What Our Gearhead(R) 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(R) approved NanoFly(R) and recycled high-tenacity nylon, the Mutant 22 is proof that lightweight gear can still pack a punch.
