Review title is No more fog [SEP] Wearing a mask doesn't ordinarily bother me, but it does fog up my glasses. This is the perfect solution for that problem. This are made very different from all the other mask brackets I've tried. They are made from a soft but thick polymer material that makes them bend and stretch. They are perfectly portable and can be carried in your pocket easily. They are really lightweight and cant even be felt when you're wearing them. They keep the mask up off your nose and mouth therefore keeping you from breathing heavy and hot air and causing glasses fog. Great value !
