Helmet Sizing Chart
Take a head measurement with a cloth tape measure. Wrap tape measure around your head one inch above your eyebrows, directly above your ears and to the widest area at the back of your head. Make sure the tape measure is tight and it is best to make the measurement in front of a mirror.
