Best Hydration Bladder

Geigerrig Hydration Engine

Geigerrig Pressurized Hydration Engine and Reservoir - 3 Liter, 100 Ounce

The Geigerrig Hydration Engine is our pick for the best hydration bladder roundup winner. The pressurized system and the sleek design pushed this hydration bladder to the top of our list. The more narrow design allows you to easily carry this system in hiking, backpacking, and running packs. You also get a double chamber that lets you choose between having a pressurized and unpressurized system. One slight drawback to the Geigerrig system is that once it’s full, the water does tend to move around quite a bit.

We also liked that you could flip this bladder inside out and it is dishwasher safe. All of the individual parts are easy to assemble and disassemble as well. This system is slightly more expensive than other hydration bladders, and it may be a little heavier if you decide to have it pressurized and carry the pump around.

Best Lightweight Hydration Bladder

Hydrapak Shape-Shift Bladder

HydraPak Shape-Shift Low-Profile Water Bladder/Reservoir for Hydration Backpacks, 3-Liter (100 oz.), High Flow Bite Valve, Safe & Reliable

The Hydrapak claims our runner-up spot, and if you’re looking for a hydration bladder that can give you an exactly fluid-ounce count on your adventures, this is it. The simple design and the slim profile make this an excellent hydration bladder for racing or smaller packs. It can hold up to being frozen or laying in the direct sunlight with no issues.

The zip-lock closure stops your water from moving around too much as you move, and the wide-mouth flip top opening makes it easy to clean and dry. It is also dishwasher safe, and you can turn it inside out for a complete clean. The locking mechanism does tend to stick if you use sugary drinks, and it doesn’t come with a handle so filling it in shallow spots can be difficult.

Best Value Hydration Bladder

CamelBak Crux Hydration Reservoir

CamelBak Crux 100 oz Hydration Pack Reservoir, Blue

The CamelBak Crux won the category for the best value for your money due to the fact that it’s extremely easy to fill and use, and it’s one of the least expensive bladders on our list. It’s also backed by a limited lifetime warranty, and this works to enhance the long-term value it has. If you’re looking for a quality hydration bladder on a budget, look no further.

You’ll get a large handle that makes it easier to fill and hold, and the bite valves are very secure and medium-sized. This hydration bladder may take more time to clean, especially if you use other liquids than water. It is also slightly heavier than its predecessors, and this is something to keep in mind.

Looking for the Best Hydration Bladders?

You’re in the right place! In this guide, we will be covering the following:

    • Why you need a hydration system
    • What you should consider when buying hydration bladders.
    • Reviews of the best hydration bladders on the market
    • Our unbiased recommendation on the best hydration bladder for hiking

For the avid outdoor enthusiast or someone who likes to go hiking on weekends, a hydration bladder is a must-have piece of equipment. They’re an excellent alternative to carrying water bottles around as they’re usually lighter and easier to drink from. A hydration bladder lets you drink your water while you’re moving, and you don’t have to stop and pull out your water bottle.

As hydration bladders are gaining in popularity, may hiking packs, backpacks, and running packs now have a pocket for your water bladder. You can choose from dozens of shapes, designs, and bonus features to customize your water bladder to your needs. But, how do you choose the correct one? We’re going to go over the criteria you want to look for in your hydration bladder, and we’ve rounded up 11 of the top bladders to review.

Hydration Bladders Buyers Guide


The first thing you should consider before you buy is its size and its compatibility and whether or not it’ll fit in your backpack’s compartment. Although most hydration bladders are roughly the same shape, it’s the size that sets them apart. You’ll typically find two-liter and three-liter sizes, but they do make one-liter and 1.5-liters as well. 

In general, most people go for the three-liter sizes because you get around twice as much water as a one or two-liter model for around the same price. This gives you the flexibility to fill your bladder up completely or only part way depending on what your plans for the day are. One of the main reasons you wouldn’t want a three-liter model is if you have limited space in your specific pack compartment. If you do a lot of trail running, your running pack may only have a maximum of two-liter capacity. Take a look at our sizing guide to get a better idea of which bladder will suit you the best.


The profile is another important consideration. You can purchase models that have a wide profile, or some have a narrow profile. When you fill them, some are flat while others expand and get fat. Before you settle on any specific model, look at your Hydration Pack and its dimensions. Most packs that are compatible come with a hydration sleeve that is built-in. Check how narrow or wide your hydration sleeve is, and this will give you a good idea about which hydration bladder to buy. 

