Hats size

In order to know your hat size, it is necessary to determine the circumference of your head and this is very simple as detailed below: take a measuring tape and firmly but not very tight, surround your head with the tape. Start from your forehead at about ¾” over your eyebrows and go around about 1/8 ”above your ears and the furthest part of your head, then check your size match in the size chart.
