The Union Ultra Snowboard Binding is one of Union’s most comfortable women’s designs. It’s a medium-flexing binding known for its freestyle performance. The Ultra features an S11 ASYM Duraflex ST Baseplate. Non-stick and Extragrip material cover the baseplate disk. The S11 Ultra Duraflex ST Highback is perfect for freestyle snowboarding (it does not have a Forward Lean Adjust). The heel cup on the Ultra Binding is made with Extruded 3D Aluminum and features an Astro Washer, which prevents heel cup slippage and enhances performance. On the bottom, you’ll find a Union-exclusive Molecular Bushing with a TPE Outsole. The ankle strap on the 2025 Ultra has been updated to Union’s Hybrid 1.0 Strap. A TS 5.0 Ultragrip Toestrap finishes off the two-strap closure system. Both straps have a Tool-Less Adjust design and come with Magnesium S1 Ratchets with steel bases.
