Head shape can play a factor in helmet fit. So our size guide is meant as a starting point and will work for most people, there are exceptions of course. Rounder heads will usually fit based on measurements, but if you have a more oval head shape, you might be better suited to a larger size.
If your head circumference is in between sizes, it is advisable to go up a size.
Helmets use the same shell sizes with different sized inner shells. For example, it is possible to change a medium size to a large size by replacing the cheek pads and liner. Please contact us if you would like more information on sizing.
How to measure your head
Using a flexible tape measure, measure the circumference of the widest part of your head, above the ears.
Please refer to your actual measurement and do not rely on your existing helmet size.
