'Mongkhol'

What is a Mongkol? 

The Mongkol headband worn by Muay Thai fighters during their pre-fight Wai kru dance is something audiences see so often. But do they know the hidden meaning of this storied accessory? For the fighters, the Mongkol is a talisman that supposedly brings prosperity to its wearer. It is usually made from holy thread or raw fibers that have been consecrated by Muay Thai masters before being wrapped and bound into a band that is worn around the head, with a long tail hanging down the back.
