Duotone Downwinder Slim SLS 2025 Foilboard

The Duotone Downwinder Slim SLS 2025 Foilboard is Duotone's high-performance shape for downwind foiling and paddle foiling in bigger, faster swell, a long, narrow outline built for open ocean rather than small bumps. It's the board for riders chasing speed and glide once conditions properly turn on.

  • Downwind foiling and paddle foiling in bigger, faster swell
  • Carbon Custom Sandwich construction
  • Long, narrow outline, low rocker, pin tail
  • Single concave bottom
  • Recessed deck
  • Long carbon foil tracks
  • For intermediate+ to advanced riders

Performance & Feel

The long, narrow outline and low rocker get the Downwinder Slim SLS up to speed fast, built to paddle or wing into faster rolling open ocean swell rather than smaller bumps. The pin tail and single concave keep touchdowns clean, with strong recovery when you come down hard.

Pronounced rail bevels through the back of the board give confident, stable release the moment you're up, and the recessed deck keeps you close to the foil for a direct feel through turns and at speed.

Carbon Custom Sandwich construction keeps the board light and stiff, and the long carbon foil tracks give you room to fine-tune foil positioning, opening the door to smaller, faster foils once you're moving.

Three sizes cover the range. The 7' 6" is the most nimble, the 8' 0" sits in the middle as the versatile choice, and the 8' 6" adds stability for bigger riders. It comes up to foil with confidence despite the narrower shape and is a board built for riders chasing bigger bumps and faster swell rather than those just starting out.
