2026 Duotone Paradox SLS | 75L Carbon Mid-Length Board Tested and Reviewed

The 2026 Duotone Paradox SLS is Duotone's latest mid-length board, built primarily for parawinging, with strong crossover appeal for wing foiling, light-wind sessions, and even prone or Foil Drive setups. Tucker breaks down his time on the 75L, 5’9” by 20-inch version, covering why this efficient shape builds speed so well off the water and helps your foil lift off without a lot of upward pull from the parawing. In this review, we cover the SLS carbon construction, the planing hull and double-concave bottom, the kick tail and rail chines, the flat rocker underfoot, the V-strap deck layout, and the automatic Gore-Tex air vent. Tucker shares honest sizing guidance for riders around 90 kilograms, where this board shines, and where he would size up or down based on wind and skill level. He also compares it to the KT Arc, a longtime shop favorite, and points out one small detail he wishes Duotone had refined on the rail. Whether you want a true one-board quiver for winging and parawinging or a compact, high-volume option for lighter days, the Paradox SLS covers a lot of ground.
