Product Description
The Ultra is Union's most comfort-forward freestyle binding, engineered around a Molecular Bushing suspension layer that absorbs chatter and returns energy with every turn. An asymmetric Duraflex ST baseplate keeps the footprint tight under your board, while magnesium ratchets cut weight without compromising grip. The PU-core hybrid ankle strap and tool-free 2-stage forward lean adjustment complete a setup built to flow as naturally as your riding.
Product Details

Ultra Snowboard Bindings - Orange 2027 FAQ
The Ultra Men's says it's NEW/UPDATED—what changed?
The Ultra Men's was updated with the all-new Molecular Bushing and TPE Outsole for enhanced suspension and board feel, paired with the S11 asymmetric mini disk design and Integrated 2-Stage forward lean for precise tuning.
What's the difference between a mini disk and regular 4x4?
The S11 mini disk has an asymmetric footprint optimized for freestyle riding. It allows true board flex with a smaller contact area, ideal for park and responsive all-mountain play.
Is the 6/10 flex soft enough for park tricks?
Perfect. 6/10 is a medium-soft flex paired with 9/10 freestyle rating. It rewards tricks and creative riding while remaining capable in all-mountain terrain—true hybrid binding performance.
Will the PU Core ankle strap hold my boot securely?
Yes. The Hybrid 1.0 strap with PU Layered EVA core is waterproof and super-durable, molding to any boot shape. Quick-Lock adjustment ensures a secure, locked-in feel without pinching.
