Abstract
Abstract The invention relates to an inexpensive, disposable liner for hard hats. The liner is shaped to be inserted into and resiliently engage the lower periphery of a hard hat. The liner includes an elastic band attached to the lower edge of the liner so that the liner can be slipped over the beak and the interior support of the hard hat. The liner is preferably made of a soft, breathable material which will prevent the buildup of moisture, and which will feel comfortable to the user. The sides of the liner are elongated so that the liner can be folded over the lower periphery of the hard hat. The elastic band attached to the lower edge of the liner allows the liner to be easily installed into and removed from the hard hat.
