1064 Fahrenheit TETON Sports Mammoth +20F Sleeping Bag

A truly HUGE family camping bag, the Mammoth easily fits couples and even a kid or pet. Its nearly as big as a queen size bed, with zippers on both sides to get in and out without waking up 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 +20F 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 around everybodys necks 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 can be flipped over head and ears. Even includes a massive stuff sack with compression straps. If you stuff rather than roll, we promise the bag will fit.

  • Enormous bag five feet wide and nearly eight feet long
  • Top and bottom separate completely with left, right, and bottom zippers
  • Connects to an unlimited number of Mammoth bags for a huge sleeping space

Q: How are you supposed to clean this sleeping bag without using a washing machine?
Asked by: Luke - 11/3/2016
A: TETON Sports recommends the bathtub method which is similar to the steps in our “Washing Your Backpack” post, located here. It’s a bit challenging, but it is a better option than your machine for protecting your warranty.
1. Fill a bathtub with warm water and add some mild detergent—but only a little bit.
2. Agitate by hand. Your hand agitation coupled with the soap will clean the sleeping bag.
3. Rinse well.
4. Dry. Hang it up in an open area, preferably outside in the sun.
Another recommendation is using an essential oil like lemon mixed with water in a spray bottle or use a commercial deodorizer. A clothesline comes in very handy here. Simply open the bag fully, lay it length-wise on the clothes line, spray your bag with the desired deodorizer or sanitizer, and let it air dry in the sun.
