http://www.rei.com/snowsports The K2 DarkSide skis were meant for one purpose: blazing through bottomless powder during adventures in the backcountry. Epically proportioned 128mm waists create excellent flotation and easy handling when laying first tracks though untouched bowls. Extremely lightweight aspen and paulownia wood core produces a natural flex, allowing the ski to achieve full contact with the snow throughout the turn.
