GMAX Snowmobile Helmet Sizing Charts
Welcome to our GMAX snowmobile helmet sizing chart page. These GMAX snow helmet sizing charts are also featured on each product page.
Remember that sizing charts are based on averages. They work 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: |
