Hoser Reservoir

Slide the Platypus Hoser Hydration Bladder into your pack, and enjoy having hydration access throughout your hike, ride, or whatever activity you enjoy. Platypus made this reservoir with 100% BPA-free material, and added embedded silver-ion to the inside so you won't end up with unidentified black bacteria camping out in your water bladder. The HyFLO bite valve hooks you up to fast-flowing water, while the modular design fits into most backpack hydration sleeves.
