Since Osprey® was founded in 1974, 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 that makes Osprey a company like no other.

To celebrate its 35th anniversary in 2009, Osprey launched the All Mighty Guarantee, an enhancement of a lifetime warranty that was already one of the most robust in the industry. Free of charge, the company will repair any damage or defect in its product — whether it was purchased in 1974 or yesterday. If Osprey is unable to repair the item, it will happily replace it. The All Mighty Guarantee: any product, any reason, any era.

No wonder there's such a close relationship between the words Osprey and Quality. You could say it's a lifetime commitment.
