Union Trilogy Womens Snowboard Bindings 2026

The Undisputed Queen of All-Mountain Performance. Bombproof Power Meets Precision Control.

As the premier women’s binding in Union's lineup and the top choice for world-class riders like Jamie Anderson, the 2026 Union Trilogy stands as the benchmark for all-mountain freeride and freestyle excellence. Built on Union’s legendary Stage 4 Duraflex ST baseplate and featuring a responsive, women's-specific highback, the Trilogy delivers instantaneous edge-to-edge response, high-speed stability, and unmatched durability. Whether carving steep Wasatch corduroy, dropping technical lines at Snowbird, or sending resort park jumps, this binding provides bulletproof performance for intermediate to expert riders.

Milosport Shop Take

"If you want the absolute gold standard in women's all-mountain bindings, look no further than the Trilogy. It is consistently our #1 selling high-performance women's binding at Milosport for a reason—it simply does everything with perfection.

Sitting at a dialed 7/10 stiff-responsive flex, the Trilogy gives you immediate drive when laying down carves or charging through variable chop, while remaining comfortable enough for all-day lap sessions. The Multi-Density Thermoformed EVA bushings underfoot absorb harsh landings and high-speed chatter, while the Exoframe 4.0 ankle straps lock your boot down with zero pinch points. Backed by Union's lifetime baseplate warranty, this is a binding you can trust in any terrain and any condition."
