Abstract: A method of constructing a reduced drag wing, including: providing a top wing surface panel; coupling a top surface external leading-edge panel to the external surface of the top wing surface panel, wherein the top surface external leading-edge panel extends forward from the top wing surface panel and extends rearward covering at least partially the top surface external leading-edge panel; coupling internal rib elements to the interior surface of the top wing surface panel; coupling the top surface external leading-edge panel to a sleeve element; coupling the rear sleeve element to a bottom wing surface panel; coupling the internal rib elements to the interior surface of the bottom wing surface panel; and coupling the top surface external leading-edge panel and the sleeve element to a releasable mechanical mechanism. A reduced drag wing for a wingsuit. A wingsuit including a reduced drag wing.
