To ensure proper sizing, please do the following:

AGV Helmet Sizing:

Measure your head size. Pass a tape measure horizontally around your head at a height of about one inch (2.5cm) above your eyebrows.  This will measure the largest portion of your head.

Select the helmet that is closest to your head size.  Often times your head measurement may fall between two helmet sizes.  When this occurs you should first try on the smaller size.

Helmet should have a snug fit around your head yet remain comfortable for long riding periods.

 

Note: Sizing charts should be used only as a guide.
