evo.com | K2 Snowboard Bindings > The K2 Program Snowboard Bindings deliver powerful freeride performance while pioneering sustainable construction that doesn't compromise capability. Built around K2's innovative Module Chassis with components derived from castor beans and sugarcane, these eco-conscious bindings feature a stiff, responsive flex pattern that excels in deep powder and steep terrain. Proof that shredding and sustainability go hand in hand. FR1 Highback The new FR1 Highback harnesses the strength and sustainability of the castor bean, and represents a huge step toward K2's goal of carbon net-neutrality. Module(TM) Chassis Featured on all K2's new bindings, the Module chassis is composed of a fiberglass infused nylon, and minimizes "dead" board flex zones directly underneath the binding. This in turn allows the rider to feel the flex and response of the entire board length, while providing maximum support, security, comfort, and vibration damping. Flex Rating 9 (1 Soft - 10 Stiff) Forward Lean Block Dual Density Ankle Strap K2's new dual density ankle strap harnesses the strength and sustainability of the castor bean, and represents a huge step toward the goal of carbon net-neutrality. | K2 Program Snowboard Bindings 2026 - Large in Green | Nylon
