maximum capacity before screwing the lid back on and inserting it back into your backpack.

Bottom Line: Hydration backpacks should make your life easier. You should also make sure that the bladder is full and inserted back into the backpack before you fill it with the rest of your personal items.


Hydration Backpack Comfort
Hydration backpacks shouldn’t move around too much. Image Credit: Amar Hussain

Your hydration backpack should fit you like a glove. While you are running, hiking, cycling, or whatever else, it is vital that your backpack fits the curves of your body and that it doesn’t bump and jump around too much, even when you do.

Your backpack should be an appropriate length for your torso and grip you well around the hips. Different models come in different sizes, and you should find one that fits precisely before you commit to buy.

You can also buy hydration backpacks that have been designed to specifically accommodate the size and shape of the female torso, as well as those that are made for teenagers and younger outdoor enthusiasts.

Bottom Line: Whatever activities you plan to use your hydration backpack for, make sure it is comfortable, adjustable, and the right size for your frame. 


Hydration Pack Sizes
Hydration backpacks and bladders come in a variety of sizes. Image Credit: Amar Hussain

The backpack you choose should have enough capacity in the reservoir itself to ensure that you have enough water to keep you going for a couple of hours at the very least. It should also offer the ability to fill it up on the go, in case you delay your return or simply need more water.

As for the overall backpack, most hydration packs offer enough space for the basics, such as a bike pump, keys, wallet, phone, and other small essentials. Some will have additional hanging loops, compression straps, and more interior space, but most do not offer the same level of storage capacity as a regular daypack will.

Material and Durability

Hydration Backpack Material

Because your hydration backpack will have been explicitly designed to keep you hydrated on the go, it will also have been created with weight, profile, and durability in mind. The most effective hydration backpacks are made from lightweight, water-resistant material — usually nylon — and may offer additional features to increase comfort.

Bottom Line: Padded straps help you to wear your backpack for longer, while breathable mesh fabrics will keep you cool, even when the sweat starts to pour.

Storage and Organization

Hydration Backpack Compartments
Hydration backpacks have lots of handy pockets. Image Credit: Amar Hussain

The most important feature of your hydration backpack will be the water reservoir — also referred to as the bladder — and the drinking tube that goes with it. These main elements are kept in a separate compartment from any other items you wish to carry with you, and they will need to be removed for easy cleaning when the time comes.

Other than this, the amount of space you can use for transporting your regular essentials will depend very much on the size of the backpack you invest in.

Bottom Line: At a minimum, most smaller backpacks should still offer a front pocket and some internal storage space, while a bigger backpack could easily offer pockets, zipped compartments, lash points, helmet loops, and even compression straps.

The 6 Best CamelBak Backpacks

Any review of hydration backpacks would not be complete without a nod to the brand leader Camelbak.

The 7 Best CamelBak Alternatives

CamelBak may be the most famous name when it comes to external hydration, but is certainly not the only brand out there that makes affordable, high-quality solutions for adventurers on the go. Here is a selection of the best CamelBak alternatives:

1. A 2-Liter Reservoir Makes for Easy Hydration on the Go

TETON Sports Oasis 1100 Hydration Pack
This lightweight option features a 2L water capacity. It's an excellent choice for outdoor day trips and is highly durable. The comfortable design is adjustable and made from mesh and a notched foam stabilizer.

Teton Sports Oasis 1100 Hydration Pack

The Teton Sports Oasis comes in a choice of 1100 or 1200, and both sizes are incredibly popular daypacks and a viable alternative to a CamelBak bag. Large enough to carry everything you need on a day trip or short break, the removable BPA-free hydration bladder will keep you hydrated wherever you go.

With a durable, hard-wearing sip tube, push-down lock, and cushioned bite valve, the bladder is easy to drink from and easy to clean. For carrying your extra essentials there are several dividers to keep your belongings organized, and the built-in rain cover will keep your gear dry.

Made from durable honeycomb ripstop material, both the 1100 and 1200 models are highly water-resistant and have reflective loops to keep you safe in low light. With adjustable shoulder straps, a chest strap with a built-in whistle, and hydration tube straps, you can adjust the pack to meet your individual requirements.

Osprey Packs Raptor 14 Hydration Pack

Osprey has a reputation for producing high-quality activity-specific backpacks that are well-thought-out and incredibly durable. The Raptor 14 is, without a doubt, one of the best in the range and works well for practically any activity. From mountain biking and extreme sports through to your daily commute, this pack can handle it all. It has been designed to fit the male frame, and Osprey also makes the same pack suited for the female frame in the Raven 14.

With enough room to comfortably carry your tools, snacks, spare clothing, phone, keys, wallet, and other essentials, this is a very worthy backpack even without the hydration system. But, with an impressive 3-liter hydraulics reservoir, a bite valve magnet clip, and a bladder that always retains its shape to avoid sloshing when you are riding, this backpack rivals the CamelBak eloquently.

Made from tear-resistant 70x100D nylon fabric, and designed to be incredibly comfortable and lightweight, there are plenty of comfort features added to this backpack.

While there is a small front pocket for your belongings, space is limited, and it can only hold a smartphone, keys, and a snack bar or equivalent. Inexpensive and great for those looking for a high-speed alternative to a water bottle, this little backpack will undoubtedly do the job.

What We Like

Frequently Asked Questions

How much water can a CamelBak hold?

The size of the CamelBak backpack does not necessarily dictate how much water it can hold — the size of the water reservoir does. CamelBak has 3 different reservoir sizes: 1.5, 2, and 3 liters.

Are CamelBak backpacks made in the USA?

CamelBak products are manufactured in the U.S. and China.

Does CamelBak have a lifetime warranty?

CamelBak products come with a Got Your Bak Lifetime Guarantee that covers manufacturing defects only. Normal wear and tear, improper use, or negligence is not covered by the guarantee.

Are CamelBak bladders BPA-free?

CamelBak’s reservoirs are free from BPA, BPS, and BPF.

Can you put a hydration pack in a regular backpack?

You could use a hydration pack inside a regular backpack, but without a built-in reservoir, your hydration pack would move around inside the bag. Some bags come with specific interior sleeves that can hold a reservoir, which may be more suitable, especially if you’re moving around a lot.
