Welcome to our GMAX Snowmobile helmet sizing chart. This chart indicates how you measure for helmet fit and how you determine the size that fits you. You should note that the GMAX sizing chart is based on averages, it works for most people.
First, you measure for helmet fit. Wrap a measuring tape around your head just above your eyebrows. Be sure to pull the tape comfortably snug. Take several measurements, to make sure you have the largest one. This is your circumference.
Second, determine the GMAX helmet size that is right for you:
