Nice one, Geoffrey Firmin. I have the JCrew Bayswater peacoat. Bought it in NY in 2010. It's very hardy, I wear it regularly in winter. Mine has the thinsulate lining which adds virtually zero bulk and from what I understand, adds to its insulation properties. Have to admit, the buying process for me was more along the lines of, "I'm fucking cold. What's the warmest coat you have?"
