I work in a medical center & wear a mask all day. Masks are currently required in public in my city too, so I've tried a number of masks of different designs. This mask is thoughtfully designed like no other that I've seen nor used. The flaps across the top & bottom provide a lot of coverage, and the top flap, with a metal strip sewn inside, is a huge help with steaming glasses. The velcro straps make it easy to put on and adjust for a comfortable fit. This is the best mask I've found.
