In reply to deepsoup: I think it was a Mtn Equipment jacket on here the other day that was also described as giving "incomparable" levels of protection to other jackets. It looked a very nice jacket, but that still seemed a bit of a claim!
Of course logic suggests that if all other helmets give, lets say, 8x to 10x levels of protection, if one model gave "incomparable" levels of protection to all other helmets, it could be that's because it gives 1x levels; although I'm sure that's not what Metolius's UK chaps want to be suggesting here!
More seriously, it looks a good helmet although I it's a bit heavier than the average these days. Although knowing you have
some more protection may well compensate for the extra weight.
