Abstract
An athletic garment including a panel designed to reduce frictional and pressure drag around an appendage of an athlete competing in a high-speed event, such as running and cycling. The panel is positioned to encircle the appendage, and is provided with regions having different surface texture roughnesses. The leading edge of the panel includes texture designed to enhance the laminar boundary layer, while the adjacent portion of the panel includes texture intended to trip the boundary layer to turbulent flow. The drag-reducing panel may be the cuff of a sock, a sleeve, wristband, a headband, or the like.
