How to measure your head
Watch the video for a demonstration of how to properly measure and fit your helmet.
Use a soft fabric measuring tape marked in centimetres (cm).
Wrap the tape around the widest part of your head: about one inch above your eyebrows, just above the ear line and around the bump at the back of your head.
Once you have your measurement in centimetres, click here for the size chart to convert it to our standard helmet size.
If you have a rounder shaped head or find helmets feel tight on the sides, consider Round Fit sizing.
If possible, we recommend having a professional fitting with your local retailer.
