Nice mask. It’s comfortable and provides good coverage - I have a big head, and chose the large-size mask. I’d prefer it if the elastic straps were adjustable: The upper one is OK for me, but the lower is a little bit loose. The one real problem I have is my glasses fogging. The mask is thick, and when I put my glasses outside it, they’re too far out. Inside, and they fog. No problem for folks who don’t wear specs.
It is hard to breathe. However it is comfortable and large enough to cover my lower face.
