HOW TO MEASURE YOUR HEAD
Use a flexible tape measure or a non stretchy string: Place the string or tape around your head about 1/8" above your ear, across the mid-forehead, completely circling the largest part of your head. Hold the tape firmly, but not too tightly. Basically you need to measure your head exactly where the hat will sit. If you used a string: After you have marked the exact circumference of your head lie the string down on a flat surface and measure the length next to a ruler. Please measure 2 or 3 times to make sure you did it correctly or get a buddy to help you. It is most accurate to measure in centimeters. If your measurement falls between sizes, choose the next largest size.
