Abstract
A full breathing mask including an inner face mask and an outer face mask. The outer face mask includes a basin-shaped intermediate wall which extends from the inside of the outer face mask and which has a free end, a con-cave side, which is intended to embrace and lie in abutment with the wearer's chin part, and a convex side. At least substantially the entire perimeter of the inner face mask is adapted to lie against the wearer's face.
