2025 Duotone Crush SLS Prone Surf Foil Board

SLS stands for Strong Light Superior and is your gear that empowers you to push your limits and strive for peak performance without compromise.

With a flat rocker for easy paddling and a raised nose to prevent catching on the water, this board is made to get you into waves you normally wouldn’t think of surfing. Its wide tail and nose provide exceptional wave catching ability and ease of use during touchdowns and in whitewater, ensuring a smooth and controlled ride.

The Crush SLS features cut-outs in the tail for early release and a single concave to flat bottom shape for maximum paddle speed and glide. Additionally, the slightly raised front foot angle increases responsiveness while maintaining pumping efficiency, allowing for precise maneuverability, and effortlessly linking waves.

Coming in two sizes: 4’6” with 30l and 4’10” with 40l – The 4’6’’ has enough volume and paddle speed for intermediate to experienced surfers to catch the smallest waves, while the 4’10’’ is the ideally suited for slightly heavier riders to paddle into even smaller rollers.

With its volume distribution, flatter rocker, and our SLS construction, the Crush SLS is all about easy entry into waves. With a perfect combination of stability, glide, and responsiveness the Crush SLS is the ultimate board for Prone Foiling enthusiasts looking to take their skills to the next level.
