Weight I unfortunately do not know. In almost all my jackets I have "Heavy cotton drill" as lining. Both body and sleeves. I like it the best so far. My new jacket, hopefully coming soon, will get wool tartan and satin sleeves for a change.Here’s another naive question: what weight of cotton would you choose for a lining? I think I’d like a selvedge due to it’s potential balance of breathability and robustness, but of course the range is vast, from gossamer shirtings to some of the ridiculous denims that IH et al indulge in. FYI, this is for a summer jacket, probably mid weight horsehide.
