I had a flip up helmet and loved it. After my accident though I will never own one again. My face had it the bumper of the truck (I'm assuming) but it shattered the whole front of the helmet off and the only protection that was left was the sides and top. On the flip up style usually the sides only go to the middle or a bit farther on the cheeks. If I had not stopped with the truck and slid down the road there was nothing protecting my face anymore. After seeing my helmet and the little hit it took I just cant wear one again.
