Determining correct helmet size
Your helmet should fit snug and securely around the entire circumference of your head. Cheek pads should be firm against your cheek bones and offer support from the helmet moving laterally. We offer multiple shell options, cheek pads and liners for a custom fit and superior comfort. Please reference the following guide to get started.
- Use a soft tape measure to get your correct head circumference measurement. Measure horizontally around your head at a height about one inch above your eyebrows and 1/2 inch above each ear. This should give you the correct largest measurement for reference to the size chart below.
- Cross check the sizing chart to determine your proper size helmet.
- Select the helmet size that is the closet match to your head measurement. If your head size falls between two helmet sizes you should try on the smaller one first. Often times helmet pads and liners can be swapped to customize fit.
Checking for Proper Fit
With the helmet on, go through the following to determine whether you have chosen the correct size. Make sure your head is seated all the way into the helmet and contacts the comfort liner on the crown of your head as well as the entire circumference.
The cheek pads should be firm against your cheek bone area. With the chinstrap securely fastened, grasp the helmet firmly with both hands. Without moving your head, try and move the helmet up and down and side to side. You should feel the skin of your head and face being pulled over and about your skull as you try to move the helmet.
If you can move the helmet around easily without this sensation the helmet is too big and you will need a smaller size. Next, try to rotate the helmet forward around your ears. It should not be possible to remove the helmet in this fashion with the chinstraps properly fastened. If you cannot adjust and fit your helmet as described above, DO NOT USE THE HELMET as serious injury or death could result. Replace the helmet with the correct size.
