Common kid really? You are riding a 12 right? We had zero equipment as youngsters and now as adults even with the very best equipment DO NOT PANIC. Bro, that's like rule number 1. Keep calm and ........I wouldn't buy a helmet from any where but a store. New and in box. One drop and that helmet will be no good to you if you ever really need it. Can't trust it. And that's something your life could depend on too. I wouldn't gamble on it.
