Years ago, the Gander Mountain outlet center had 4XL and 5XL hunting bibs on clearance. I bought a couple, sewed the legs shut and together and made like a huge oversuit with an enclosed foot area. Super warm for those sub-zero days. Those have since gone away, now I get a cheaper sleeping bag and sew suspenders on at the top. I store them in a plastic tote by my stand so I don't have to carry them back and forth each time.
