1. MEASURE YOUR HEAD. Determine the circumference of the widest part of your head by using a flexible tape measure. Generally, the widest part of a person's head is the area 2.5 cm (1") above the eyes and ears. However,
we suggest measuring at a few points both above and below that line to determine the greatest measurement before referring to our size tables. We also suggest testing the fit of a helmet one size smaller and one size larger then what the chart recommends.
No helmet can provide protection if it's too uncomfortable to wear.
If you would like further detailed instructions on how to determine your correct size please look at our AFX Helmet Fitting Guide.

AFX90 Dare Helmet Reviews
Comment: I purchased 2 of these helmets in June, they are really nice helmets for the price, the fir was great and comfortable.
The only concern I had was the size chart, my head measured 21 1/2" and the chart said I should get a x-small helmet which I knew was nor right. I knew my hat size was 7 1/2 so I went by that instead and ordered a large helmet, so I think the hat size is more accurate then the inch chart. All in all great helmet
