How to measure
Measure the circumference of your head with a tape measure, starting above the ear, circling completely around about half an inch above the eyebrows and across the fullest part of the back of the head. Measure several times for accuracy. If you fall between two sizes, choose the larger; the helmet should be as snug as possible without causing pain.
