Kaupinam, kaupina or langot is an undergarment worn by Indian men as a loincloth or underclothing, usually by pehalwan exercising or sparring in dangal at traditional wrestling akharas. It is made up of a rectangular strip of cotton cloth used to cover the genitals with the help of the strings connected to the four ends of the cloth for binding it around the waist of the wearer. It is used by wrestlers in the game of Kushti or traditional Indian wrestling in the akhada (wrestling ring) and during practice sessions and training.
