TO ENSURE AN ACCURATE FIT, use this chart to order your correct helmet size. Carefully measure around your head, above the ears. Take the measurement, in inches or centimeters, referring to the sizing chart above for your correct hat/helmet size. Helmet must fit properly for optimum performance. Don't guess your size. Helmet must be securely and snugly fastened before engaging in any activity.

To obtain the best possible protection, a helmet must fit properly, be positioned correctly on the head, and be securely fastened. The first step in the sizing process is to measure the circumference of the head by using a cloth tape (or a string). Take the measurement about one inch (2.54cm) above the eyebrows in the front and at a point in the back that results in the largest possible measurement.

Due to variations in head shape, heads that measure the same may not necessarily fit the same helmet size.
