When should you replace a helmet?
Helmets are designed to protect your head from an impact. From just one impact. If you fall, even if it doesn't seem like the helmet is damaged, you need to replace it: it could be weakened or cracked in invisible places... and thus no longer provide protection. You should also consider replacing your helmet if it has gotten old. After 5 years, certain materials start to age, especially if the helmet is stored in a cold and/or damp place.
