The Helmet Update

We are often asked why there is no anti-concussion helmet on the market.
One major reason is the thickness of the energy management material required. So we asked two noted helmet experts to
estimate how thick a helmet made of today's EPS foam would have to be to keep the g's below 100 in the CPSC impact test
that uses a two meter drop on the flat anvil. They prepared a paper detailing the various considerations.
The result: the helmet would be very thick. We have a new page up
with the research and the mushroom helmet
that you may find amusing:
There are other materials, of course, but helmets made of them are similar in thickness to EPS helmets. And there are no
published test results indicating that there would be a major difference in thickness.
