Arc ST Pro Bindings - 2025

What Our Gearhead® Experts Are Saying:

"The Arc ST Pro Bindings are crazy light yet super durable, and they have all the performance features I look for in backcountry bindings. They have great heel response, an easy transition system, and the Pillow Line straps keep everything comfortable. Plus, with the weight savings, I don’t feel weighed down even on long ascents!"

Designed with premium materials and dialed-in tech, the Spark R&D Arc ST Pro Bindings are made for splitboarders who push limits. These bindings build upon the proven Arc ST foundation, but the Pro Series goes even further, incorporating ultra-light components that maximize performance and minimize weight. At only 1.25 lbs per binding, they feel like an extension of our boots, keeping us nimble and energized on every climb and descent.

With features like the ST Tech for powerful response, T1 binding system for seamless transitions, and Tesla Snap Ramps, these bindings deliver high performance in a compact design. The Asym Highbacks provide just the right flex, and the Pillow Line Straps with a flex window offer secure comfort as we ride through powder and technical terrain. For every splitboard mission, the Arc ST Pro Bindings let us go lighter, farther, and faster without sacrificing control.
