Product information

Osprey’s Mutant 38 is one of the popular climbing-specific packs in the series. A little more space than the smaller version, it allows for expended expeditions while still being lightweight for fast-moving on the mountain. Features include the snow-shedding fabric back panel, side ski carry loops and dual ToolLock system which allows quick and secure ice axe attachment.

Rock Climbing in the summer or ice climbing and ski touring in the winter, Mutant 38 will be your perfect partner in climb. The main access point is through a floating and removable top lid, which means you can overload your pack or remove the lid for greater head clearance and less weight. The built-in FlapJacket provides a weatherproof closure to keep gear fully compressed. Also included in the top pocket is a rapid deploy mesh helmet storage pouch. The hipbelt is reverse-wrap with integrated gear loops to deliver choice of comfort, minimalism or gear racking options.

Santa Cruz California 1974. Mike Pfotenhauer sat at his sewing machine with a head full of ideas and a burning passion to build the most innovative backpacks to the highest standard.
