How to measure your height:

1 Head circumference

Measure your head circumference by placing the tape measure horizontally around your head. Guide it about one centimetre above your eyebrows across your forehead and around the widest part at the back of your head. Make sure the tape stays at the same height all the way around and is neither slipping nor too tight so you get an accurate measurement.

Casco hjc c91n

Il casco è di buona qualità, è stabile buona aerodinamica, abbastanza silenzioso a 130 km/h. Scomodo il comando visiera solare sopra il casco, meglio quelli di lato.
