Hi everyone. I have a hard time finding a decent helmet for my five year old. Last february I bought him a AGV helmet and it is huge, he got his neck collar few months later and the two don't fit very well together. I didn't think of it when I bought the helmet but it is an XS and it comes in one shell size only. When he has the chest protector and his collar, it almost looks as they push the helmet upwards, looks almost a little funny, but certanly not comfortable, and maybe not safe. It looks to me as most of the kids helmets are at most 52cm, but they did't fit, and just a few days ago I measured his head to be little over 53 cm. I will upgrade his helmet this winter as he will make the transaction form an ATV to a (hopefully) KTM pro junior. If you have had the same problem or if you have any ideas, any input would mean a lot. Merry christmas and a happy new year. Jóhann.
