Duotone E_Pace SLS - based on the incredibly versatile original E_Pace the goal for the SLS version was to achieve a racier feeling combined with improved acceleration and power compared to other no-cam freerace sails. A weight reduction of a whopping 500 g made the E_Pace SLS the lightest no-cam freerace film sail on the market. Achieved with unique one-piece sleeve and single layer high-tech reinforcement patches replacing the usual 5-layer patches. However, the thickness of the panels has not been reduced resulting in the E_ Pace SLS having the best low weight vs. strength ratio on the market.

A more forward oriented draft position gives the E_Pace SLS a racy feeling very similar to the S_Pace or Warp. To prevent this forward motion from creating a catapult tendency, the leech is slightly more open which also improves the high-end control (= v-max). The intelligent use of Carbon X-Ply in the high load clew and top area results in the most effective conversion of wind energy into forward motion. However, the slightly more (re)flexing regular X-Ply in the body avoids the power from becoming uncontrollable. A common characteristic from many other no-cam freerace sails is to significantly compromise low-end performance in search of top end speed. To avoid this Duotone increased the pre-shaping of the sail which improves the acceleration and power despite the opened-up leech.
