Jeongjagwan

Jeongjagwan is a type of gwanmo (관모; 冠帽). It is a traditional men's hat in Hanfu and Hanbok. It was first seen in the Five Dynasties period at the latest. In the Song Dynasty, two notable Confucian scholars, Cheng Yi (程颐) and Cheng Hao (程灏), often wore this kind of hat, so they were also known as Cheng hats (程子冠). The system of Jeongjagwan is slightly modified following the barrel-shaped Dongpo hat of the Song Dynasty. It is mainly woven with horsetail hair, and it was a hat worn by men from the yangban, the upper class of the Joseon period. It was mostly worn at home as a daily headgear instead of a gat, a formal headgear. Jeongjagwan is made with horse hair.
