...on a semi-related note, when is the time to get a new helmet? Do you only get a new one when you've cracked it through?
It's my understanding that you should replace any
helmet that's taken a "Significant" impact! Although, I'm not really
sure what constitutes "Significant!".
Can't help wondering myself just how hard an impact is necessary to compromise the protection afforded by a helmet? I've fallen a few times and "popped" my noggin against the hard pack hard enough to give me a moderate headache afterwards, (...even a little mild whiplash type pain in the neck once or twice!) ...but nothing
sever enough to cause seeing stars or losing consciousness afterward.
I would be interested in knowing myself just what level/type severity of impact would be enough before you seriously consider replacing a helmet?
