A pleated, disposable, liquid-resistant face mask formed of a three-ply or four-ply composite laminate structure that is conformable to the shape of the wearer's face. The three-ply face mask has a first ply formed of a non-woven material, a carded cotton material, and a creped tissue wadding material; a second ply formed of a non-woven, meltblown, polypropylene material; and a third ply formed of a non-woven, thermobond, polypropylene material. In the four-ply mask,there is an additional ply of non-woven, colored, spunbond, polypropylene material which may be of any color and acts as the face-contacting surface of the face mask.
