Downwinder Slim SLS

Sizes: 7'6" / 8'0" / 8'6"

SUP Downwind

Agile and responsive, like your neighborhood hero (except for the beach). The Duotone Downwinder Slim SLS is tuned for speed, efficiency, and gliding prowess. Its narrower outline accelerates quicker, paddles faster, and makes take-offs smoother than previous models. The 7'6" is compact and nimble, the 8'0" has the "just right" of control, and the 8'6" offers more stability for bigger riders and those just starting out.

What is SLS Construction?

For Duotone, SLS bridges the gap to better facilitate wing foiling. Based on their previous windsurf board designs, the SLS design sees a Carbon PVC Sandwich layup with a light EPS core. This combination of durability and a light weight leads to a board that is coveted by team riders and those who demand more out of their landings and jumps.
