Your SIMBA helmet should fit like a baseball cap. The objective is to fit the helmet snugly to your head. If your measurement is at the maximum for size SMALL or MEDIUM (54cm or 57cm) we recommend moving up to the next size.

HOW DO I MEASURE MY HEAD?
Use a cloth tape to measure the circumference of your head.

Ideally the measurement should be taken approximately 1/2″ above your ear. If you are in between sizes, or wear a hood that would increase your circumference measurement, we recommend you select the next size up.
