Main Information

Union Strata

Union’s #1 men’s park and freestyle binding, the 2026 Strata is built for riders who want to press, pop, and play across the entire mountain. With a soft, surfy flex and industry-leading shock absorption, it delivers a buttery ride that doesn’t compromise on control. Whether you're hitting rails, boosting side hits, or slashing pow, the Strata lets your board flex naturally—just the way it was meant to. A true Union favorite.

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.

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.
