Snowboard bindings - Men -
The Force Classic from Union is a snowboard binding designed to offer a precise balance between support, comfort, and responsiveness.
With its forgiving flex, it provides enough stiffness to effectively transfer pressure while maintaining enough suppleness to follow movements and remain versatile across all terrains. Its S4 Duraflex ST baseplate ensures a robust and responsive structure. The multi-density thermoformed EVA foam cushioning absorbs vibrations and enhances comfort underfoot, while the 3D extruded aluminium heelcup optimises heel retention while minimising drag. The S1 Duraflex ST highback completes this setup for precise movement transmission.
Support is provided by an Exoframe 4.0 ankle strap and a TS 2.1 UltraGrip toe strap, offering precise and even tightening. The EXO Quick-Lock adjustments allow easy strap customisation to fit your morphology. The Cam-Lock forward lean and 3° canting promote a natural stance and help better align legs and knees.
With grade 8.8 steel hardware and an aluminium S2 ratchet with steel base, the Force Classic focuses on durability and reliability to accompany you on all your runs.
