I think I currently have 18 sleeping bags, and five of them weigh 17.5 pounds each. One weighs a little over 22 pounds. So planning for the SHTF Today I ordered two more of the "TETON" -35 degree XXL Outfitter Sleeping Bags. This should give me several hundred pounds of total weight of all sleeping bags. "The TETON Sports Outfitter XXL -35ºF/-37ºC is a large and comfortable sleeping bag. At 92 inches long and 39 inches wide, this spacious sleeping bag is longer than a twin mattress and only 1 inch narrower. The zipper baffle and padded drawstring opening keeps drafts out. This bag's staggered seams distribute fill evenly and reduce compression to eliminate chilly spots. It has cotton flannel lining for ultimate comfort. It comes with no-snag, self-repairing zippers which open top or bottom for adjustable ventilation and connects easily to a second bag for shared sleeping space. This is the best extreme weather rectangular bag you’ll find."
