I have a gunmetal grey Thermawrap Parka in size Large, which is really a size medium-large (since it's Japanese sized). Fits me perfectly at 185/5'10". It's in very good shape, the only thing "wrong" with it is that it's got some slight piling on the forearms near the hands where the elastic stretch is. Otherwise, great shape.
I'd be willing to part with it for $80 shipped. Let me know, I can send pictures too. Comes with original stuff sack.
