The S-1 is the high performance 4 batten wave sail. The reduced batten count makes this sail light, flexible and responsive. Engineered for any type of conditions, this lightweight powerhouse redefines responsiveness. The S-1 has more back-hand pressure than the Blade, calibrated to go vertical or launch into aerial moves. A fat head on the latest generation S-1 opens more under load to increase the performance envelope; more high-end control and wind range. The aspect ratio has been decreased on the smaller sizes to reduce twitchiness. Combined with the fatter head, the area distribution is more obvious. The 025 S-1 utilises XFusion technology; ultrasonically welding the foot panels, negating the need for stitching. Lighter, more responsive, and no stitching to wear out. XFusion is an evolution of CarbonFusion technology used in the PRO sails that have trickled down to more accessible models. Both the S-1 and S-1 Pro are developed on an identical platform. The PRO construction offers the ultimate experience while the S-1 replicates the dynamic performance in a more accessible construction. Proprietary GRADIENT PANEL TECHNOLOGY reduces weight, increases strength, and controls stretch logically. Direct transmission of power. Increased longevity. The S-1 is built using premium materials. The S-1 features quality materials including VX2, SpiderFibre, and eM4. The S-1 Pro is crafted in CARBON FUSION. The S-1 is a manoeuvre-oriented wave sail to excel in waves from knee high to as big as they go.
