Mutant 52L Backpack

For big objectives and epic missions, the Mutant 52L Backpack is the pack to take along with you when you're planning on moving light and fast. Osprey slimmed down this pack so it only has the necessary bells and whistles to accommodate the tools you need to get the job done while playing in the high mountains. The large volume provides enough space so you're able to hike all your gear in to set up basecamp, and still sneak in a couple extra luxuries of home. Gear loops on the removable waist belt add access to extra gear when you're on the move, and a three-point haul attachment evenly distributes the weight of the pack so it can be stored at an anchor and hauled up a pitch when the climbing gets technical. Additional helmet and ice tool carry means that you can store your gear safely and securely on the way back to the car.
