First and most important, they fit great. I grew my full beard back after twenty years being respirator qualified. These masks have a foam nose piece. It provides a great seal to prevent fogging my glasses. The full size gets under my chin. I get a much better seal than the KN95s we've been using. Shipping took a while, but we also had Winter Storm Uri in the middle of all this.
And, they're made in America!
