Measure your head using a sewing tape measure for the most accurate result. If you don't have a sewing tape measure use a piece of string and then measure it flat against a ruler or builders tape measure. The Below measurements are taken from inside our hats so match these as close as possible to your head measurements.
All our hats have a size adjustable sweatband so there is a 2cm tolerance for each size.
