not sure, I read a lot of written comparrisons and found the venting was the biggest difference. I can say that it is amazing venting compared to the kbc and icons i have owned. And turning your head at speeds between 60 and 80 is amazing becuse the wind doesnt try to rip your head off. havent gone much faster than that with it. And it is very comfortable.
