Main Information

Union Atlas Step On®

Schnell rein. Schnell raus. Sicher fixiert für volle Kontrolle. Der Union Atlas Step On® kombiniert den bewährten Komfort der Step On® Technologie mit Unions renommierter All-Mountain-Performance. Mit dem Step On® Instant Connection™ System bietet diese Bindung blitzschnellen Ein- und Ausstieg, ohne dabei Response, Präzision oder Power einzubüßen.

Union Binding Company ist der einzige Lizenzpartner, der seine eigenen Produkte entwickelt und produziert, die mit dem Step On® Instant Connection™ System ausgestattet sind.

Riding Category
Freestyle Rating: Freestyle bindings are designed for riders looking for the ultimate freedom, comfort and that “loose truck” feel. These bindings are generally best suited for riding park or riders looking for a more soft and surfy board feel.

All Mountain Rating: All Mountain bindings are generally mid-flexing and built to handle all terrain and all riding styles.

Performance Rating: Performance bindings are stiffer, provide instant edge-to-edge response, and the most stable board connection possible. Performance bindings are generally best suited for high speed carving or ridding steep technical terrain.

Freeride Rating: Freeride bindings are built for off-piste exploration, deep powder, and challenging backcountry conditions. They combine support, comfort, and responsiveness, allowing riders to tackle variable snow and steep terrain with confidence.

Binding Flex
Union Bindings come in a variety of flex ratings. The baseplate, highback, straps, bushing and disk all have different stiffnesses to help give a specific ride feel and function. Softer flexing bindings are generally used for more surfy or freestyle riding, while stiffer bindings are generally used for more hard charging and responsive freeriding.
