Union Charger Splitboard Bindings 2025
The 2025 Union Charger represents the pinnacle of splitboard binding engineering for riders who refuse to compromise downhill ride feel for uphill efficiency. Built around Union’s game-changing, pinless Dual Lock System, the Charger eliminates the slop and dead spots traditional splitboard bindings create underfoot. By allowing your splitboard to flex naturally beneath your feet on the descent, it delivers an authentic, solid-board ride feel while making tour-to-ride transitions lightning fast.
Milosport Shop Take
"If you hate fiddling with pins, alignment clips, or stiff, dead-feeling splitboard bindings on freezing cold ridges, the Union Charger is an absolute game-changer.
Sitting at a responsive 7/10 flex rating, this binding drives power into your edges on icy traverses and steep Wasatch descents without feeling like an unforgiving brick. The magic is in the Dual Lock system—you simply rotate the binding into place on the charger disc and throw down the single rear lever to lock in. Downhill, it feels shockingly close to a high-end Union Force or Atlas resort binding, giving you natural deck flex, deep chatter absorption, and zero lateral slop."
