For cold-weather missions, we’ve created a pack just for winter conditions: the Carson Mountain Ruck. The bag is a classic top-loader with a fast-access, tri-zip front pouch for avalanche tools storage. At 6000 cu inches, the bag has enough features to organize the largest loads and six rows of MOLLE webbing on each side for your own additions. Side zippers get you into the main bag without having to dig down through the top and the bottom part of the pack is our SpeedZip sleeping bag compartment. The tri-zip front neatly stores a snow shovel, handle and probe. The lid is a 900 cu in Daypack lid that is removable and has built-in, lightweight shoulder straps, allowing it to be carried on its own.
