Main Information

Union Charger

Fast transitions. Unmatched ride feel. The Union Charger has quickly become the go-to splitboard binding for riders around the world. Designed for speed and simplicity, the Charger’s innovative Dual-Lock system makes switching from tour mode to ride mode fast and frustration-free—no matter the conditions. Built tough for big missions and long seasons, it delivers the comfort, performance, and board feel Union is known for.

Whether you're chasing powder lines or tackling technical ascents, the Charger is ready when you are. Make the switch and feel the difference on the descent.

Included in the box: Mounting hardware, Charger split disk with magnesium adapter plates, touring brackets, and splitboard strap.

Riding Category
Freestyle Rating: Freestyle bindings are designed for riders looking for the ultimate freedom, comfort and that “loose truck” feel. These bindings are generally best suited for riding park or riders looking for a more soft and surfy board feel.

All Mountain Rating: All Mountain bindings are generally mid-flexing and built to handle all terrain and all riding styles.

Performance Rating: Performance bindings are stiffer, provide instant edge-to-edge response, and the most stable board connection possible. Performance bindings are generally best suited for high speed carving or ridding steep technical terrain.

Freeride Rating: Freeride bindings are built for off-piste exploration, deep powder, and challenging backcountry conditions. They combine support, comfort, and responsiveness, allowing riders to tackle variable snow and steep terrain with confidence.

Union Bindings come in a variety of flex ratings. The baseplate, highback, straps, bushing and disk all have different stiffnesses to help give a specific ride feel and function. Softer flexing bindings are generally used for more surfy or freestyle riding, while stiffer bindings are generally used for more hard charging and responsive freeriding.
