Windsurf board Duotone Ultra Grip (Quad) SLS 2026 yellow

The Ultra Grip (Quad) SLS is Duotone’s most radical wave board, developed together with PWA athletes. Its SLS construction combines lightweight and stiffness at the highest level, creating a direct, responsive feel underfoot and instant reaction to every input. Being 1–2 cm wider than most wave boards, it offers the stability of a board 5 liters bigger while the increased outline curve makes it turn as radical as a board 5 liters smaller. The segmented 3-stage rocker makes bottom turns easier off the front foot and supports tight back-foot top turns, while the progressive tail kick ensures instant acceleration and clean release. The Synced Curves Concept aligns outline, rocker and rails, resulting in a predictable and natural riding experience. Designed for ground swell and open-ocean conditions, the Ultra Grip (Quad) SLS excels at spots like Maui, Cabo Verde, Mauritius, Chile or Ireland.
