ABSTRACT:
A head covering is disclosed having a face mask portion and a rear portion which substantially completely surrounds the head of the wearer and reaches to the neck, where it may be gathered by a length of elastic, and which is formed of a laminated material incorporating, as a layer, a mat of generally discontinuous thermoplastic microfibers and, as a second layer, a web of continuous thermoplastic filaments, the laminated material providing a combination of bacteria barrier and air permeability properties substantially throughout the head covering which is effective for containment of bacteria while retaining air permeability sufficient to allow the wearer to breathe through the material in the face mask portion where the nose and mouth are covered.
