Every component of the Ultra acts as a suspension system for your riding, loading, and unloading with every movement as you snowboard.

Key Features:

S15 Ultra Duraflex ST Highback
A thin layer of molecular bushing provides increased flexibility and a spring-loaded return for quick edge-to-edge power when you need it.

Astro Ankle Washer
Union's Astro ankle washer adds another level of confidence and security to your riding. Prevents heelcup slippage on binding models that only feature a single heelcup screw.

Magnesium S1 Ratchets
Magnesium S1 ratchets are Union’s answer to the elements. A fully integrated spring protected from the harsh outside provides you with Union’s best ratchet to date. Longer life span and better spring return guaranteed.

Forma X Ankle Straps
Instant response meets all-day-long foot comfort. The Forma X ankle strap's all-new construction combines our responsive Exoframe exterior with the padded comfort and flexibility of the Forma interior.

Stage 11 ASYM Duraflex ST Baseplate
By removing excess material in the toe and heel of the baseplate, and utilizing a brand-new asymmetrical shape, we've been able to drastically increase the torsional flex of the binding.

Molecular Bushing
Union's all-new Molecular bushing provides spring-loaded take-offs and perfectly cushioned landings. 15% lighter than Union Fused Vaporite and guaranteed to minimize foot, ankle, and knee fatigue. This is the future of freestyle binding design.

TPE Outsole
Exclusive to Union, this 100% new binding manufacturing process requires zero bushing gluing and adds another layer of dampening and vibration canceling to the all-new Ultra.
