Duotone Cosmic SLS

The Duotone Cosmic SLS (Strong-Light-Superior) is the crown jewel thanks to its premium Innegra Carbon and vacuum PVC sandwich construction. Each core is individually CNC-milled (not molded), achieving maximum structural rigidity and an ultra-reduced weight for competition-level surfing. The Duotone Cosmic is a true revolution for SUP Surfing. A completely new design, born from cutting-edge technology, for riders looking for radical wave performance without losing paddling ease and stability in the lineup.

Its shape, fully optimized using artificial intelligence, makes this board the ideal choice if you want to replace multiple models in your garage with a single "All-Wave" board that works flawlessly in both small waves and powerful, fast overhead walls.

Thanks to Duotone's new design concept, the boards are slightly shorter and more compact, drastically reducing swing weight during turns. However, they maintain a cleverly distributed volume and a refined rail design that provides the stability of a board with 10 liters more volume, but with the turning responsiveness of a board 10 liters smaller.

Duotone Cosmic SLS Features:

• SLS Construction: Premium Innegra Carbon and vacuum PVC sandwich construction, giving SLS (Strong-Light-Superior) boards next-level lightness and durability.
• Bottom Design: Starts with a deep single concave in the nose area to generate instant speed and keep the board alive in flat sections. In the center, it transitions into a double concave that maximizes control and stability.
• Synced Curves Concept: A perfect mathematical blend of outline, rocker line, and rail curvature designed via AI-guided CAD software for a fluid rail-to-rail movement.
• Rounded Nose: Provides outstanding stability when paddling into the wave, allowing for an easy take-off even at low paddling speeds.
• Tapered Moon Tail: A narrow, sharp tail that delivers total grip in the most critical and tight turns.
• Thin Rails: A lower profile on the sides for direct control, allowing you to engage the rail with less effort and initiate turns immediately.
• Versatile Fin Setup: Includes a 4+1 fin box system (Multibox + US center box). This allows you to ride it as a Thruster (balance and control), Quad (maximum grip in powerful waves), or Twin-fin (loose, surfy feel in small waves).
• Ledge Pro Handle: Ergonomic and integrated for comfortable transport to the beach.
