ok so last weekend i got a good concussion and after hitting my head as hard as i did, my helmet, a smith holt, is now rendered useless, so i need to know what some good helmets are. The fit of my holt was ok but it didnt quite work for my head. I tried on a red hifi and they fit my head decently well so something along those lines would be good. Im pretty much open to anything tho so just tell when would be good.
