Abstract: A cover for covering a headgear closure strap provides easy detachable securing of the hat to a magnetic surface, by including a magnet within the cover. The cover includes a cover body that encircles a cross-sectional profile of the headgear closure strap and extends along at least a portion of the extension of the headgear closure strap, a magnet disposed inside of the cover body behind a rear outer face of the cover body when the cover is installed on headgear, and a fastening mechanism for securing a top and a bottom wrap portion of the cover body together in front of a front inner face of the cover body when the cover body is installed on the headgear. The cover body may be formed from a sheet of flexible material with an edge folded over and fastened to form a pocket to retain the magnet.
