ABSTRACT:
A disposable face mask includes a mask body covering substantially a nose, mouth, and chin of a wearer, and an extension provided with the mask body. The extension is configured to encircle a back of a wearer's head and to substantially cover a wearer's cheeks, jaw, and ears. A substantial portion of the extension is formed from a resilient material treated with a repellant agent to prevent contaminants from entering or exiting such treated portion of the extension.
