Though helmets have come a long way they still rely on EPS aka Styrofoam to deal with the energy of an impact and transferring it, or hopefully not to your noggin. Looks like a cali company has figured out a better way to handle some of it.

Interesting concept. I wonder how the performance varies as a function of temperature? I like the way the helmet can absorb some of the rotational forces with the dual layers. Sort of like your scalp without all the blood and skin.
So these helmets- at least off road types are available now. But they are over $700 a pop - I hope they do well enough to bring the price down. The tech is interesting and looks promising I'd like to see it keep on.
I love that chart, because it blows away all that hype how SNELL is better than ECE ;)
They did a small piece on these helmets during the last AMA Supercross race. Apparently a few of the riders are wearing 6D helmets. Very cool. [thumbsup]
