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
Using a tape level, measure your head just above the ears and across the forehead and then refer to the size chart below. Check the fit by moving the chin bar up and down. The helmet should fit snug enough to move the scalp up and down rather than the liner just slipping on the hair. Also be sure to pull up on the back of the helmet to make sure that the helmet cannot possibly be pulled off of your head.
