Abstract: A flexible weather-shield accessory that can be attached to any headgear, or in the absence of other headgear, that can be worn by itself on a user's head. The accessory has a body portion capable of shielding the wearer's neck and ears. This body portion includes a visor-covering area that can lie across the visor or forward extension of the brim of a hat, extending coverage forward of the wearer's face. Thus the accessory is also capable of shielding the sides of the face, including nose and chin. The accessory has an inner opening with a size-adjustment mechanism that allows for the insertion of, and releasable attachment onto, the crown of a hat, cap, or head. It can adjust to fit onto any size head or hat. Fasteners are located at the front lower edge of the accessory to enable the accessory to be loosely closed together below the chin and neck of the wearer, and alternatively, to allow the accessory to be fastened to the upper button and buttonhole of the wearer's shirt or blouse.
