I have a half helmet that is DOT approved. We have strict helmet laws in TN, so i am TRYING to stray from buying a novelty helmet. The DOT helmets get caught up in wind so they arent comfortable and the novelty are more comfortable and look awesome. BUT they arent legal So i thought about taking the fabric out and getting rid of some of the foam. Have considered using a dremel, melt it or sand paper. Anybody have any experience with this?
