In reply to Damo:
Cheers for all the tips and advice folks, appreciate it. Damo, I'm pretty sure they are a size large, no markings on them, and they are the old olive green ones. Also, if I fail, as I'm duel nationality, do I get to keep one passport?!
Ice solo, I know wellies for the woods, but I don't possess such a thing and thought I'd make use of my old Mantas and yeti's because I was bored!
I think they do actually still have them for issue in certain places although I'm sure you wouldn't need them in this day and age, unless of course you're heading off into deepest darkest Hampshire forests!
