This is a very popular two-liter hydration bag. It has a relatively large screw-cap gap that is leak-proof. The bag is made of TPU and the material has been tested and approved by the FDA to be non-toxic. The hose is long and insulated so the bladder is great for winter use too. You get a cleaning kit and two replacement bite valves as a gift. On top of this, it is very affordable too.

It comes with a 100% money back-guaranteed policy if you are not satisfied with the product. The bite valve in this hydration bladder is anti-bacterial, sturdy, and soft. It is made from high-grade Silicon.

The large opening of the reservoir makes it easier for you to add ice to your water. You will definitely be refreshed throughout your outdoor activity. The easily accessible shutoff valve makes it leak-proof and prevents water from dripping when stored in a non-vertical position, and while doing vigorous activities.

  • Sometimes there is a leakage in the end attached to the bite valve

3. Source Widepac Hydration Bladder

Source Widepac Hydration Bladder

Available in three completely different sizes of 1.5L, 2L, and 3L, source Widepac hydration bladder is without a doubt one of the most effective water bladders.

It is constructed from the favorable coextruded polyethylene and features a glass-like liner inside of its reservoir and tube. This technology, apart from putting at bay the loathed plastic taste in water, also confers the self-cleansing ability to the reservoir. As such, bio-film buildup and bacterial growth in the reservoir are effectively deterred.

Its rounded helix bite valve features a safety shutoff mechanism that completely prevents leakages even under pressure or with prolonged use. Biting it softly delivers a sufficient flow of water into your mouth. The dirt-shield protective covering protects the bite valve from dirt and other forms of physical contamination.

A technology that utilizes FDA-approved and EPA-registered anti-microbial agent effectively inhibits bacterial growth inside both the reservoir and the suction tube. This agent lasts the entire lifetime of the bladder. Therefore, if your health is of great concern to you (we think it should be), this is the reservoir meant for you.

Several options allow the low maintenance of the Widepac reservoir to be possible. First off, its glass-like film liner, smoother than standard TPU films by about 2000% (20 times), makes it self-cleansing. What this means is that you can confidently refill this reservoir repeatedly before you can finally clean it. Your water remains fresh for several days.

The Widepac wide fold-top, made in a way that enables easy refill, ice-insertion, and makes cleaning an easy chore. The high-quality slide-closure puts prevent leaks from happening.


  • BPA free material
  • Keeps water sterile and usable for a long period
  • No taste nor odors
  • Easily to be maintained


  • The size of the suction valve is relatively huge
  • Some users complain about the placement of the hanging point at the top slide bar

4. Deuter Streamer 2.0 Hydration Bladder

Deuter Streamer 2.0 Hydration Bladder

Made of thick polyethylene material and coming in sizes of 2 liters and 3 liters, the Deuter Streamer hydration bladder offers an odorless flow of water that will see you stay hydrated throughout your hikes for more than just a couple of years. Now we all hate that putrid taste of water stored in those hydration bladders made of polyurethane.

One striking feature about this hydration bladder is the location of the quick connect for the hose. Right at the base of the bladder, the quick connection will enable an extended flow of water until the bladder is almost empty. This is unlike most other hydration bladders, which have the hose connector at about one-third of the distance from the base.

The bite valve is just about the perfect size and has a nicely fitting removable cap for deterring dust and other contaminants. Therefore, your water is kept sterile and you open the valve only when you want to sip the water. The twist-to-lock valve, together with the closing cap, ensures the absolute absence of leaks via the mouthpiece.

Even then, some people hate the fact that one has to remove the bite-valve cap every time they want to sip from the bladder. I am not one of those people since I value my health more than comfort.


  • Odor and taste-free water
  • Easily to clean and dry
  • Leak-Proof Design
  • Can be used even with a small amount of water


  • Every time you need water, you have to open the bite valve and then close it
  • The plastic clip is not very durable

Free of BPA and BPS, this water bladder has maintained its high ratings and positive reputation. Several quality-enhancement features have been carefully crafted into the CamelBak and you will be buying into nothing short of a proven hydration system.

