Head shape can play a factor in helmet fit. So our size guide is designed a starting point and will work for most people.
If your head measurement falls in between sizes, it's advisable to go down a size. 
 Please contact us if you'd like more information on sizing. 
We offer a free (UK only) returns service if your helmet doesn't fit.
Head Measurement

 

How To Measure Your Head

Using a flexible tape, measure around the circumference of the widest part of the head, above the ears. 

Please refer to your actual measurement and don't rely on your existing helmet size.
