A truly HUGE family camping bag, the Fahrenheit Mammoth easily fits couples and even a child or pet. It’s nearly as big as a queen size bed, with zippers on both sides to get in and out without disturbing your partner. A third zipper on bottom means you can separate the bag into two quilted blankets. Use the side zippers to connect an unlimited number of Mammoth bags. The Fahrenheit Mammoth sleeping bag is made with the same construction and materials as the highly-rated TETON Sports Celsius series sleeping bags, and the 100% cotton flannel liner adds luxurious comfort to the elite bag. It contains 8.5 pounds of SuperLoft Elite 4-channel hollow fiber insulation with double-layer offset stitching. Shoulder baffle cinches in to prevent drafts. Full-length side zipper baffles and Velcro tabs at the top of zippers keep zippers in place and cold air out. Drawstring mummy-style hood. Even includes a massive stuff sack with compression straps. If you stuff rather than roll, we promise the bag will fit.
