Abstract
A flexible full face mask to supply breathable air to humans when in environments where it is not possible to breathe, such as underwater masks, or in environments having toxic gases or similar toxic conditions. The mask includes a mask skirt in the form of a one-piece flexible face seal and separate rigid frame components which define separated self-contained spaces that are connected together in a manner to allow each self-contained space to individually conform and seal against the contours of the face of the wearer. The mask also includes a removable adaptor pod mounted on a lower of the frame components to enable full access to the mouth of the wearer while maintaining the mask in sealed relation on the facial surfaces of the wearer.
