how much you sweat in them
how much you actually use it (not just length of years owned)
ozone (like exhaust fumes, and really any chemical fumes)
extreme heat and extreme cold
and yes..........the quality of the materials used in production
all come into play, but all the helmet manufacturers suggest 5 years is the outer limit.... but I do find it very arbitrary given so many variables......
personally I have never worn any helmet more than 2 seasons, sure I have bought plenty of brand new 2,3 even 4 year old helmets on closeout..... knowing I won't wear it but 1-2 years
woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!
