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). Like all models in K2' s Backside Adventure series, the She' sBack features holes in the tip and tail to accommodate pre-cut climbing skins (sold separately). The She' sBack is the narrowest women' s model in the series, designed for light-and-fast gals whose descents are as gnarly as their tours are long. The topsheet consists of a snow-shedding material that prevents buildup during ascents.
