GMAX HELMET SIZING CHART A great deal of effort has been put into making GMAX Helmets the better fitting North American helmet. Please 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.
The best way to check sizing is to put the helmet on and see that the helmet feels snug equally all around your head. The helmet should not feel too tight or too loose at any particular point around your head. Use the following chart to find the approximate size helmet for your head.
Please remember that all head shapes are slightly different and the sizing chart is to be used as a starting guide to fit the correct helmet size to your head. Measure the head circumference one inch above the eyebrows and ears, then use this chart to find your approximate size.
