Abstract
An improved protective face mask periphery includes an inturn having a flat ortion extending inwardly of an inner surface of the face mask, and a curved bubble portion which is concave with respect to the inner surface of the face mask and which curves outwardly into engagement with the wearer's face. The face mask periphery thus forms a good seal with the wearer's face while at the same time being comfortable to wear.
