Binding Performance
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.

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

Binding Flex
Union Bindings come in a verity 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.
