Abstract
Abstract A head covering of two sheets, not necessarily separate, of material joined along all edges except the bottom to slip loosely over the wearer''s head and provided with an opening for the wearer''s eyes, nose, and mouth. A mask is attached to the head covering to cover the nose and mouth area and define the lower edge of the eye opening. One or more fasteners from opposite sides of the mask are adapted to be looped behind the wearer''s head when the head covering is in place, thereby securing the mask snugly over the wearer''s mouth and nose and simultaneously causing the head covering to be held in place over the wearer''s head and hair.
