Component Breakdown
S9 Duraflex ST Baseplate
Built with a purpose. The Trilogy's S9 Duraflex ST Baseplate offers Union's highest levels of strength and energy transmission to date. Backed by a lifetime warranty, this is the same flagship baseplate as the men's Force — the strongest and most responsive in Union's lineup.
Team Highback
Durable construction built for the Trilogy's pro team riders (Jamie Anderson and Mia Brookes). The Team Highback provides a balanced flex profile that's responsive enough for charging yet forgiving enough for all-mountain freestyle — a women's-specific design tuned for the way women ride.
ExoFrame 6.0 Ankle Strap w/ PU Core
Padded comfort meets instant response. The ExoFrame 6.0 Ankle Strap features a PU core that wraps over the edges of the ExoFrame for a secure, locked-in ride feel. Lightweight, super durable, and the premium ankle strap in Union's lineup.
TS 5.0 UltraGrip Toe Strap
The TS 5.0 UltraGrip Toe Strap easily shapes to any snowboard boot and offers maximum grip from all angles. Multi-positional adjustment for the perfect fit on any boot shape.
Magnesium S2 Ratchets
Magnesium S2 ratchets are Union's answer to the elements. A fully integrated spring protected from the harsh outside provides you with Union's best-in-class ladder action run after run — the lightest and most durable ratchet in Union's lineup.
Extruded 3D Aluminum Heelcup
Designed for optimum heel hold and minimization of drag. Backed by Union's lifetime warranty — the core of every Trilogy is built to last.
Non-Stick HP EVA Footbed
The next evolution of Union's non-stick EVA technology. Non-Stick Hot Press EVA creates a closed cell finish that's 100% waterproof. Gone are the days of the base being saturated after a full day in the snow.
Molecular Bushing Suspension System
Union's Molecular Bushing Suspension System acts as an additional layer of dampening and shock absorption between you and your snowboard. Reduces chatter on hardpack and softens big-mountain landings — the same premium bushing as the men's Force.
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.
