We're breaking out the fatties. The Sidestash is the widest ski in K2's Backside series and it's your ticket to untracked powder. The 108 mm waist and shoveled tip allow for greater floatability than other skis in the series. An Aspen/Paulowina core make for a damp ski and smooth ride while a metal laminate and sandwich construction keep the boards strong under pressure. Use the tip and tail holes to attach pre-cut K2 skins and hike outside resort boundaries. Like us on Facebook and get entered to win these special Rolling Stones skis from K2.
