Well, I can tell you that every helmet must undergo the same certification to become a certified helmet. This means that no helmet is safer than another. So pretty much the GPA's and Charles Owens are a fashion statement (that I admit, I am sucked into). I can tell you that i LOVE my charles owens, and believe that they are the most comfortable and classic looking helmet. The GPA's are nice too, but I dont like the sporting look (its good for jumpers). Anyway, I believe that these helmets are expensive because they can be, and people will buy them.
I love Alexis, Bindi and Maggie!
