Product Description
Built for women who live in the park and demand every edge of performance, the Union Ultra Women's is a freestyle binding rebuilt from the ground up. The Molecular Bushing suspension system floats between baseplate and board to kill vibration and preserve natural flex, while the asymmetric Duraflex ST baseplate and highback sharpen response right where you need it. A magnesium ratchet system and PU Layered EVA ankle strap lock everything in place without weighing you down.

Ultra Women Snowboard Bindings - Black 2027 FAQ
How does the Molecular Bushing improve comfort?
The Molecular Bushing acts as a suspension system between baseplate and board, absorbing impact and vibration. Combined with TPE outsole, it delivers smooth underfoot cushioning while maintaining responsive board feel.
What does the 2-Stage forward lean adjustment do?
Integrated 2-Stage forward lean gives you two discrete angle options for stance tuning, tool-free. Dial in your preferred forward lean to match your riding style and terrain preference.
Is 8/10 all-mountain score good for mixed terrain?
Yes. Combined with 9/10 freestyle, the Ultra Women's is a high-performance hybrid excelling in both park and all-mountain. The 6/10 flex and S11 mini disk balance responsiveness with stability across conditions.
Will the Magnesium ratchets last through a full season?
Yes. Magnesium S1 ratchets with steel base are four times stronger than aluminum at half the weight. They're engineered for durability and long-term reliable operation through heavy use.
