Platypus Hoser Bladder

The Platypus® Hoser™ Bladder is the ultralight, minimalist version of the original Platypus reservoir we all came to love. It still has the same taste-free, durable design that makes this great for backpacking, fast packing, sky running, and day hikes. New and improved features include a self-sealing ™ bite valve that delivers 30% more flow! Making you drink more water with less effort so you can hydrate on the go.
