This Realtree camo mask is made with double layer fabric and has a probiotic finish for protection and prevent skin irritation. It is made to cup over the nose, mouth, and chin for full coverage and has a flexible wire sewn into the bridge of the nose for a better fit. The straps have a miniature toggle that moves to adjust to a comfortable fit. One size fits most. These masks are for general non-medical purposes only.
