BreakdownThe Platypus Big Zip EVO personal hydration system is perfect on an extended backpack hunt. It features a low-profile reservoir with an easy-to-clean wide-mouth opening and a low-profile design that fits the back panel of any pack. The embedded silver-ion protects the reservoir from mold and bacteria. A quick-release hose and shutoff valve make drinking and refilling a breeze. This new EVO version has been modified to produce a 50% faster flow rate. (3L size pictured)
