Bests & Worsts Reviews from Amazon

I am really happy with this item. It fits well and comfortably against my face, and fits well under my masks. The biggest advantage is that it keeps the mask off my nose & mouth, which allows me to breathe much better and keeps me from feeling claustrophobic. I was frequently out of breathe when wearing masks before, and think these will improve that substantially, especially as a teacher about to go back to the classroom.
