The Black Diamond Anarchist Winter Pack comfortably carries all your gear for a day of backcountry skiing, and it can save your life with its integrated Avalung. Couloir Magazine was so impressed they gave it the Design Innovation award. The shoulder-mounted mouth piece is easy to access if you get caught in a slide, and it increases your chances of survival by helping you breathe under the snow. If youre the one searching, pull off this pack, open the front avie pocket, and quickly remove your shovel and probe. The Anarchist Pack with Avalung is available in a 32L size for half-day tours and a 42L size when youre in the backcountry from sun up to sun down.
