NOPE, I use undies, and a couple more layers of undies if needed, up to including 2 smart Wools, then wool shirts, heavy socks, wool outerwear, heavy boots and if need be boot blankets. Then of course there are always chemical heat packs and all the frills. I'm a big enough bundle and then add all the clothes, well there's no room for a sleeping bag. LOL I wouldn't worry about the legs as much as I'd worry about the trunk if I were you.
