We have 2 available nice sleeping bags, though there are potentially recent cold germs on them. =/ Or I have a different old one that doesn't look pretty and is a little heavy and noisy but is water-repellent and hasn't been exposed to anything for years. =) Of the first two, there's one thinner (3lb) and one thicker (4lb), the thicker is rated to -5°F, the other should be just above zero, I think. The older one should be good into the 40s, at least.
