Getting the right fit for your head.

This chart is meant to be used as a guide only. Try the helmet first before buying it.
Measure the circumference of your head using a fabric ruler.  Place it approximately on inch (2.5cm) above the eyebrows and above the ears.
Example: If the measuring tape reads 23" (60cm), your helmet size would be falling in the LARGE category.
