7. Cincinnati Bengals: The Bengals are only one of three teams to not have a logo on the side of their helmet, which only adds to the importance of the stripes. Along with the striped theme, this color duo of black and orange has a certain sharpness to it. All of Cincinnati's previous helmets were great, and the streak continued when they added "tigers skin" to their head gear in 2004. Love it or hate it, you have to admit the Bengals were 100% original when designing their fabulous helmet.
