Sometimes the gear that earns classic status does so simply by doing its job well, year after year.

The Platypus Hoser is the reservoir that built the brand's reputation in the backcountry, and it remains a strong choice for paddlers, hikers, and backpackers who want reliable hands-free hydration without unnecessary complexity. The updated HyFLO bite valve delivers a 30% increase in flow rate over the previous design, so getting water on the move is faster and less effort. Embedded silver-ion technology keeps mould and bacteria from taking hold between uses, and all materials are certified taste-free, BPA-free, BPS-free, and phthalate-free.

The integrated hang and carry loop makes it easy to secure the reservoir inside a pack or hang it at camp, and the threaded port accepts any compatible Platypus accessory cap or drink tube kit, including the Platypus Drink Tube Kit for converting it to a custom configuration. A straightforward, ultralight hydration reservoir that has earned its place in Canadian backcountry kits for good reason.
