Best thing to do is get someone that knows what they are talking about fit your head to the helmet. Headliner and cheek pads need to be sized to your anatomy. Usually at the motorcycle show you can get Bruce Porter from Arai to measure your head and fit you to the proper size. He will give you some great information regardless of the brand you decide to buy. As far as my choice I like Arai because it fit my head shape the best. I also have tested it and know for a fact it saved my life.
