The damage is to the polystryene lining inside the shell of the helmet. The only way to assess this is with an X-ray of the hat.
it's a Shark RSF3 if that makes any difference??? you can see the poly lining when i remove the inner padding and looks ok?
dammit, i guess replace is the safest option :-/[/quote]

No its where the polystryene meets the glass fibre shell that takes the hit. Impossible to see.

It's your head and your choice at the end of the day. But there are some very good hats out there for very little cash.