Over time, CamelBak has been modifying its hydration bladders in response to feedback received from users worldwide. The CamelBak Antidote Reservoir is the newest of their reservoirs that date back years ago.

Compared to the older versions, the newer Antidote has an array of performance-enhancement features that see it outperform its predecessors in several ways. Its wider mouth gap, together with its larger grab handle, enables easy refilling and cleaning. Its baseline hose connector allows complete draining of water from the reservoir.

The two water chambers are a clever feature that, apart from welding the bladder into a slim-profile reservoir, reduces the sloshing of water within it. Other further features include a removable hose, integrated foldout dryer arms, and a Quick Link system, which makes changing the reservoirs seamless.

First off, this hydration bladder comes in sizes of 2 liters and 3 liters each featuring a combination of both the screw cap and the fold-top design for opening and closing. Both of these closures are watertight and leak-proof.

Since this feature caters to both preferences, it has seen the WXP so quickly rise the popularity scale to become a favorite of a wide group of hikers and outdoor-savvy individuals.

The interiors of the reservoir and tube feature a glass-like liner, which serves a crucial role of acting as a mechanism to prevent biofilm build-up, which in turn prevents bacterial growth in the reservoir. Additionally, this liner prevents the kept water from developing plastic flavor.

The WXP is further enhanced with Grunge-Guard antimicrobial technology that prevents bacteria and other microorganisms from thriving. This technology encompasses an anti-bacterial agent that is permanently embedded into the inner walls of the reservoir and its tube, to last the entire lifetime of the hydration system.

7. Badlands Hydration Reservoir

Badlands Hydration Reservoir

Specifically designed for hunters, the Badlands is both convenient and reliable. It is a spectacular product whose birth was a result of the collaboration between Hydrapak and Badlands.

It is sturdy, leak-proof, practical, and quieter than any other water reservoir out there. Constructed with 0.25mm thick Thermoplastic Polyurethane (TPU), the Badlands is available in 3 different sizes of 1L, 2L, and 3L and rectangular and square shapes.

Durable but lightweight and with a perfect length, the Badlands TPU hose is remarkable in two ways. First, the Plug-N-Play™ tube connector lets you easily attach and detach the tube from the reservoir. This, apart from enhancing the flexibility of the bladder when cleaning, also allows for easy refills.

Secondly, the hose sports a built-in foam insulation mechanism, which keeps water within the tube colder for longer. If you have ever sipped warm water during blistering-hot temperatures, then you know why this Hydrafusion™ insulation technology is a great feature of this reservoir’s drinking tube.

The Elite Surge Valve permits lots of water to flow into your mouth with easy suction. To keep the bite valve sterile, a freely dangling dirt cover is connected.

  • Lifetime warranty
  • Durable product
  • BPA and PVC free material


  • It is not see-through
  • Water has a rubbery taste at first then it dissipates over time

9. Geigerrig Hydration Engine

Geigerrig Hydration Engine

The only pressurized hydration bladder we have tested, Geigerrig performs stunningly and is the most reliable. Its most striking (and indeed innovative) feature is the pressure system. It has an ellipsoidal air pump that looks like that one you find in the old-school blood pressure machines. This pump connects to the reservoir’s air compartment.

Pumping it fills the air compartment creating a pressure that forces the water to squirt out through the suction hose. Thus, not like the other water bladders which require suction and propulsion of water into your mouth, Geigerrig does the pushing for you.

Initially, the Geigerrig was designed for tech-savvy outdoor adventurers. Its popularity over the years has however proven that it indeed is a favorite of everyone; both the tech-savvy and the ordinary outdoor lovers.

Sufficiently leak-proof, Geigerrig is designed of sturdy TPU and is BPA-free. It is a zip-top reservoir that opens full-width like a pouch and comes in three different capacities of 1.5L, 2L, and 3L.

Still, its three different capacities of 2L, 2.5L, and 3L are a great versatility feature that offers many choices to its users.

When you initially place your hands on the Unigear water reservoir, the one thing that will instantly strike your attention is the super-comfy, lightweight material it is made of. The food-grade Thermoplastic polyurethane (TPU) has a flexible feel, is BPA-free and FDA-approved.
