Abstract
Abstract In accordance with the present invention, a liner for a hat, cap or similar head covering comprises a layer of moisture absorbent material which is backed by a layer of moisture impervious material. Further, adhesive means are provided for releasably securing the liner to the sweatband of the hat, cap or similar headgear. The bottom and side edges of the moisture absorbing layer are sealed to prevent the migration of moisture, oil, grease and other contaminants through these edges of the liner. The upper edge of the liner is left unsealed so that a wicking action encourages the transport of moisture from the body of the moisture absorbing layer to the top edge where it may be evaporated.
