Utilized throughout the SlingWing V4’s airframe, this high-tenacity polyester features biaxial gridding and extensive emulsion coating, eliminating stretch in all directions while providing a more balanced feel, better power control, and stable, effortless luffing while surfing. The stiffness of FrameLite’s unique 2x2 weave structure significantly reduces elongation of the airframe and increases multi- season durability. At 160 grams per square meter, FrameLite uncompromisingly offers the optimum balance of flex, strength, stiffness, and weight.
