Great product , top quality , very comfortable ,
The masks are well made, but could use some design improvements. They are not cut particularly well to accommodate the face (especially narrow faces) and lack a metal component at the top to help shape it against your nose; almost a requirement if you wear glasses. Definitely among the better I’ve purchased, but not the best for a narrow face.
