The K2 HardSide Climbing Skins are perfectly pre-cut to fit the K2 HardSide Skis. Equipped with K2’s own Z-Clip attachment system, arguably the cleanest and most streamlined in the business, the K2 HardSide Climbing Skins are super secure, and the glue offers just the right combination of adhesion and releasability. Adjustable tail straps that attach on the top side of the ski take up slack and eliminate drag at the tails.
