My head is 59.5 and the large is perfect. It is a squeeze to get on and off but once on perfect. Very comfortable. Vents are great, goggles dont fog up.

Had a ls2 adventure helmet before this, but couldn't get on with the visor on it. Brought this to use with Google's and has space for intercom ear speakers so it's a win for me.

LS2's Fast II helmet is a technically advanced weapon for serious off road riders. The shell is made from LS2's proprietary Kinetic Polymer Alloy (KPA). This innovative material is ultra-lightweight and offers a bit of energy absorbing flexibility, but with a penetration resistance that rivals high-end composites. The wide eye port accommodates most major brands of goggles. Intake and exhaust ports ensure plenty of ventilation to keep you cool, whether during a long moto, an enduro, or a long day on the trail.
