Mountain Hardwear’s ultra-lightweight Snowskiwoski 40L pack is built to withstand the rigors of the high alpine. This mountaineering must-have is chock-full of tech you’ll come to appreciate in the backcountry—like a dual-density shoulder strap with multiple lash points for connecting your radio, an on-the-fly removable ski carry strap, and interior hydration sleeves that double as rope stow.
