Helmet replacement

[Irulan]

I"d replace it, why even question it? I bet if you look hard enough you'll find cracks it in. It sounds like the emts were called in due to the nature of your wreck, and you would have second thoughts?

From what I understand, having broken more than my share of helmets, is that they are designed for one major impact. The foam will fracture in a microcrystalline manner before the cracks ever show. Other kinds of helmets, like rock climbing and kayaking, have foam that is designed to take multiple hits, but not bike helmets.
