Component Breakdown
S11 Duraflex ST Baseplate
By removing excess material in the toe and heel of the baseplate and utilizing an asymmetrical shape, Union drastically reduced weight without sacrificing strength — and paired it with their next-generation suspension bushing for unmatched dampening.
All-New Highback Design
Engineered for next-generation suspension — the shape and flex profile deliver smoother response and better edge-to-edge power transfer than previous Union highbacks. Pro team tested by Arthur Longo and Gigi Rüf.
Hybrid 1.0 Ankle Strap
Instant response meets all-day long foot comfort. The Hybrid 1.0 combines Union's responsive ExoFrame exterior with a comfort-focused interior — best of both worlds for riders who want power without pressure points.
TS 5.0 UltraGrip Toe Strap
Multi-positional options and thermoplastic anti-slip material keep you locked in and on point. The TS 5.0 UltraGrip easily shapes to any snowboard boot for maximum grip from all angles.
Magnesium S1 Ratchets
Magnesium S1 ratchets are Union's answer to the elements. A fully integrated spring protected from the harsh outside gives you Union's best-in-class ladder action run after run.
Extruded 3D Aluminum Heelcup
Designed for optimum heel hold and minimization of drag. Backed by Union's lifetime warranty — the core of every Ultra binding is built to last.
Duraflex + ExtraGrip Footbed
Duraflex footbed with ExtraGrip rubber sections — Union-exclusive bushing system that adds another layer of dampening and shock absorption between the baseplate and your boot.
Integrated 2-Stage Forward Lean Adjuster
Fine-tune your forward lean angle with a #3 screwdriver to match changing terrain and riding styles. On-the-fly adjustability without removing the binding.
Grade 8.8 Steel Hardware
The strongest steel available on the market. Comes pre-installed so you can mount and ride without a hardware run to the shop.
