Thanks, will add them to the serches.
Just won a cheap motorbike jacket on eBay.
I know the best policy for helmets is to try them on, but how much size difference is between the different makes. As I very much doubt I can find a store stocking cheap ones I find on the Internet. Just need anything for the moment, with the idea of upgrading helmet in a few months, haven't even got transport to get to many bike stores.
