  • Patent number: 5704063
    Abstract: An altenative face protector made of a covering body for covering at least a portion of a user's face below the eye area thereof, and attachments for attaching the covering body to a user. The face protector covers at least a portion of a user's face and it comprises a breathing vent skirt element. The breathing vent skirt element has a skirt edge, and is configured such that when the face protector is worn by the user, the breathing vent skirt element, from the tip of the nose of the user, projects outwardly and extends downwardly in such a manner that the breathing vent skirt element defines an outer wall of a nostril air pocket extending below the nostril area of the user's nose. The nostril air pocket has a lower nostril opening which is in air communication, at an upper end thereof, with the nostril area of the user's nose and, at the lower nostril opening, with the atmosphere.
