Smoking caps, otherwise known as thinking caps and lounging caps, are caps worn by men while smoking to stop their hair from smelling of smoke. They are also worn to keep the head warm. They were popular in 19th-century England and usually used by gentlemen in the privacy of their home. They are often worn with a smoking jacket. They are probably of Chinese, Arabic, or Turkish origin. They are similar to the fez, and the kufi.
