Osprey’s Hydraulics® Bite Valve provides a high-quality replacement for your old, neglected and beat up bite valve. The bombproof ¼ twist shut-off design guarantees you won’t experience any unpleasant wet surprises.

Since Osprey was founded in 1974, every single product design has passed through the hands of owner and founder Mike Pfotenhauer, who created his first backpack at age 16.

In Santa Cruz, California, the young entrepreneur opened a retail shop in the front of his rental house where backpackers and travelers came for custom-fit, made-to-order packs constructed over several days by Mike himself. As the demand for the great-fitting packs increased, Osprey found itself relocating to its current home in Southwest Colorado.

Today, Osprey is a melting pot of diverse personalities, backgrounds and abilities. All share the common belief that adventure is open to everyone and found anywhere.
