As Tibet has strong sunshine and change-able weather, as well as strong wind whipping up sand, Tibetan people like to wear a hat in different styles related to status, sex and region. The most common one is called "Xamo Gyaise" -the golden thread hat. The lining is made with a felt cap base. The top is decorated with golden silk and the edge is inlaid with silk ribbon. The hat is designed with four edges, with the front and back ones being larger and the left and right ones smaller, all sewed with furs. With fine materials, it is very warm and loved by both men and women. Worn by women, the two larger edges are placed inside the hat, leaving the left and right ones outside, and by men, the left, right and back ones are placed inside, leaving only the front one out. In snowy weather, the four edges are all placed outside. The elderly usually set the four edges outside. It is practical and cannot be compared with other hats.
