A shemagh, also known as a keffiyeh, is a traditional Middle Eastern headdress typically worn by men. It is a large, square scarf made of cotton or wool, usually folded and wrapped around the head and neck for protection from the sun, dust, and sand.
There are many different ways to wear a shemagh, but the most common method is to fold it in half diagonally to form a triangle, then wrap it around the head and neck, leaving one end hanging down over the shoulder. The other end can be tucked into the waistband or left to hang loose.
