''Mongkol is the Thai word, which used for describe something with a good bless or prosperous.
In Muay Thai, Mongkol refers to a circlet that boxers wear on their fore head which they believe Mongkol will safe them and keep them free from danger. In the past, Mongkol was used as a formal outfit that boxers have to wear at all time during the fight, and never take it off until the fight is finished.
However, at present time Mongkol is only some kind of amulets rather than the formal outfit and boxers do not have to wear Mongkol throughout the fight. They just wear Mongkol just before the fight, during Wai Kru Ram Muay ritual dance and take it off when fight begins. The tradition of wearing Mongkol in Muay Thai was from the ancient times when soldiers use holy frontlet wear on their forehead before go to the battle.’
