Duotone Cosmic SLS Rigid Paddleboard. This is the SUP wave hardboard that handles everything, and helps you push your surfing further.
FULL DESCRIPTION
Duotone Cosmic SLS Rigid Paddleboard ... A round‑point nose provides stability and clean wave entry even at low paddle speed, while the pulled‑in moon tail keeps the board tight, reactive, and precise when the wave demands it.
The bottom contours define the ride: a forward mono‑concave delivers instant speed and keeps the board lively through weaker sections. It transitions into a double‑concave mid‑section for maximum balance and stability. Toward the tail, an opening V releases water efficiently, freeing the tail for quick pivots and that loose, flowing sensation at the end of every turn.
Accelerate. Drive. Release. Repeat. Duotone Cosmic Rigid Paddleboard
The COSMIC is designed for intermediate to advanced SUP surfers who take wave performance seriously
FULL CUSTOM SLS Construction
Strong. Light. Superior.
Built with Biax-Composite-PVC Sandwich technology, every EPS foam core is individually CNC-milled — not pressed into a mould. The result is a board that is lighter and stiffer than anything made using standard semi-custom production, with an individual laminate layup optimised for each size. Light where it matters. Strong where it counts.
4+1 Fin Box System — Unmatched Versatility
Four multi-fin boxes plus a central US box make the COSMIC SLS genuinely four different boards in one.
Thruster (as delivered) — Balanced all-around performance from waist-high to well overhead. The universal setup: precise, controlled, and high-performing across all conditions.
Quad — Maximum grip. Four fins deliver maximum grip and lateral hold for critical, powerful surf where traction is everything.
Twin — Ultimate looseness. The skatey, flowing twin-fin feel for smaller, softer surf. Draw long arcs or snap hard pivots — the board breathes and surfs with a freedom no other configuration can match.
Twin + Trailer — A 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.
Who is the COSMIC SLS for?
The COSMIC SLS is built for newcomer to intermediate to advanced SUP surfers who are serious about wave performance. 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.

The COSMIC is built using DUOTONE’s CUSTOM CNC composite construction — a composite‑wood sandwich layup around a lightweight, CNC‑shaped EPS core with a clean, unfinished aesthetic. Developed and continuously refined through DUOTONE’s long heritage in premium windsurf and foil board manufacturing, this construction delivers an ideal blend of low weight, efficient glide, and exceptional comfort.
