Abstract
A Go-go-kwan is a particular hat which has worn by married woman in Mongol and Yuan dynasty in China. It is also widely called as a Boktak in Mongol. The Go-go-kwan, recorded in jip-sa and in the miniature painting of 14th century is the early type of go-go-kwan. Later type can be seen from the relic collections of Gyeonggi Provincial Museum in Korea. The Go-go-kwan is composed with three parts ; feather part, tube part and hat part. Among the feathers, the largest one is as long as four times of the length of the tube and the shortest one is half the length of the tube. The tube is made of light weight wood such as white birch or bamboo, and covered with silk. Some of the hats were made exactly to fit on the head whereas others were designed to wear on the head as like jobawi.
