On that first clip it looked as if the helmet was actually broken rather than just the strap giving in. At the sort of speeds involved you would think something that offers similar protection as a motorcycle helmet would be better suited. I use a sweet helmet which I think is the best money can buy for my kayaking and for my snowboarding, however I am not sure I would want to take a 90mph impact wearing it.

Recovering with no memory of the crash. I have seen first hand what head impacts at that sort of speeds can cause and I am convinced he is a very lucky man.
