An ultra-lightweight and strippable climbing pack, for use all year round.

The Osprey Mutant 38 is a superb Climbing Pack, designed for year-round ascents but also ideal for ski touring and alpine hiking.

Active winter climbers will welcome the snow-shedding backpanel, side ski carry loops and dual ToolLock™ system which allows quick and secure ice axe attachment.

When summer arrives you will benefit from the EVA die-cut ventilated shoulder harness and the ability to strip 380g from the total pack weight by removing any features you won’t need.

A floating and removable top lid allows you to cram in all your gear and easily secure your climbing rope, yet you can quickly remove the lid altogether when not needed.

The built-in FlapJacket™ provides a weatherproof closure and keeps your gear fully compressed, also concealing an integrated mesh helmet storage pouch which loops over the lid and clips on securely.
