buy ls2 carbon helmet. they sell for 150 or something in ebay. plus u get warranty if u crash they replace free of charge :)
I've bought it and don't even own a motorbike
It's been around this price for a while. Have a look at this thread from 2014: http://www.bikechatforums.com/viewtopic.php?t=279695
Don't need buy REALLY want. .....
