Wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small.
Comment: I love this helmet!! The fit is perfect & I usually have a hard time since I am right in the middle btwn XS & S. The small is snug enough without being too constrictive. Made well & looks sharp!

Good Choice HJC CS5N Helmets
