These Deluxe masks are made with organic cotton jersey on the inside, a layer of plain cotton in the middle and our cotton prima eco-print on outside (assorted patterns and colors). They come in 2 sizes - Medium & Large. There is a wire at the top to push down on your nose and create a good fit. Back is elastic so no pressure on ears. These masks are just like out popular regular ones, except they are in dark colors and the elastic is wider, soft and satiny.
