The Coomback remains in the line as an enduring tribute to fallen K2 friend Doug Coombs. A portion of proceeds from the sale of his signature model goes to Coombs's family, another portion to the American Mountain Guide Association. With its moderate width and rocker, it's designed for versatility: "equally adept making tram laps (at Jackson Hole) or climbing the Ford-Stettner route on the Grand Teton." It's a metal-free, wood-core (fir/aspenmaple) cap construction with strategically placed carbon-fiber reinforcement, weighing in at 1,720 grams at 167 cm. K2's All-Terrain Rocker combines 70 percent camber with 30 percent tip/shovel rocker to smooth the ride, enhance forgiveness and improve soft-snow flotation. The Powder Tip is tapered so it's less easily deflected and swing weight is reduced. All Backside Adventure skis share a number of tour-specific features: Precut skins are sold separately, and the tip and tail have skin-ready attachment holes. The Snowphobic topsheet sheds weight-adding snow (especially when waxed) on the ascent. The flat tail is snow-anchor appropriate.
