Union STR men's snowboard bindings blue 2210645 (2210645)

Modern, reliable, and designed with adaptability in mind — Union STR bindings are the choice of men who expect maximum performance from their gear. With their advanced construction combining durability and precision, they are the perfect companion for both expressive descents and technical freestyle maneuvers.  

The Union STR bindings are equipped with a rigid composite Stage 5 Duraflex base, which provides not only durability but also flexibility and response necessary for versatile riding. This lightweight and impact-resistant base with additional subtle canting is ideal for riders of various skill levels, offering everyday comfort and good responsiveness.

The bindings feature lightweight and durable aluminum buckles that facilitate adjustment and ensure long-lasting use. The new mechanism combined with aluminum buckles increases the bindings' durability and reliability. Solid and sturdy aluminum heelcups provide low weight and proper transfer of leg movements to the board. These are the strongest aluminum heelcups available on the market, which speaks to their exceptional quality.

The strongest steel on the market, 8.8 grade screws, ensure the bindings' solidity and longevity. They are extremely important for safety and durability even during intensive use. Support for the anatomical positioning of the knees thanks to the base canting, which increases comfort and may help prevent injuries. Canting allows for a natural foot position, which is key for comfortable riding.

EVA
Ethylene Vinyl Acetate, which is a foam-like material used in, among other things, sports shoes and many items of clothing and sports equipment. It provides an optimum balance between flexibility and durability.
Extruded 3D Aluminum
Extruded 3D Aluminum is a specially designed aluminium heel construction that provides optimal heel hold and minimises drag.
Tool-less
A system in the snowboard binding that ensures that no tools are needed to adjust it.
Grade 8.8 Steel
The strongest steel available on the market, used in snowboard bindings by Union, among others.
TS 1.0 Hexgrip
The TS 1.0 Hexgrip technology is a plastic toe strap that adapts perfectly to the shape of the shoe, guaranteeing a secure fastening. It can be fastened classically from the top or at the tip of the shoe.
S5 Duraflex
The material used for the base plate in Union bindings. Manufactured using S5 Duraflex, the plate has a medium elasticity, providing comfort and good responsiveness for all-day riding.
S11 Duraflex
The material used to manufacture the skeg in Union bindings. It maintains a good balance between elasticity and stiffness, ensuring comfort when riding. Will work well for beginners and intermediates.
Exoframe 2.0
The ankle strap design of the Union bindings. It is lightweight and durable, strikes a balance between flexibility and stiffness and gives a 'closed ride' feel, increasing the sense of security.
