Re-designed for 2025 by the Spencer brothers, Finn and Jeffrey, the new Downwinder SLS shapes are fine-tuned for enhanced glide and take-off efficiency, while maintaining relatively compact dimensions with exceptional stability - perfect for SUP Downwinders in smaller and steeper bumps or for light wind Wing Foiling. The shapes are two inches longer and half an inch narrower compared to the previous models, offering efficient glide and quick acceleration from learner to advanced Downwind enthusiast. The Downwinder SLS features a low rocker and a sleek pin tail, ensuring the earliest take-off. The clean bottom contours with a single concave entry facilitate uninterrupted touchdowns, while the pronounced rail bevels with hard edges in the rear half of the board provide excellent release and stability. The slightly recessed deck enhances your connection to the foil and the new, longer carbon foil tracks provide adjustability for all types of foils while also saving weight. The Downwinder SLS comes in three dedicated shapes: the compact 7’0’’ x 19.5’’ (95l), the versatile 7’6’’ x 20.5’’ (115l), and the stable 8’0’’ x 22’’ (135l). Built with our lightweight Carbon Custom Sandwich technology, the Downwinder SLS combines stability for quick progression with dimensions perfect for SUP Downwinders in smaller bumps and Wing Foiling in lighter winds.
