Injected EVA Bushings – The bushings dampen underfoot vibrations to promote a more comfortable ride and a smooth, even board flex with no dead spots.

Asym/Symmetrical Legacy Highbacks – Union has taken the Multizone Highback to the next level by combining the total freedom of movement you want in the air, with the strategic support you need to set down the landing gear. The women's-specific design is lightweight and more forgiving for optimal comfort.

Shift-on-the-Fly Forward Lean – Quick and easy to use, adjust the forward lean with a simple flip of a knob then slide it to wherever you want and re-lock it. Easily done while waiting in those pesky lift lines.

All-New Toe Cup Design – Holds better to your boots for consistent control and also moves vertically for multiple boot-to-strap positions. Female specific!

Extruded Anodized Aluminum Heelcups – The strongest and most versatile aluminum heelcup on the market, extruded aluminum comes out 100% pure and maintains its true shape no matter how much wear and tear you inflict. Also, every Union heelcup undergoes an anodizing process—reinforcing the already bombproof apparatus with 30% more strength.

Universal Disks – Compatible with any traditional 4x4 mounting system and 3-hole board patterns. Channel Compatible Discs are available separately from Union to fit Burton snowboards with The Channel.

Grade 8.8 Hardware – The most commonly used hardware is made from "mild steel" that has a property class of only 4.6. Considering how much stress a binding goes through, Union uses only the highest-strength steel, with a property class of 8.8.
