A board including a plurality of elongate members and first and second non-permeable first fiber reinforced material layers. Each of the plurality of elongate members are cooperatively positioned to form a perimeter of a polygon. The non-permeable first fiber reinforced material layer is secured to a top surface of the perimeter of the polygon. The non-permeable second fiber reinforced material layer is secured to a bottom surface opposing the top surface of the perimeter of the polygon. A void is defined within the perimeter of the polygon between the first fiber reinforced material layer and the second fiber reinforced material layer.

A splitboard fastening system comprises a crossbar comprising a shear bushing interface and a hook, an eccentric post coupled to a lever and configured to engage an inside edge of the hook in response to rotation of the lever, and a shear bushing configured to engage the shear bushing interface, wherein the crossbar is configured to be coupled to a first splitboard ski, and wherein the eccentric post and the shear bushing are configured to be independently coupled to a second splitboard ski.

A foam product includes a foam core, a soft skin covering the foam core, and a base structure on which the foam core is disposed. The foam core of expanded beads has an outer surface on which some outermost beads of the expanded beads are exposed and bulging outward with different heights to form a bubbly texture. The foam skin has an inner surface attached to the outer surface of the foam core, and has at its inner surface a plurality of concave cavities each matedly surrounding a respective one of the bulging, outermost beads on the outer surface of the foam core.

A system, method and apparatus for a digitally Controlled Variable Stiffness item of athletic equipment, such as a Ski, Snowboard, and Boots. A core of thermally responsive metal alloy, such as Nitinol is disposed within the athletic equipment. A thermal control module and controller permit the athlete to program the athletic equipment to a desired stiffness parameter. The controller may include an app operable via a mobile computing device in communication with the thermal control module.

The invention concerns a device for controlling a monoski (1), in particular for snow, by means of the combined simple rotation and simple tilting of a single control member such as a handlebar, simultaneously by lateral inclination and by longitudinal twisting. It therefore combines the necessary mechanical functions of a pair of conventional fixtures with the ease of use of a bicycle, and does not require a specific monoski. It makes it possible to move freely on the snow, controlling with both feet held but not locked, or indeed to use one foot to help push on flat terrain and provide stability. The lever arm provided by the control member is considerably superior to that of a pair of conventional fixtures, greatly improving ease of use and the maximum capacities of the device. Finally, it can be quickly folded for ease of handling and storage.
