Osprey Packs

Mutant 22 Backpack

What Our Gearhead® Experts Are Saying:

"I’ve taken the Mutant 22 on everything from fast alpine pushes to local mixed lines, and it’s hands-down one of the best minimalist climbing packs out there. It carries close, keeps gear secure, and sheds snow like a champ. Love that it’s glove-friendly and tough enough for sharp ice tools and rock contact."

When vertical terrain calls, we reach for the Osprey Mutant 22 Backpack—built for fast, focused alpine missions and tested by guides who know the mountains inside and out. This compact pack delivers the essentials in a streamlined package, with the latest iteration bringing lighter, tougher fabrics and refined features that make every move on snow, ice, or rock more efficient.

The alpine-specific design includes glove-friendly buckles, dual ToolLocks for secure ice tool carry, and an internal compression system that secures a rope without bulking out the profile. It’s engineered to carry close to the body for stability on sketchy ridgelines and mixed terrain, while a snowshed backpanel prevents buildup and keeps the pack performing cleanly. Made with bluesign® approved NanoFly® and recycled high-tenacity nylon, the Mutant 22 is proof that lightweight gear can still pack a punch.
