Osprey Mutant 38 Climbing Rucksack

Now in its fifth version, Osprey's Mutant 38 remains a well-featured, versatile option for year-round cragging or fast Alpine and Scottish winter ascents. 

Super light, flexible, strippable and practical, the floating and removable top lid lets you overload like a packhorse or remove the lid totally when you're travelling light. You can use the built-in FlapJacket ™ for weatherproof closure and to keep your gear fully compressed, while in the top pocket you'll find a mesh helmet storage pouch.

When making cold-weather ascents, you’ll appreciate the snow-shedding fabric backpanel, side ski carry loops and dual ToolLock™ system, which allows quick and secure ice axe attachment.

The reverse-wrap hipbelt features integrated gear loops so you can choose between comfort, minimalism or gear racking options. For rock climbing in the summer or ice climbing and ski touring in the winter, the Mutant 38 is your perfect partner in climb.
