Hmm, you feel just a single-lining of 16oz. moleskin would be a bit much? I figured the total ~30oz. weight would be comparable to a heavy melton peacoat I have.I have used silk in the past, but frankly, it didn't do much in terms of added warmth. Maybe a lighter-weight (10-11oz.) flannel?Typically, I would just ask my tailor, but my new tailors in HK doesn't have much experience with this sort of thing and have asked me to guide them.
