Abstract: A sunshade for use with a hard hat to provide shade and ultraviolet protection for the wearer comprises a vinyl disk with a hole dimensioned to receive the crown of a hard hat, the disk being covered with a washable fabric and having an elastic band sewn to the covering at the hole. The diameter of the elastic band is smaller than the diameter of the hole so that, at the point of attachment to the covering, the band is stretched radially outward and defines thereby a first portion of the band on one side of the disk and a second portion on the opposing side. The first portion grips the crown of the hard hat above the brim and the second portion wraps around the underside of the brim. The sunshade typically ranges in size from at least 16 inches to 20 inches in diameter.
