A soft, flat-and-round-topped hat with a small visor. Similar to military field caps, it is generally green in color with a red star ornament. Originally called "liberation cap" (解放帽 jiě fàng mào) in China because of its long time service in People's Liberation Army as the standard uniform cap.
Called the Mao cap in the West for being Chinese communist revolutionary Mao Zedong's signature cap, as well as previously being used in stereotypes of Chinese clothing.
