What Our Gearhead® Experts Are Saying: "These are my go-to splitboard bindings when I want to move fast and stay light. The carbon highbacks give me tons of response, and the Pebax straps stay flexible even when it’s bitter cold. Touring feels smoother than ever with the ST tech—transitions are quick, and climbing feels efficient." We love how the Spark R&D Arc ST Pro Bindings blend lightweight design with dependable backcountry performance. By combining carbon-reinforced highbacks and Pebax straps, these bindings shave grams without giving up the power or durability needed for serious missions. On the skintrack, the Smooth Touring upgrades make transitions seamless, climbing efficient, and long approaches feel less taxing. The CNC-machined baseplate cuts weight without compromising strength, while overmolded thermoplastic bushings reduce friction for buttery-smooth touring. Pebax Pillow Line straps, custom hardware, and 7075 aluminum heel loops round out a setup that feels precision-built for splitboarders who demand the best. Whether we’re chasing powder stashes in the trees or laying down surfy turns in big alpine terrain, the Arc ST Pro keeps us moving fast and riding free.
