The Better Fitting Helmet!
Helmet Sizing Info

We ask that you use the following information to hlep choose the proper size helmet. In order for a helmet to protect properly and be the most comfortable, it must be sized to your head correctly.

To find the correct size helmet for a persons's head:

  1. Measure the head circumference one-inch above the eyebrows and ears.
  2. Using the circumference measured, use the chart to find the approximate size.
  3. Have the person try the helmet on and see if it feels snug equallly around the head. The helmet should not feel too tight or too loose at any point around the head.
Please remember that all head shapes vary slightly and that this sizing chart is to be used as a starting guide, not and exact guide.
