A ski for use on ice or snow is disclosed. The ski includes a ski body having a tip portion, a tail portion, and a longitudinal running length extending between the tip portion and the tail portion and a substantially flat bottom surface for sliding on snow or ice. The ski also includes a suspension system comprised of a substantially rigid support structure secured to the longitudinally central region of the said ski body at two attachment locations separated by a distance of at least 5 inches along the longitudinal axis of the ski body, and at least one resilient element configured to exert an opposing force between the support structure and the ski body in the area between the two attachment locations.

A snowboard having a unibody base layer constructed from a seamless and single continuous piece of material and methods for fabricating the snowboard with a unibody base layer having a central recess for nestling layers of the snowboard therein, a tip, tail and sidewalls as well as exterior grooves for attaching edges on the exterior of the unibody base layer. The resulting snowboard having increased resistance to water penetration, increased structural integrity and overall material strength, resistance to rotting of materials, decreased overall weight and improved flexibility.

The present invention relates to an alpine ski including a tip zone located at the front of the ski, a waist zone, and a tail zone located at the rear of the ski, a median longitudinal plane extending from the front end to the rear end of the ski, an underside formed by a gliding sole bordered by edges, a zone for mounting a boot. The alpine ski further defined by a radius of curvature measured along the sidecut of the alpine ski.
