A protective mask system and a method of manufacturing a foam/fabric mask face shield having a three-dimensional geometry. The mask system has a lens frame and a compression-molded composite sheet, which is formed by multiple layers. The method includes the steps of forming a composite sheet from two or more layers, heating the composite sheet, and compression molding the composite sheet into the three-dimensional geometry of the face shield. The composite sheet can be formed by the lamination of two or more layers. The layers can be bonded together by a bonding agent, can be heat bonded, or can be laminated together by other means
