Duotone Foilboard Downwinder Slim SLS - 2026

The Downwinder Slim SLS from Duotone is developed for speed, precision, and efficiency in Downwind SUP Foiling, with additional suitability for light wind Wing Foiling. The refined, slimmer outline enhances paddle speed and reduces resistance, improving glide and making take-offs more efficient. Each size is reduced in width by 0.5 inch compared to standard Downwinder shapes, contributing to a more streamlined performance profile.

A clean monoconcave bottom maintains speed and supports smooth touchdown recovery, helping preserve forward momentum. Tail rocker improves release and increases clearance during turns and pumping, ensuring controlled transitions. Long Carbon foil tracks provide extensive trimming options and compatibility across foil setups, allowing riders to fine-tune positioning.

Constructed using lightweight Carbon Custom Sandwich technology, the Downwinder Slim SLS balances durability with minimal weight for responsive handling and agile performance. The range is suited to dedicated downwind riders as well as those exploring light wind wing foiling applications.
