The Mutant 52 has everything you need for the approach to basecamp and the route ahead.
Your most committing alpine rock and ice pursuits demand a pack that's up for the challenge. The Mutant 52, with its dialed-in features and expansive capacity, is here to answer the call. Tested and developed by local guides and athletes in some of the harshest conditions, the Mutant 52 has evolved into a formidable mountaineering pack for big objectives.
