The sweatband bow is found on the inside of men’s hats. Attached to the inside, back seam of the sweatband.
Easy for men to tell which is the back of the hat when putting it on quickly.
Rumor has it that the inside sweatband bow resembles skull and crossbones. Making it is a nod to past milliners who were stricken with mercury poisoning by prolonged exposure to mercury vapors during the felting process.
