These disposable face masks by LYMASK are highly breathable. My husband and I, agree that they fit really well. They have a great nose piece that does not irritate my nose. My favorite feature is the color. Purple! I wear this shield every day in really hot temps at work. I use a fresh one half way through the day to feel fresh but if I don't change it, I still feel protected. It fits perfectly and does not stretch out. I highly recommend this mask.
