Abstract: The present invention describes a mask or goggles having a strap which includes a hair restraint mechanism for maintaining the hair of the wearer away from the wearer's face and/or equipment, while the mask is in place. The strap includes a central body which fits around the back of the wearer's head, fastening straps extending from the central body to attach the strap to the mask body and a hair restraint portion extending from the central body. Typically, the hair restraint portion is perpendicular to the central body and extends downward therefrom. The hair restraint portion includes a mechanism for fastening or securing it around the wearer's hair during use.
