Outlaw T-72 'Knight Rider' Black Synthetic Leather Dual-Visor Motorcycle Half Helmet - Small

My head circumference is 21 inches and the small was too big. My husband is a medium in harley Davidson helmets (I am an extra small) and it fit him alright. Very nice helmet though. Sad to send it back.

Fits good...looks good.But since I got a full face for my camera and headset...no longer use.Looking cool doesn't give protection.
