Don't get me started ! I have spent a few hours in the last few days and in fact just got done searching again. I generally wear a 1/2 or 3/4. But i'm looking to replace it with a chopper/fighter style helmet and a full face i'd use just for cold morning commutes. But i always have a very hard time with this because if i can't try them locally i can't buy. Buying online is horrible because i'll never get the right fit first time, and usually you have to pay shipping. So for example, i found a helmet i really want the other day but they only sell them online. So i pay $15 shipping and if it doesn't fit i pay another $15 back. Thats $30 just to try it. Then if i ask to exchange it for another size thats $45 i've paid in shipping. Lets not even talk about if the helmet just doesn't fit my head shape and i have to send that one back too ! And the problem for me is that almost every chopper/fighter pilot style helmet is not available anywhere near me locally except the AVG dragon which doesn't work for me. So in order to get the helmet i want i would have to buy online and likely pay several hundred dollars in shipping fees to buy a $60-100 helmet. That said, i think i give up. I'll stick with the barely satisfactory Z1r i have now and see if i can find a cheap full face for cold weather locally. that one i don't much care about other than it's warmer for those rarecold morning commutes maybe 20 times a year.
So i always end up buying locally. That is, unless thier prices are rediculous. then i will try it on locally but buy online. not nice, i know. But to be honest i don't give a F.
