Head measurement
up to 57 cm
up to 58.5 cm
XL up to 61 cm
XXL up to 63.5 cm

Practical advice: to take the measurement, you must place yourself in the strongest part of your head. The latter is located in the middle of the forehead, generally 1 cm above the eyebrows, where the hat will rest. Take the measurement with your head straight and the tape horizontal.
