Osprey’s Hydraulics reservoir system features thermoplastic polyurethane (TPU) construction, and is entirely BPA-, phthalate-, and lead-free. The wide-mouth opening makes filling and cleaning easy, while their patented QuickConnect hose assures a reliable and convenient connection. Blaster bite valves are designed to provide high-volume flow, and the magnetic harness clip ensures secure and accessible valve placement.


The AirScape system by Osprey utilizes 3D foam back panels to keep the pack close to your body, forming a stable, secure fit. The panels are highly ventilated to prevent excess perspiration, and the foam adheres to your shape for long-term comfort. With six inches of adjustability, the AirScape system is designed to optimize the fit for a range of body types and sizes.
