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.
