Arai Helmets - Size Chart
To obtain your helmet size, measure the circumference of the head, one inch above the eyebrows and above the ears. Much like a head band would fit. Take this measurement a few times to ensure accuracy. Compare measurement to chart. If measurement is between sizes, choose the next larger size. Helmet should fit snug, but not overly tight.
