How to measure your head for the right helmet size
Get a measuring tape marked in centimeters. This is important, since centimeters are a smaller unit and will produce a more accurate measuring result. Have a pencil and paper ready to record your measuring.

Take the measurement around the circumference of your head at the widest point above the eyebrow bone, over the bump at the rear of your head and just above the top of your ears. Use a mirror as an aid, if unsure whether you are measuring correctly.

Check your measurement with the helmet size chart above and select the nearest size. If you can't find a helmet size that exactly fits your head measurement choose a helment size just smaller to your head measurement.

Important:Your helmet fit is not only critical to the comfort and enjoyment of your helmet, it also plays a critical role in the performance of your helmet in the event of a collision. Never purchase or wear a helmet without ensuring a snug fit.
