A great deal of effort has been put into making GMAX
Helmets-The Better Fitting North American helmet. We ask that you use
the following information to help 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 person's head:
1. Measure the head circumferance one-inch above the eyebrows and ears.
2. Using the circumferance measured, use the chart below to find the
approximate size.
3. Have the person try the helmet to see if it feels snug equally 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 an exact guide, to begin fitment of a helmet. |
