Union Ultra Arthur Longo 2026 Snowboard Bindings

The Union Ultra is a binding designed for creativity, style, and flow. The 2026 Arthur Longo Pro Model takes that foundation and adds the unique aesthetic of one of snowboarding’s most stylish riders. With the same lightweight, freestyle-focused construction as the standard Ultra, this edition stands out thanks to Arthur’s signature design.

Freestyle Flow

Arthur Longo is known for making the mountain look effortless. The Ultra Pro Model captures that same spirit with a medium-soft flex that encourages freedom and expression. Whether you are buttering side hits, lapping the park, or carving with flow, the Ultra delivers the surfy feel and precise response needed for style-driven riding.

Built to Perform

Under the hood, this is still the Union Ultra. The Stage 11 ASYM Duraflex ST baseplate provides a lightweight and durable platform, while the S15 Ultra Duraflex highback ensures responsive yet tweakable support. Magnesium S1 ratchets are smooth, strong, and built for seasons of riding. It’s the kind of construction Arthur himself trusts.

Comfort That Supports Style

Style starts with comfort. The Ultra’s Forma X ankle straps and TS 4.0+ toe straps secure your boots while giving you the flexibility to tweak and press naturally. The EVA-padded footbed absorbs shocks and vibrations, so you can ride longer and stay comfortable in every condition.
