Sizing your helmet.
Giro's unique In Form™
adjustable fit system allows a wide range of fit per each size. You are able to dial in your comfort level with a built in adjustable headband. This
comes in especially handy when you need a little extra room when wearing a head liner. To get the correct helmet size, measure the circumference of your head just above the eyebrows with a soft tape measure. When in doubt, go up
one size.
SMALL, between 52 - 55.5 cm or 20.5 - 21.75 inches
MEDIUM, between 55.5 - 59 cm or 21.75 - 23 inches
LARGE, between 59 - 62.5 cm or 23 - 24.25 inches
