Black Diamond Mission 50 Backpack. Built to tackle everything from mixed pitches on Camp Bird Road to big ice routes in the Ghost, the Mission 50 is Black Diamond's super durable pack outfitted for the demands of winter cragging and alpine climbing. The Mission's reACTIV XP suspension allows the pack to move with you while stabilizing big loads on the approach. The pack's 50 liter capacity swallows your ropes, rack, layers and other essentials while the ice tool PickPocketsTM and exterior crampon pouch secure your sharp things. The Mission 50's padded hipbelt is also removable for streamlining on alpine routes.
