Men's snowboard bindings Union STR black (11010500)

The Union STR black men's snowboard bindings guarantee precise energy transfer and high control while riding in varied terrain. Appropriately selected technologies, such as EVA foam cushioning and quick adjustment systems, allow for a smooth fit tailored to personal needs and riding style.

Advanced technologies and adjustment systems

The Union STR model is equipped with an S5 Duraflex base and an S11 Duraflex highback, significantly improving the stiffness of the construction and the effectiveness of the bindings on the slope. A high level of comfort is ensured by the EXT thermoformed EVA foam cushioning system, which effectively absorbs vibrations and reduces the impact on the feet. Riders can expect quick tilt adjustment thanks to the Tool-less adjustment system and full control over the board with the Camber Disk.

Durable materials and precise fit

The bindings utilise a heel made from extruded 3D aluminium along with two aluminium buckles and aluminium pumps, which enhances their durability and reliability during intense use. The Exoframe 3.0 Ankle Strap and TS 2.1 Tiles ensure an even distribution of forces and secure foot hold regardless of riding conditions. A flex rating of 6/10 allows for versatile use – both during dynamic descents and relaxed riding in the snowpark.

All-mountain construction and user comfort

The Union STR black bindings are designed for versatile all-mountain use, allowing for performance both on groomed trails and off-piste. Implemented technical solutions support user comfort even during long days on the slopes. The entire construction has been optimised for lightness, durability, and quick adaptability to various snowboard boots.
