How to measure yourself for a HELMET.
Measure the circumference of your head by positioning a
tape measure in the middle of your forehead, wrapping it around
above your ears and around the back of your head.
If you have longer or shorter hair, there may be some tolerance
either way. So if you prefer a tight fit, go for a smaller size and
if you prefer a loose fit, go for the bigger size. If you are uncertain,
always go for the tighter size.
If the brand of helmet you require is not listed below then please use the *Guide Size measurements to choose the correct size for you
