For long tours and technical ski mountaineering objectives where the ascent is as involved as the ski down, the Alias AvaLung combines the technical features of BD's climbing packs with winter-specific functionality.

BD's reActiv suspension moves with you, whether you're hop-turning down a couloir or booting a knife-edge ridge, and the tuck-away rope strap and ice-tool PickPockets secure your gear during the approach and the descent.
