Abstract
An inflatable hat provides a concave pocket constructed of flexible material that opens to freely receive the user's head in the manner of a conventional hat by virtue of supports resisting the outward extension of the pocket when the hat is inflated. In one embodiment, the pocket is a cylindrical tube extending between parallel walls of the hat structure. A bowing in of the tube provides varying sizes of hat openings depending on the amount of inflation to provide a comfortable fit to different users.
