Component Breakdown
S4 Duraflex ST Baseplate
Quick edge-to-edge power and a locked-in ride feel. The S4 Duraflex ST baseplate is Union's go-to for anything and everything you can throw at it — and it's backed by a lifetime warranty.
S1 Duraflex ST Highback
The perfect balance of flex and response for all types of riding. The S1 Duraflex ST highback is a time-tested classic and a favorite of Union pro riders — proven geometry, reliable feel.
ExoFrame 4.0 Ankle Strap
ExoFrame 4.0 ankle straps provide a secure and locked-in ride feel. Lightweight, super durable, and a team and shop favorite — the step up from the entry-level ExoFrame 3.0.
TS 2.1 UltraGrip Toe Strap
Multi-positional options and thermoplastic anti-slip material keep you locked in and on point. Compatible with any snowboard boot shape on the market.
Magnesium S1 Ratchets
The all-new Magnesium S1 ratchets are Union's answer to the elements. A fully integrated spring protected from the harsh outside gives you fast, fail-free 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 Trilogy Classic is built to last seasons of progression.
Multi-Density Thermoformed EVA Bushing
Multi-density thermoformed EVA absorbs impacts and reduces vibration across the entire footbed, delivering enhanced comfort and control underfoot.

The strongest steel available on the market. Comes pre-installed so you can mount and ride without a hardware run to the shop.
