Fly Racing Adult Helmet Size Chart

How to Measure: Wrap a soft measuring tape around the widest part of the head, approximately one inch above the eyebrows and across the largest portion at the back of the head. Keep the tape level and comfortably snug.

For helmets, a secure and properly snug fit should take priority over a looser fit preference. The interactive size finder should use head circumference as the primary sizing measurement and should not intentionally recommend an oversized helmet.
