    Great Hydration Reservoir for backpackin

    • Familiarity: I've put it through the wringer

    Wow...the Platypus Big Zip EVO 3.0 Liter performed great on my 2 week backpacking trek to Philmont Scout Ranch this past June. In fact, I was able to drink our good city water the first 3 days before I had to fill it up again. I have used other reservoirs before and some can easily leak or come "unzipped" at inopportune moments. Not the Platypus! It performed like a champ. Not a single leak the entire two weeks and the water tasted great the entire time. Great flow rate once you bit down the right way on the bite valve. And what was really great was the volume of water I could carry that stayed cool the entire time. With 3 liters insulated by camping gear, and temps at night in the 40's, I enjoyed cold water each day. Unlike what I would have experienced with water bottles that heat up quicker. I would highly recommend this reservoir. It is very easy to fill and the parts come off and go on very easily.


    • Familiarity: I've used it several times

    The hose attachment at the top of the bladder makes it easier to load, especially in a external pack sleeve. The hose is slightly larger than average, which is supposed to make the flow rate faster. Very easy to fill.
