Simply use a measuring tape and place it around your head from the front of your head, above your ears, until the center of your forehead (following the picture).
(Place it according to where you want your hat to fit).
While checking the size, make sure measuring the tape is not too loose or too tight. Take into account the hat will get the shape of your head.
We highly recommand to oversize it a little bit.
Then according to your preference and personnal taste, determine your size.
