Osprey Mutant 22 backpack Blue flame

The Osprey Mutant 22 is a technical mountaineering backpack with a 22-litre capacity and a Dual ToolLocks system, designed for ice climbing and single-day mountain ascents. Its narrow profile and close fit provide stability and allow secure movement on steep, technically demanding terrain.

Who is the Osprey Mutant 22 designed for?

It sits at the top end of the technical climbing backpack range for vertical ascents. It is designed for mountaineers, ice climbers and alpinists looking for minimalist yet exceptionally durable equipment for day trips. Its construction, without unnecessary external features, reduces the chance of snagging in narrow chimneys or against rock.

Key features and technologies

• NanoFly™ material: The main body and base are made from recycled 210D nylon with NanoFly™ mesh, providing exceptional abrasion resistance while keeping weight low.
• Dual ToolLocks system: Enables two ice axes to be attached quickly, securely and easily using elastic loops, which is essential when transitioning from climbing to walking.
• Snowshed back panel: Special fabric on the back panel prevents snow from accumulating and sticking, keeping your back dry during winter ascents.
• bluesign® certification: Confirms that the materials are made sustainably and with care for the environment, without harmful PFAS chemicals (PFAS-free DWR).
• Three-point haul system: Three reinforced attachment points allow the backpack to be hauled safely and securely up a wall during multi-pitch climbs.

In use

For ice climbing and winter mountaineering, the Dual ToolLocks system and snow-shedding back panel ensure easy handling of your equipment and comfort even in the toughest conditions.

On multi-pitch rock routes, the backpack’s narrow profile and weight of just 0,65 kg allow unrestricted arm and shoulder movement, while the three-point system makes it easy to haul the backpack over the most challenging sections of a route.

For fast day trips, the internal hydration bladder pocket and rope attachment loops help distribute weight optimally and provide quick access to fluids.
