The triangular pattern of the fabric covers the face from the cheek bones down as such covering the nose, mouth, cheeks and chin as well as the neck.

On the same principle as a t-shirt is better than bare skin, a fabric face mask can take a little bit of sting out of glancing and long range shots.
