Abstract
A face mask for pressure breathing. The mask has a body with a sealing boundary shaped to fit over the bridge of a wearer's nose, downward past the sides of his nose and mouth and across his mental protuberance. The sealing boundary includes a reflective primary seal and a secondary seal. The reflective seal lays flexibly against the wearer's face. The secondary seal is relatively rigid relative to the reflective seal so as to indent into the face when pressed against it in order to respond to stringent conditions of g forces and differential pressures.
