We recommend measuring your head to determine helmet size. Instructions below for the Mini Lifer, Lifer and Mega Lifer.
How to measure your head
Use a tape measure or phone charging cord and ruler to determine the circumference of your head then use the reference guide to determine what size helmet fits perfectly.

Also good to replace if your head has grown or shrunk or maybe you've changed your hairstyle.
