The most lightweight and high performance splitboard bindings in the world.

Made with extreme attention to detail, premium materials, and custom components. Our PRO Series bindings are the culmination of our years in the forefront of splitboard binding technology and manufacturing. We build these for splitboarders who want the best of the best.

Carbon reinforced nylon highbacks
More responsive, lighter, and stiffer than our standard glass reinforced highbacks. Injection molding allows for more complex geometry and improved impact strength compared to other methods of carbon fiber construction.

Full Pebax® plastics in Pillow Line straps, ladders, & adjusters.

Pebax is a premium material most often found in high-end ski boots as it provides consistent stiffness and improved toughness in cold temperatures. It’s also 20% lighter than our standard material.

7075 Aluminum
Heel Loops
Thinner and lighter than our standard heel loop while maintaining the required strength.

Every Gram Counts

Pro aluminum hardware replaces 7 stainless steel components for a 65% hardware weight savings.

Custom made hardware allows us to add splitboard specific features like hex heads for less strippage and hollow pivot pins for weight savings. The heel loop screws got the best makeover of all with a custom screw head with double the drive depth and an unthreaded shoulder to improve connection to the heel loop.
