Giant vents in the front and better protection for the back of your head, who woulda thunk? it fits very nice and fastens to your head comfortably with the exception to where the strap connects with the helmet in the back. it doesn't attach directly to the helmet, it ties through a looped strap that is connected to the helmet, as a result you can feel a little bump on the top of your head. I know it's picky, but I shelled out a lot of money for this lid. other than that, the helmet vents well, it looks good, and offers better protection for mountain riders.
