Union Ultra Womens 2025

The 2025 Union Womens Ultra is designed to give you the highest level of response and suspension in a freestyle binding. Packed with features that when combined keep the weight low, while each component acting as suspension for your riding, loading and unloading with every movement you make.

Binding Type: All Mountain

Flex: 5/10 (Mid)

Board Compatibility: This Union binding comes with a Minidisk, compatible with 2x4 and channel binding mounting systems.

Baseplate:

Stage 11 ASYM Duraflex ST

With an asymmetrical shape, and removing the excess material in the toe and heel of the baseplate, the Stage 11 has improved torsional flex of the binding.

Highback: 

S15 Ultra Duraflex ST

The S15 Ultra Duraflex highback has 6 degrees of forward lean to increase edge to edge response, and with the new bushing it gives you improved flex and rebound while riding.

Buckles: 

Magnesium S1

A construction process completely unique to Union allows them to make their ratchets out of Magnesium, resulting in a product that is 4 times stronger than aluminium while being half the weight. Not only that, it's easily recycled so the environment benefits too.

Straps: 

Forma X Ankle Strap + TS 5.0 Ultragrip Toe straps

The Forma X ankle straps get the balance right between response and comfort. The Exoframe exterior gives you all the support you need, with the flexibility of the Forma interior. While the multi-positional and anti-slip material of the TS 5.0 Ultragrip Toe strap keeps you locked in and on point

Cushioning:

Molecular Bushings

The Molecular bushing gives you spring loaded take offs, with cushioned landings. 15% lighter than the Union Fused Vaporlite, it is guaranteed to minimize foot, ankle and knee fatigue.

Additional Features:

Extruded 3D Aluminium Heelcups with Astro washer:

This heelcup increased the stiffness of the binding, increases response, and is adjustable to help you dial in the perfect fit.

Grade 8.8 Hardware:

Union ensure their hardware is reliable by using the strongest steel available on the market.

Tool-less strap adjust:

Whether you're letting a friend borrow your bindings or you just need to fine tune your fit, you can adjust your straps on the fly without the need for tools.
