Main Information

Union Source FC

The connection between the rider and the snowboard has never been closer. We've removed the mounting disk, reduced the baseplate height, shaved off hundreds of grams of excess material and completely changed the way that the rider's energy is transferred from the body to the snowboard. The Union Source FC puts you in the driver's seat, are you ready for the ride?

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.
