Size Chart

As with all personal safety devices, helmet fit is vitally important and can increase the risk of injury if not properly fit. Carefully measure the head approximately one inch above the eyebrows across a point at the back of the head that gives the largest measurement. Please remember: Helmets will "break in" with use. It is important that the helmet fits as tight as one can comfortably withstand to wear.

Please see the charts below for helmet fitting. If you do not know your hat size, please take a cloth tape measure and measure around the circumference of your head, just above your brow line.
