Three years is about middle age. Most manufacturers recommend replacement after seven years, but that's a generalization. It depends how much you used it, how roughly you transported it and how much it was exposed to sun and heat. Fading color, delamination and distorted internal foam (not to mention cracks) indicate it's time for replacement. One rule: Always replace your helmet after a crash. (Some manufacturers even offer special replacement warranties on crashes.)
i know that rosebank offer a replacement , send the helmet back with $5 and a discription of that accident and they'll replace the helmet
