Masks are made with two layers of 100% cotton, pleated so they are able to extend over nose and mouth. They include a metal strip at the top so they are moldable to your face for extra protection. Masks also have nylon elastic for optimal comfort - so soft and stretchy they won't hurt your ears or leave any marks even after wearing for a long time.
