I fell this year in a G10 helmet. I believe that the adjustable plastic thing in the back was driven into my trapezius muscle during the fall and acted as a fulcrum against which my cervical spine was bent.
Give me a break.
I am thinking of going back to a full-head Boeri helmet purchased in 1998. It fits the head snugly and perfectly, and though it has old styrofoam, it looks like it would be OK.
You know, I've bashed my head in that helmet on numerous occasions on Whiteface ice... no pain.
EVERY time I've fallen on my head in a G10, I've had pain lasting up to 6 months.
I think some of the new era of helmets are actually cheap pieces of sh*t, mass produced to supply the ubiquitous demand and thus turn over massive profits.
That is all. Next time I ski I'm breaking out the 1998 Boeri helmet.
