After five years of wearing KN-95 masks that I liked pretty well, I still got my ears bent and my glasses fogged in cold weather. I just accepted it as the way it is. What a complete revelation these masks are for comfort and good looks, too! I am actually looking forward to wearing this mask in the airports and on a jet to Colombia, because I know I'll forget I have it on. What a blessing. I wish I'd found you five years ago.
