I have recently seen a couple of references to Joe's Jeans being offered in a thermal fabric for winter. I just went over to their website to look. It's something called Fahrenheit. I can't say I'm in love with the styles but I like the idea of a fabric that is "lightweight ... with state-of-the-art insulation. Carefully engineered hollow-core fibers trap in air to provide exceptional warmth without the weight."

I wonder if anyone has seen or tried these IRL and if they're really like denim. I disposed of my old, warm Eddie Bauer flannel-lined snow shoveling jeans last year because I took too much grief from my family every time I appeared in them. But I would like some warm jeans.
