Why the EPS of my helmet look like this
It hasn't taken any damage as far as I know (I used it to go to school so It wouldn't surprise me if some dickhead have played with it) The helmet is only 6 months old. Exterior is fine as well. I have washed the interior once but I didn't used other than mild water. Maybe I'm just paranoid but I don't want to risk it. It doesn't have any compression as far as I can see.
