It consists of an upper band that is tied around the forehead, together with a long wide piece of fabric which covers the face, leaving an opening for the eyes. Many full niqab have two or more sheer layers attached to the upper band, which can be worn flipped down to cover the eyes or left over the top of the head. While a person looking at a woman wearing a niqab with an eyeveil would not be able to see her eyes, the woman wearing the niqab would be able to see out through the thin fabric.