Pressurized or Non Pressurized

A pressurized hydration bladder will have two separate chambers with one for water and one for air. You use a pressurized pump to blow air up into your hydration bladder so you end up with a bladder of water that you can access without sucking on the mouthpiece. They’re generally considered to be easier to clean, easier to use, and you can go longer between cleaning systems.

Bite Valve Size

Hydration bladders have bite valves that allow you to get your water out of the bladder, and many vary in size, and some also have a type of locking mechanism to prevent leaking. Your bite valve’s size directly affects how difficult or how easy it is to get water by sucking from the tube. Generally speaking, larger bite valves are more difficult to suck water through if you don’t have a pressurized system. Smaller valves are easier to suck through, but they usually don’t give you the larger flow you’d get from a medium valve. 

Locking Mechanism

If your bite valve comes with a locking mechanism to prevent leaks, it’s usually one of two types. You’ll have either switch locking mechanisms or a turn mechanism. The switch valves are usually easier to clean and operate one-handed because they’re less prone to sticking as the switch itself doesn’t usually come into contact with your liquid of choice. Turn valves can be more difficult to operate one-handed because they tend to stick due to buildup or sugar reside. 

Cleaning Ease

Almost all hydration bladders have some small area that is very difficult to clean and dry properly, and this can be the perfect place for bacteria to grow. If you intend to use one solely for H20, you won’t have to clean it as much because there isn’t a residue left behind. But, if you use liquid with sugar in it, you’ll want to clean your hydration system out after each use because the residue will build up and be a breeding ground for bacteria.

It can also affect how your drink tastes the next time you use it. You’ll focus on cleaning the bladder itself, the tube, and the mouthpiece as they see the most use. 

Pro-tip: Ease of cleaning is the single area that your wide mouth screw-top water bottle wins over even the best hydration bladders.

If it’s possible, look for a model that has a wide mouth so you can easily fit a brush inside to reach everything, or you can flip it inside out to clean and dry it. Also, make sure it’s easy to take the hose and mouthpiece apart so you can clean every part of them.

A quick-release hose is great because it lets you disconnect the tube from the bladder quickly and easily to clean it or swap parts out. If it doesn’t have a quick-connect mechanism, it’ll be more difficult to clean the hose thoroughly. Generally, a flip-top model that you can turn inside out and put in the dishwasher is the easiest to clean completely. 

Compatibility of the Hoses

Ideally, you want the tube to have a connection mechanism that is vertically oriented. Some model’s hoses are horizontally oriented, and they have specific attachments. This limits what hoses you can switch out and use with your bladder. If your hydration bladder has a connection mechanism that is compatible with other hoses and attachments, but it has a horizontal orientation while others have a vertical orientation. If you try to switch out your hoses to a bladder that has a vertical orientation, it’ll stick out to the side instead of sitting up and down. This can create an issue with the durability, and it can shorten its lifespan. 

Choosing a Bladder Style

Filling up is another significant consideration you have to keep in mind when you’re shopping for a new bladder. Things like how easy it is to fill, the environment types you plan to fill it in, and how easy it is to open and close all factor in. You have the choice of a zip top, screw top, or a fold top. 

Fold Top

The top of a fold top style model flips up and folds over. When you fold it over, you slide a think closing mechanism over the fold to secure it closed. The opening is usually fairly wide, which allows you to easily fill them from your tap, shallow streams, or areas with limited water sources. The opening itself has a very slender profile, so you don’t need deep water to fill it properly, which is a huge advantage in areas where you have limited resources. Additionally, you can usually turn this type inside out to clean and dry it easier because you can reach everything with a brush or with your hand.

Zip Top

The zip-top hydration bladders are very similar to the fold top hydration bladders. The tops of these bladders look like a large zip-lock bag that your press close and slide a closure over the top of the zipper portion. The openings in these bags are also fairly wide, and they have a lower profile, so it’s easier to fill them in slow-moving streams or at home under the tap. These types of bladders are slightly harder to clean than the fold top styles because you need a brush to clean the inside, and you usually can’t flip them inside out to reach everything. 

Screw Top

Models with screw tops do take slightly longer to open/close, but they’re one of the easiest types to fill in shallow water. You hold these water bladders either horizontally or vertically to fill them, and this allows you to quickly and easily fill them in a water fountain or from the tap. This is a significant bonus if you’re trying to fill it up in a public restroom where you don’t necessarily want your bladder touching more than necessary. Additionally, you can fill screw-top hydration bladders completely, where you may have to leave a slight space with the fold to zip tops to close them properly. However, these models may be slightly more difficult to clean because you can’t turn them inside out and it can be harder to get your brush inside to reach every small area.
