Exciting news! DUOTONE SUP have launched a new line of composite boards and the first in the line-up is the dedicated surf SUP, the all new Cosmic SLS 💥
💫 Made to Ride It All. One board - Every wave. Designed for intermediate to advanced SUP riders who are serious about SUP performance. You may want to charge powerful overhead surf one day and tear apart playful beachbreaks the next. This is the SUP wave hardboard that handles everything. If your quiver currently contains multiple boards for different conditions — or if you‘ve been searching for one board that can genuinely replace them — this is it.
💫 SLS (Strong. Light. Superior. ) construction, developed and continuously refined through DUOTONE’s long heritage in premium windsurf and foil board manufacturing, delivers the ideal blend of low weight, efficient glide, and exceptional comfort.
💫 4+1 Fin Box System gives unmatched versatility. Four multi-fin boxes plus a central US box make the COSMIC
SLS genuinely four different boards in one.
-Thruster: Balanced all-around performance, precise, controlled, and high-performing across all conditions.
- Quad: Maximum grip and lateral hold for critical, powerful surf where traction is everything.
- Twin: Ultimate looseness. This gives the skatey, flowing
feel in smaller, softer surf. Draw long arcs or snap hard pivots.
- Twin+Trailer : The small center fin adds just enough grip and direction to the twin setup for those in-between conditions where a little extra control makes all the difference
