When we're headed out multi-day ski traverses in the high alpine, the Peak 40L Dry Backpack is our top choice for storing our equipment. The lightweight design is completely waterproof thanks to welded seams which keep everything in the generous amount of storage dry no matter the weather. The hip belt and stabilizing strap ensure comfortable carrying over long miles, and standard ski touring features like a separate avalanche safety pocket and integrated ski-carry keep your equipment accounted for.
