The Skin pack builds on the concept of trail vests, which have grown in popularity amongst mountain runners for their ability to carry equipment in a streamlined, accessible, and balanced way. The Xpress ski carrying system allows skis to be attached and removed without removing the pack. A special side-entry pocket near the right hip allows single-handed, fast access to crampons without taking off the pack and can be zipped open from the inside to connect to the main compartment. This pocket is also great for water bottles, snacks, clothing, cameras ? anything you might want access to while on the move. The Skin also features the exclusive EZ OP buckles on the chest strap and waist belt which use a one-handed pull tab for faster, easier opening. The interior has a fixed sleeve pocket specifically designed for shovel and probe, a small zippered security pocket, and hydration bladder attachment points. The exterior includes ice axe carriers and a helmet carrying system.
