Since Osprey’s founding, every single product design bearing the Osprey name has passed through the hands of owner and founder Mike Pfotenhauer, undergoing relentless scrutiny. From stitching the first lines of custom-fitted packs, to meticulously designing innovative products with intuitive features, to forging personal relationships with the sewing operators who construct the packs, Mike has been the unbreakable thread of the company.
The new Osprey Hydraulics reservoirs up the performance ante with new features to improve handling, reduce weight and simplify operation. The wide-mouth top opening simplifies filling and cleaning. It folds closed and is secured with a patented slider that creates a strong, leak-proof seal. Osprey's unique PourShield feature makes filling and pouring a snap, while the welded TPU handle makes it a one-handed operation. To top it all off, the new design reduces weight by 20% to 30%.
