I've purchased 3 of these sleeping bags and we all LOVE them! High quality, plush and I bought them not just for camping out but also because you never know when you might need them during a power outage in the winter to stay nice and TOASTY indoors!!!!! Great to have on hand for recreation or necessity! : )

If you’re flying to camp this is pretty big to get in some suitcases. But it’s worth it for cooler temperatures. We also used it for warm temperatures too and it wasn’t too bad.

A late fall camping trip on the north shore of Lake Superior is a chilly experience. The 0°F Mammoth Dbl Sleeping Bag was exactly what my partner and I needed to keep warm for a few nights. The extra baffles at the zippers and head opening keep the cold out. We highly recommend this to future chilly campers!
- MKMelissa K K.Verified ReviewerReviewingFahrenheit 0˚F Mammoth Double Sleeping BagI recommend this productRated 4 starsNov 8, 2022Honestly The Best Sleeping Bag I've Bought Yet
The 2 person Teton Sports Mammoth Sleeping Bag is so comfortable! Its spacious enough for both me & my 1O month old Male Rottweiler thats over 1OO+ lbs to sleep in & STILL have room to turn over & whatnot. It's nice while laying on the Mammoth Sleeping Bag that its got enough layers to it that it not only keep you warm but it has enough layers that it cushions your body from the hard ground.
The mummy hood on the sleeping bag is a very handy feature to the sleeping bag.
Not only does it help keep your head warm, heat inside the sleeping bag but it somewhat helps keeping your pillow in place.
This Sleeping bag is best used during the Fall or Winter season when its raining like your in the Amazon or up in the mountains during the spring . The bag being waterproof leaving you dry or when its snowing as if your in the East Arctic Circle still keeping you warm even if its -O degrees outside!!
I highly recommend this sleeping bag to quite literally everyone, for Family outings, going hiking with or without your dog or if you have come upon hard times and are houseless. This sleeping bag is well worth it!

Not only was this sleeping bag roomie but very comfortable! It kept me warm throughout the whole night. Very happy with this purchase and would recommend it to anyone who was looking for a comfortable warm sleeping bag. The only thing was it was a little tough getting it back in the bag it came with.
- BRBrian R.Verified BuyerReviewingFahrenheit 0˚F Mammoth Double Sleeping BagI recommend this productRated 5 starsOct 16, 2022Amazing!
This bag is incredibly comfortable and very warm. The temperature on our recent camping trip dipped down into the 30’s (Fahrenheit) and we stayed toasty. My wife usually runs cold and hasn’t found a bag that actually keeps her warm…until now. Looking forward to more winter camping adventures now.

Just returned from camping above 10,000 feet in the San Juan Mountains. We wanted to stay warm and this bag is fantastic. So cozy, so roomy, so warm. The challenge is to convince yourself to leave it in the morning. We love it. But this thing is HUGE! No way we could get it back into compression bag. It wouldn't fit in any of our totes. So we bought a 50x60 sea bag to store it in. It takes up a lot of room in our jeep. Zipping it apart and putting it in two bags like suggested above is a great idea (not sure why we didn't think of that.) Anyway, we love this bag and now must plan more cold weather camping to do before our camping days are over (we are almost 70).
