The mongkol (also called mongkon) is a type of sacred headpiece worn by most Muay Thai boxers before fighting. They wear it to the ring and while they perform the wai kru ram muay ceremonial. Their trainer then takes it off their head and place it on the top of their corner for good luck. It is a symbol that represents your loyalty and respect of your gym, your trainers and your family. Literally speaking, mongkol means holy spirit, luck and protection.
