That's cool and all but where's their report on WaveCel?

@WAKIdesigns: I have to say as a engineering student studying helmets and concussions in cycling, your comment is pretty interesting to me. I'm curious why lab testing is not a credible source for you? Think about a bike crash that could result in a concussion. To simplify think of the crash in 2D. There is an x and y component to the linear force, a friction factor between the helmet and dirt, as well as friction between your scalp and the liner of the helmet. Additionally, there is the rotational force as you make contact with the ground. These forces can be figured out with a couple calculations and you could retest with different rider weights and speeds. As far as I can tell, you could easily replicate these conditions in a lab and I don't see why you couldn't get a very good picture as to how well a helmet will perform in real world conditions. I'd love to hear your reason. To me, the virginia tech helmet ratings seem quite well done and I would encourage you to look into their research https://www.helmet.beam.vt.edu/bicycle-helmet-ratings.html

@owlie: He's fine,I used to play lacrosse with that kid.If I remember right he walked away with only a concussion
