Saudi men and boys, whatever their job or social status, wear the traditional dress called a thobe or thawb, which has been called the "Wahhabi national dress".[46] During warm and hot weather, Saudi men and boys wear white thobes. During the cool weather, wool thobes in dark colors are not uncommon. At special times, men often wear a bisht or mishlah over the thobe. These are long white, brown or black cloaks trimmed in gold. A man's headdress consists of three things: the tagia, a small white cap that keeps the gutra from slipping off the head; the gutra itself, which is a large square of cloth; and the igal, a doubled black cord that holds the gutra in place. Not wearing an igal is considered a sign of piety. The gutra is usually made of cotton and traditionally is either all white or a red and white checked. The gutra is worn folded into a triangle and centred on the head.
