Review on 👍 Efficiency Comfort Folding Disposable - Optimal Comfort and Convenience by Viterbo Dashora

I took them on a trip knowing I would need to wear a mask on the flight. It doesn't heat up my face and keeps it warm for hours. The structure allows for good blood circulation so you don't feel out of breath. I was in a city that did a lot of running and climbing and I was able to keep this mask on without getting out of breath. Holds up well, doesn't slip. It fits both my face (kid size) and my friend's face (medium to large adult size).
