Mick, just had a proper look at the suit - the whole suit is 'as new' I'd say.
The seams are all solid and double glued and taped neatly on the inside.
The neck and wrist seals are thin neoprene and as new.
The integrated socks are rubber as not perished etc. There is 1 small neoprene patch glued to the rubber boot, it started to peel on one side, I'd gently pull it off and glue on a patch from a bike repair kit.
The zip needs some wax on it, but is fine.
The suit has neat low profile wear pads on the knees, arse and elbows which I hadn't noticed before and a large bellows pocket on the leg for tools etc.
All in all its a really decent suit.
I'd wrap it up and post it for £10 extra.
