Good point, Kelly - My CO was the best fitting helmet, which is why I bought it, end of story :)
Or.. as it was told to me, it can take more minor falls/drops, I.e. You don't have to replace it if you drop it from a reasonable height.
That's what was said when I bought mine, as far as I can remember, almost 3 years ago now...
I will do some research and get back to this thread tomorrow :)
