found a Lewis waterproof pvc/nylon over-suit in my wardrobe today, and if it has been worn three times, I'd be surprised.
In great condition with ankle zips/velcro fastenings and velcro cuffs, it looks like it would fit a rider who is 5'10 - 6'01, and the chest looks around 38-42.
It folds into an attached bum-bag with a belt.
If any subscriber wants it, I'll post it to mainland Britain in the price - a bargain £20 all-in via bank transfer. PM me if interested.
