- resilient means for holding the inner mask in position when in use;
- and a member attached to the inner mask which extends at least the width of the head of a wearer of the apparatus and which is at least semi-rigid so as to urge the inner mask against the wearer's face when the apparatus is worn whereby the semi-rigid member serves the dual function of maintaining the hood away from the wearer's face as the apparatus is donned and urging the mask against the users face once the apparatus is in place on the wearer's head.
