Gat (hat)
A gat is a type of Korean traditional hat worn by men along with hanbok during the Joseon period. It is made from horsehair with a bamboo frame and is partly transparent black in color.
Most gat are cylindrical in shape with a wide brim on a bamboo frame. Before the late 19th century, only noble class men could wear gat, which represented their social status and protected their topknots.
Under the Joseon period, black gat were restricted to men who had passed the gwageo examination. Commoners wore a variant called paeraengi which was woven from split bamboo.
Artisans who make gat are called ganniljang in Korean, from gannil + jang.
