How do I determine my helmet size?
Use a measuring tape to measure the circumference of your head.
If you plan to wear an arming cap and/or coif under your helmet, put these on first. This is important for determining your helmet size.
Measure around your head, over your eyebrows and around your ears. Ensure that you measure in as straight a line as possible.
Note your size and compare it with the size chart in the helmet description.
