Abstract
Abstract A flexible body portion covering substantially all of the face below the eyes of a wearer has nose and mouth openings. A flexible skirt affixed to the outer surface of the body portion along a seam which encompasses the nose and mouth openings and also at the tack points forms an air duct which directs expelled air and downwardly. In-turned flaps at the nose opening provide a seal around the wearer's nose. A stiff yet malleable arch affixed to the outer surface of the skirt prevent the mask from resting upon or rubbing against the wearer's nose. Broad lateral cheek rises provide vertical support.
