But... some helmets have a cage system in them. As you go up the line you will also see improvements in fitting technology which will play a significant role in impact protection. As well as lightweight, venting, and cosmetics.

But just so we are perfectly clear.

All helmets offer the same type of CPSC (or whatever it is) crash protection. That is a standard that they all meet.

Higher end helmets DO offer better crash protection than their low end counterparts.
