Abstract

A field mask for protecting the face and head is disclosed. The mask includes a top portion, side portions, and a face portion. The face portion of the mask is flared outwardly at its lower end so that the wearer may lower his head without the lower end of the mask's face portion making contact with his throat. The mask is formed to permit the wearer to wear eye glasses and includes filter vents and a removable transparent lens.
