Evolve into a backcountry shredder with the SideSeth.

It usually starts when you find yourself eyeing the sidecountry gates or staring out over Chamonix's vast mountains (like pro-skier Seth Morrison). Then it progresses to bootpacks up increasingly steep couloirs. Be sure to have the K2 SideSeth beneath your feet or strapped to your pack. Designed to ski more technical big-mountain terrain, this hard-charging plank has a stiffer tail with slightly less rocker for improved hard snow performance. Its slightly raised kick tail also retains versatility and forgiveness in narrow, concave couloirs so you can get nasty without holding back.


  • Powder rockered profile (50% rocker and 50% camber) has an elevated tip and the longest measurement of rocker which enables you to float on top of pow and bust through crud and chopped-up snow
  • Powder rockered profile also gives enough camber to ensure solid edge hold in firmer conditions
  • Powdered Tip (design pulls the widest point of the tip further down the ski) creates lift, initiates float, and minimizes deflection in adverse snow conditions
  • Fir, aspen, and maple wood core provides a solid, durable, and powerful ski
  • Hybritech construction combines the accuracy and powerful performance of a sidewall-constructed ski with the light weight and smooth turn initiation of cap-constructed ski
  • Carbon Web technology (webbed carbon overlay located on the tail and forebody of the ski) gives lightweight torsional rigidity, which increases edge grip especially when you skin up an icy sidehill
  • Tip and Tail hardware functions as attachment points for your K2 SideSeth Precut Skins (sold separately) and comes with a removable plug
  • Tip and Tail holes also allow you to build a rescue sled, construct various ski anchors, and carry less weight while increasing your safety margin
  • Item #K2S1112
