2026 Downwinder Slim SLS

Performance & Feel

Duotone has pulled the outline in another half inch per size from the previous Slim SLS, cutting resistance further and getting you up to speed faster, even on smaller foils. Tail rocker adds clearance when pumping and helps the board release cleanly into take-off rather than catching.

The mono-concave base keeps glide clean and touchdowns smooth, holding forward momentum rather than losing it on recovery.

Carbon Custom Sandwich construction keeps the board light and stiff without adding weight, and the long carbon foil tracks give you room to dial in foil placement for whatever setup you're running.

Three sizes cover the range. The 7' 6" is the most nimble, the 8' 0" sits as the versatile middle ground, and the 8' 6" adds stability without giving up much of the outline's efficiency. It's a board for riders who've got some downwind or light wind foiling under their belt and want the refinement this board brings
