Adult Helmets Size Guide
Helmets should feel snug and secure, without pressure points. Measure your head circumference and match it to the size below. If you sit between sizes, size up - you can always fine tune using the helmet adjusters.

How to measure
Wrap a tape measure around the widest part of your head, sitting just above the eyebrows and around the back of the skull. Keep it snug but not tight.
- No tape measure? Use a piece of string, mark the length, then measure it against a ruler.
