Duotone Downwinder Slim SLS Foil Board 2026

The Duotone Downwinder Slim SLS 2026 is built for speed, glide, and efficiency, making it the ultimate board for downwind SUP foiling, lightwind winging, and open-water adventures. Designed with a slim, elongated outline and lightweight carbon construction, the Downwinder Slim SLS delivers effortless take-off, maximised glide, and stable handling even in tricky ocean conditions.

Its narrower stance area and recessed deck bring the rider closer to the foil for a more connected, controlled feel. The elongated waterline provides unmatched glide for catching bumps and downwind runs, while the nose rocker and refined rails ensure smooth touchdowns and efficient release. With SLS carbon construction, the board is strong yet lightweight, perfectly balancing performance and durability.

Why It Stands Out

The Duotone Downwinder Slim SLS 2026 is the go-to board for riders seeking glide, speed, and efficiency over distance. Whether you’re chasing downwinders, connecting bumps, or winging in light winds, the Slim SLS design ensures maximum performance and confidence in open-water conditions.
