Best Hydration Bladder
Geigerrig Hydration Engine
The Geigerrig Hydration Engine wins our vote as the best hydration bladder out there this year. This tidy, versatile little piece of kit does it all. It’s lightweight, packable, leakproof, and uses dual chambers that allow you to use it as either a pressurized or unpressurized system.
Many factors pushed this item to the top of our list. The most notable, however, are its sleek, space-saving design and overall versatility.
The streamline design allows you to carry this bladder in hiking, backpacking, and running packs with ease, while the dual-chamber, pressurized system makes it easier to drink from both while you’re on the move and around camp.
The Geigerrig also boasts a wide-mouthed opening that makes refilling a cinch. And the slide-top closure also makes it less prone to leakage than the screw-top varieties used in many other models.
We also liked that you can flip this bladder inside out for easy cleaning, can disassemble and reassemble it in seconds, and its dishwasher-safe design. All of these features might seem like trifles, but they go a long way in boosting the bag’s overall convenience.
This one’s a little heavier than some of the other products we’ve reviewed, granted. But those extra few ounces translate to added ruggedness, puncture-resistance, and durability, all of which combine to make this one of the most trail-worthy H20 carriers out there.
Bottom line: Reliable, versatile, convenient, and as practical as they come, the Geigerrig Hydration Engine an outstanding choice for outdoor activities like trail-running, mountain biking, hiking, and camping alike.
For those who prioritize convenience and portability, there are few bladders out there that can lay a glove on the Hydrapak Shape-Shift.
With many bladders, once you’ve supped the contents halfway down, the remaining contents are apt to slush around. This not only feels kinda weird but could, in some cases, also throw you off balance, especially when moving fast.
Not so with the Hydrapak Shape-Shift! This tidy little reservoir uses an adjustable baffle that helps you ensure it maintains a low-profile when filled with less than the full 3 liters and also increases stability during high-impact activities.
Other endearing features on the Shape-Shift include a printed fluid-ounce count on the side that helps you make sure you’re drinking enough water, a slim profile that lets it fit snugly inside even smaller packs, and freeze-resistant materials that prevent blockages in cool temps.
This bladder also boasts a wide-mouth, flip-top opening that makes it easy to clean and dry, has an auto shut-off valve to prevent leaks, and uses a “plug-n-play” system that simplifies refilling and in-line filtering.
Although a fraction more difficult to use due to the lack of a handle, otherwise it’s a winner!
Bottom line: A simple but highly practical, well-designed, medium-sized bladder. Short on bells and whistles but a perfect choice for trail-running or hiking daypacks nonetheless.
The CamelBak Crux is not only one of the least expensive systems on our list, it’s also one of the easiest to fill, most reliable, and least likely to leak as a result of punctures or tears.
As with all things CamelBak, the Crux oozes quality in every component. From the fast-flow, “big bite” valve and twist-open closure cap to the burly, confidence-inspiring materials, CamelBak have gone the extra mile to make this one a truly high-performing, trail-ready piece of kit.
This system also uses an intelligent, lumbar-style design. Unlike rectangular bladders, this design means the weight of your water is shifted to your lower back, thereby giving you more stability on the trail and helping to improve balance.
Other lovable features included in the Crux include a large haul handle that makes it easy to refill, a self-sealing, drip-resistant valve, and a mightily handy on/off lever that lets you seal the drinking tube with one hand.
While the Crux can’t, like other bladders in our review, be folded inside out for easy cleaning, it uses HydroGuard technology that prevents the growth of bacteria in both the reservoir and tube. So, even if you’re a little lax with post-hike cleaning, you won’t have to worry about your H20 becoming a breeding place for tummy-troubling microbes.
Bottom line: An intelligently designed, robust, and hardwearing hydration system that performs just as well, if not better, than most of its far pricier peers.

Reviews of the best hydration bladders on the market
Our unbiased recommendation of the best hydration bladder for hiking
Whether you’re an avid outdoor enthusiast or only take to the trails once in a while, a hydration bladder is a must-have piece of equipment.
But what is it that makes a bladder a better pick than a regular, old-fashioned bottle?
Well, in addition to being lighter, more compact, and easier to clean, hydration systems boast one standout feature that makes them ideal for outdoor adventures:
Streamlining and speeding up the whole process of getting your ample fill of H20.
While drinking from a bottle entails having to stop, open your pack, pull out your bottle, unscrew the lid, and then do it all in reverse before you can get moving again, a hydration bladder lets you do your drinking on the move, hands-free.
Not only does this ensure you’ll stay hydrated while getting your wander on, it also means you’ll spend more time enjoying your surroundings and less time taking care of practicalities.
But, how do you choose the best hydration bladder for your needs? Well, we’re here to help. Below, we’ll take a detailed look at what goes into the making of a great hydration bag and follow that up with honest, unbiased reviews of the top bladders on the market.
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.
1 or 1.5 Liter – This size is perfect for commutes, kids, and short hikes or runs because you won’t need much aqua and it’s lighter to carry around. It’s also a good choice if you know you can refill it often while you’re out and about.
2 Liter – If you do a lot of day trips, skiing, snowboarding, or hiking, consider a two-liter model. This will give you a decent amount of H20 to sustain you throughout the day, and it’s a great option if you’re not a fan of constantly refilling it.
3 Liter – If you don’t plan to fill up on your trip unless you can’t avoid it, this may be the perfect size for you. It gives you the option to carry smaller amounts of water, or to fill it completely. This is perfect for long trips, camping, or hiking places where H20 is scarce.
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.
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.
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.
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.
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.
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.
Frequently Asked Questions
How Much Water Should You Drink in a Daily Basis?
If you’re doing endurance activities, you want to try and drink between 17 and 25 ounces of H20 every hour. For most activities, you should try and drink between 18 ounces per hour, and more if it is hot and humid out. If you’re not sure, check this hydration guide.
How Do You Clean Your Hydration Bladder?
To start cleaning and drying, get very hot water and add a little bleach along with two tablespoons of baking soda. Make sure that the solution runs throughout your water bladder, and leave it to soak for 30 minutes. When the 30 minutes is up, rinse thoroughly and take a small brush and scrub the insides and around the hose connectors and mouthpieces. Leave it to air dry completely, turning it inside out if it’s possible.
How Often Should You Clean Your Hydration Bladder?
This largely depends on how often you use your bladder as well as what you put in it. If you use it with sugary drinks, you want to clean it thoroughly after every use. If you just put water in it, you can clean it maybe once a month.
Can You Buy High-Quality Hydration Bladders Online?
Yes, you can purchase high-quality models both online or in many sporting goods stores. You can even buy them straight from the brand’s website for added convenience.
Do You Have to Drink Just Water?
No, you can use any liquid you like. However, any strong-flavored drink you use may leave a taste residue behind. Also, sugary drinks mean you’ll have to clean more often to prevent buildup.
