Abstract: A headgear accessory encompasses and encases the edge of a brim typically found on headgear such as a baseball cap. The elastically pliable band slips over and engages the upper and lower surfaces of the brim of a hat, encompassing the forward edge of the brim, and extending longitudinally along the curvilinear length of the brim. A channel runs the longitudinal length of the band which includes an area void of material and is configured to accept and secure the edge of the brim. As the surfaces of the channel expand apart to accept the edge of the brim, the brand is elastically deformed creating a normal force between the band and the respective surfaces of the brim. The normal force combined with the applicable coefficient of friction and other mechanical/structural configurations results in a frictional force that secures the band to the brim of the headgear.
