If your measurement is at the maximum for size SMALL or MEDIUM (54cm or 57cm) we recommend moving up to the next size. HOW DO I MEASURE MY HEAD? Use a cloth tape to measure the circumference of your head. Ideally the measurement should be taken approximately 1/2″ above your ear. If you are in between sizes, or wear a hood that would increase your circumference measurement, we recommend you select the next size up.
