The best way to make sure the helmet will fit you is to measure your head. This is also the case for kids as age is not a good indicator. 

This is the best way to do this:

  • Have a flexible tape measure and place it around the circumference of your head.
  • Position the tape measure at the middle of your forehead, 2 fingers above your ears and at the widest point at the back of your head.
  • Note the result and then browse our amazing helmet range! Be aware that sizing varies from model to model.
