Every model in K2' s massive ski collection features one of five variations of the rocker concept: All Terrain (moderate tip rocker plus camber), Speed (very mild tip rocker plus camber), Catch Free (mild tip-and-tail rocker plus camber), Jib (mild tip-and-tail rocker plus a flat midsection), and Powder (rockered forebody plus cambered rear). The ObSETHed is part of K2' s Factory Team series, which consists of skis used by K2' s pro team athletes. Narrower and stiffer underfoot than the Hellbent, Seth Morrison' s pro model is built for charging fast, steep lines and sending big drops, but it retains plenty of width, at 117mm in the waist, to float deep snow. Powder rocker helps it plane high in deep snow and ups maneuverability. Holes in the tip and tail accommodate pre-cut climbing skins (sold separately). This version is sold with a 12-DIN binding featuring adjustable mount position.
