Discover the Union STR bindings

The Union STR bindings combine durability and versatility, making them an excellent choice for snowboarders of all levels, with a perfect balance of stiffness and flexibility.

Design and materials


The Stage 5 Duraflex baseplate provides a footbed that combines comfort and response for long sessions. The construction withstands intensive use and is tuned for all-mountain adventures. The S11 Duraflex highback adds the perfect mix of flex and support, with a forward lean for improved carve performance.

Performance and technology


The binding has a flex rating of 6/10, combining mid-flex characteristics with enough stiffness for controlled rides. The EXT Thermoformed EVA bushing dampens vibrations and supports even board flex. The Extruded 3D aluminium heelcup keeps the heel firmly positioned and minimizes rotational loss for efficient power transfer.

Comfort and fit


The Exoframe 3.0 ankle strap combines a lightweight exoframe with soft padding for instant response and long-lasting comfort. The TS 4.0+ toe strap wraps the forefoot without pressure points and is quickly adjustable without tools. The tool-less strap adjustment allows easy tuning on the mountain.
