Product information

A pack designed for year-round mountain use when carrying large loads or taking part in climbing expeditions. Super light, flexible, strippable and seasonally versatile you can rely on this perennial climbing partner.

When making winter 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 main entry to the Mutant 52 is through a floating and removable top lid, which means you can overload your pack like a packhorse or remove the lid totally for greater head clearance and lighter weight.

Lesser climbing packs have minimal weather protection and compression when in this mode, but not the Mutant 52. Use the built-in FlapJacket ™ that provides weatherproof closure; it keeps your gear fully compressed. Also included in the top pocket you will find a rapid deploy mesh helmet storage pouch. The removable and reverse-wrap hipbelt with integrated gear loops delivers your choice of comfort, minimalism or gear racking options. To strip weight for fast and light mountain assaults, you can remove the framesheet, top-lid and hipbelt to save 725g. Mutant 52 will be your partner in climb, however tough the mountain.
