Abstract: A headgear accessory is adaptable to an existing cap, hat, hood, or other article worn on the head, to cover a hole or passage formed therein to provide for the passage of the hair of the wearer therethrough. Using the present headgear accessory, a hole may be placed in the headgear at a location comfortable for the passage of longer hair (e.g., ponytail, braid, etc.) therethrough, and the accessory sewn or otherwise secured to the headgear to provide a decorative closure for the hole. The accessory is preferably formed of a resilient, flexible material such as neoprene sheet, with a synthetic fabric overlay for additional strength and to provide a more attractive appearance. A series of slots are formed in the neoprene/fabric sheet, through which the wearer's hair is passed.
