"It looks like a very substantial mask. I haven't used it yet. The extra layer should be much more protective. It looks like the Medline ones that I had to wear during the Flu season when I brought my Therapy Dog to visit St. Joseph's Medical Center's Nursing Home in Yonkers. They were far more substantial masks than the 3 layer ones that everyone sells. The only difference is that theirs folded in half." - Francine W.
