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.
