General Sizing information
If you are unsure about your size, compare your body measurements to the charts provided to determine the correct fit. These charts will give you a good idea of the size to order, but be sure to read special sizing information that may accompany an item description. Some merchandise dimensions may vary from the averages charted here.
Head Size
Wrap tape measure around your head about one inch (2.5cm) above your eyebrows. Try on the helmet by grasping both chin straps to pull the helmet completely onto your head, ensuring that the top of your head is in contact with the top of the helmet interior.
