DUOTONE SLS COSMIC SUP BOARD (COMING SOON)

The DUOTONE COSMIC SLS is the all-wave SUP hardboard built for serious wave performance. Its round-point nose delivers stability and clean entry, while the pulled-in moon tail keeps you responsive when it matters. The bottom shape is engineered for speed: mono-concave up front generates effortless glide through weaker sections, transitioning to double-concave mid-board for maximum stability, then opening into a V-tail that releases water cleanly for snappy pivots and fluid turns. The game-changer is the 4+1 fin box system. One board, four setups. Run it as a thruster for balanced all-around performance across all conditions. Switch to quad for maximum grip and hold in critical, powerful surf. Go twin for ultimate looseness and flowing arcs in smaller, softer waves. Or twin + trailer for those in-between days when you need just enough control. Built with Biax-Composite-PVC Sandwich construction, every EPS foam core is individually CNC-milled for precision. The result is a board that's lighter and stiffer than standard semi-custom production, with a custom laminate layup optimised for your size. Light where it matters. Strong where it counts. Designed for newcomer through advanced SUP surfers who want one board that genuinely replaces a quiver. If you've been searching for versatility without compromise, this is it.
