Our Verdict

Looking for a durable yet straightforward hydration bladder? The Deuter Streamer is a perfect system for on-the-go hydration. We took it hiking, running, biking in the desert and through the San Juan mountains in Colorado. It's easy to fill, easy to use, and super easy to clean. Also, we love that when empty, it rolls up nicely for easy storage. This is a fine all-around use bladder with decent durability. That said, some of the parts are made of a flimsy and cheap plastic that proved to have shoddy craftsmanship in our quality tests.

The bite valve is unique with a different design that is comfortable in the mouth, but offers less water flow than valves designed by HydraPak such as in our Editors' Choice winner, the Geigerrig Hydration Engine. Also, while the flip-top design allows for easy filling, it's not as long or as heavily featured as the Osprey Hydraulics. If you seek a bladder with a bit better performance, the Source Tactical WXP has more features than the Streamer and is constructed with the same materials. It is a little more versatile, but has a different bite valve, and costs a little more. Overall, the Deuter Streamer is a great choice if you seek a simple hydration bladder with a unique bite valve and a more puncture-proof reservoir.

Our Analysis and Test Results

The Deuter Streamer is a no-frills hydration bladder that is perfect for on-the-go sports. It features a heavier plastic construct which offers better durability, but the use of poor quality parts makes it seem cheap. That said, it functions well and does the trick on the trail.

Ease of Use


With a simple design, this slide-top bladder design is easy to use. The closure at the top features a hole to suspend it from clips that hold the bladder in place. While this closure is okay, it takes a little longer to line up the plastic to securely fasten the top. Also, it is not connected to the bladder, but that can be fixed with a little bit of string.

Alison fits the 3L Deuter Streamer into her small running pack. Even though the pack is built to hold a 2L bladder  the 3L option doesn't need to be filled the whole way and offers a little more versatility for use in other packs.

Its slim profile fits nicely into most hydration packs, running vests, and backpack sleeves. The bite valve is different than most, offering a smaller stream of water that shoots out with a little more pressure than other bladders. While we appreciate this difference in design, this it doesn't provide as much water as those manufactured by HydraPak. To unlock it, it must be twisted which requires two hands, and the cap must be removed. This takes a little more time than other options. When we left it unlocked while hiking, it didn't leak.

Some of the Source made bite valves found in the Deuter Streamer and Source tactical has a cap that comes with the design.

The hose is interchangeable with other models  like the Source Tactical and the bladders designed by Hydropak.

There is a plastic cap that covers the bite valve which bangs against the body when in motion if not properly secured. We would prefer that it didn't exist as we can't see the real function of this cap other than hygiene. Sadly, if you don't like this bite valve, you're stuck with it as it can't be removed from the hose. However, you can change out the hose with pretty much any other option in this review. One notable feature that we really like is the high-quality clips that secure the hose to the bladder. We like this design as it makes releasing the hose easier, and it doesn't get gummed up like other competitors. Overall, it's an all-around bladder that is relatively easy to use.

Ease of Care


The slide-top opening allows you to access all parts of this bladder and turn it inside out. The hose disconnects at the base of the bladder. The heavier film used is less-porous than other thinner films, which helps to avoid bacterial build-up. While it is not dishwasher-safe, it is easy to maintain. Make sure to blow all water back through the hose and empty after each use. Put it in the freezer to ensure no bacterial growth between uses.

Ease of Filling


The slide-top opening is large enough to fill from a tap, lake, or stream. While the slide-top opening isn't as elongated or as heavily featured as the Osprey Hydraulics, it certainly has the affinity to collect water from small trickling streams. Lay it down flat to collect water when there isn't a lot around.


Quality and Durability


Not the most durable bladder out there, we are not the happiest with the quality of some of the features. While we appreciate the thicker film that makes it more impervious to punctures, the seams at which the plastic holder connects started to delaminate almost as soon as we pulled on them during our quality tests. That said, we didn't observe any leaks or issues with other parts of the bladder in our testing period.


We didn't observe any issues with bad taste right out the box! Score!

Weight and Compressibility


The heavy plastic film used in this bladder's construction makes it a heavier hydration bladder, but still useful for sports that require a lightweight design. When emptied and the hose is disconnected, it rolls up nicely into a nice, neat package that fits easily into the side or lid of a backpack.


Best Applications


A wonderful option for hydration on-the-go. Take it hiking, backpacking, biking, running, or more! It will function well for pretty much any sport, offering a higher level of protection from punctures than other lightweight options out there.

Use this hydration on the go! Take it running  hiking  biking  and more! Its versatile  lightweight  and durable to punctures.

Value


Retailing for $34, this bladder sits in the middle of the road for the price. This isn't a high-value option, but if you're seeking a bladder that is a little more durable and versatile, this may be a great value for you.

Conclusion


The Deuter Streamer offers hydration for an array for outdoor sports. We love its bomber exterior that provides additional protection from punctures and tears as well as its easy-to-use construction. A great option for hiking, biking, running, and more.
