The face masks are made from 4 layers. Two layers of new high quality cotton fabric and 2 layers of non woven polyester interfacing, with an option of adding a 5th layer of t-shirt fabric as a pocket where you can add additional layers if you desire.
They have a wire pocket over the nose and darts under the chin to give a tight fit. The wire is removable for washing.
A continuous tie holds it in place or 2 pieces of elastic secure it behind the head.
