This is a Chinese Nationalist Revolutionary Army (NRA) officer's side or garrison cap of the 1930-1940s. Its design is based on the United States military garrison caps of the period, seen in the shape and folds of the flaps, and is made from lightweight cotton cloth. Featured on the front is a handmade NRA cap badge of the nationalist Kuomintang party. This style of cap was worn during the summer months.
