Rob Mound House,  CA Profile Sinister Helmet I've had a number of the cheaper $150-200 helmets and none of them seemed to fit my oval head. I always had a lot of pressure on my forehead. The Arai Profile is a perfect fit, snug, yet very comfortable. Very high quality helmet, I would highly recommend.
