HOW TO MEASURE

1. Helmets: 

Use the sizing chart above as a guideline in determining your helmet size. To measure correct helmet size, measure around the head, one in inch above the eyebrows and match inch measurement in chart. If between sizes, it is suggested to go with the smaller size. The interior padding of your helmet will loosen and form to the shape of your head the longer it is worn. A helmet that is loose when new will get even looser once broken in. The final sizing decision will be that of the customer.
