Do you think they will ever make a dirtbike helmet with the big cooling holes like a bicycle helmet has?..... I am pretty susceptible to high heat riding conditions (I hate them).... Luckily we have had a cool summer this year, but the biggest problem with the high heat for me seems to be that my head just gets too warm.... to the point of almost causing nausea.... It would seem that if you took the MX helmet design.... added all the big holes from the bicycle design.... and maybe increased the overall thickness of the "inside to outside dimension to recover some of the strength that you would lose from having all the holes that maybe it would help..... safetywise I think only a real pointy rock in just the right spot would penetrate to the skull(have you ever hit your head on a real pointy rock?).... I know that one of the biggest hurdles would be the threat of lawsuits claiming the helmet wasn't adequate protection.... which would prevent a manufacturer from producing one..... But if somebody made one would you buy it?... Do you think it would help?.... I know another solution is just to get in better shape so the body cools itself better.... but besides that what do you think?
