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.
