I'd give these 3 1/2 stars.  These long johns are warm.  To me though, they are only comfortable if they're the only thing I'm wearing, e.g. around the house.  My woman says they look funny, and I agree, the lines and skin tight fit make them a bit unappealing.  Wearing these under jeans, etc., is okay but I find my legs itch and the trouser snake gets constricted.
