Above is material low inside is antibacterial layer. the inner layer is also material and not as papery as the 3ply surgical mask. The 2 ply can be washed 2 plus times - must be followed by ironing. (so if you do a good job you can get masked 3 to 5 times) If my info is correct there will soon be legislation for companies to provide washable masks to workers. So this is a good affordable start.
