There is a 3rd layer of lining with a pocket, to add a disposable filtering material\fabric. To wear, simply place the mask with the higher end over your nose and tie the nylon spandex tie behind your neck. Straps are similar to swimwear ties. To untie, pull one end of the tie, keeping in mind not to touch the face mask itself with your hands. Hand wash for best results. At this time Face Masks are available in yellow only on line. Note for custom quantity orders of 36 units or more we can print your one color logo on the right or left side of the mask.
