Union Trilogy Women's Snowboard Binding
The Union Trilogy has for years been one of the most popular women's bindings in the Union range. This versatile all-mountain binding is designed for female snowboarders who want to perform on any terrain without compromising on comfort, support, or control. Whether you're carving smooth turns on the piste, surfing fresh powder, or seeking natural features on the mountain, the Trilogy provides the reliability and performance you need to ride with confidence.
The foundation of the Trilogy is formed by the durable Stage 9 Duraflex ST baseplate. This lightweight construction offers an excellent balance between stability and board feel, so your snowboard responds immediately to every movement. Thanks to its balanced medium flex, the binding feels both forgiving and responsive. This makes the Trilogy suitable for a wide range of riding styles and conditions, from relaxed cruising to more technical descents.
For additional support, the binding is equipped with the S19 Duraflex ST highback. This highback is specially designed for female riders and offers a perfect combination of comfort and control. The ergonomic shape follows the natural contours of the legs, reducing pressure points and keeping long days on the mountain comfortable. At the same time, the highback provides enough responsiveness for quick turns and powerful descents.
In terms of comfort, the Trilogy is also among the very best. The Exoframe 6.0 ankle straps enclose the boots firmly and evenly, preventing pressure points and optimizing energy transfer. The TS 5.0 toe straps provide a reliable fit and keep your boots perfectly in place, regardless of conditions. Thanks to the high-quality magnesium ratchets, the straps are smooth to adjust and remain dependable season after season.
Under the binding, the integrated Molecular Bushing damping system provides excellent shock absorption and vibration damping. This effectively cushions hard landings and terrain irregularities while preserving board feel. That results in more comfort, less fatigue, and extra confidence during long days on the mountain.
With its combination of versatility, comfort, and proven performance, the Union Trilogy is an excellent choice for female snowboarders looking for one binding for all conditions. From first chair to last run, this binding provides the support and reliability to make the most of every day on the mountain.
