      Super warm!!

      We absolutely love this bag. It kept us so warm up in the mountains in Utah. The sleeping bag fit back in the bag the first time trying. All we did was stuff it in without folding it at all. Great purchase and so happy with it. All we missed out on was the Sale price of $50 less!

      I used the sleeping bag in 30 temperatures and it was very warm. The problem I had was putting it in the storage bag. It may be impossible the storage bag needs to be bigger

      Good bag, will not fit in it's case

      Overall we enjoy the sleeping bag, however, once the bag is outside of it's case (which is quite a struggle to remove in the first place) it will never, and I mean NEVER go back inside, so be prepared to forever have an oversized sleeping bag taking up way too much space somewhere in your home or garage. I recommend buying a tote to put it in, as the case that comes with it is far too small. Also plan on getting creative when it comes to compressing and maintaining compression when attempting to stow it, as some sort of straps, rope, etc will be required. Otherwise it will just immediately fill with air and resume it's jumbo size. Sleeping in it is great though. If space is not an issue, I recommend.

      Sleeping bag

      The sleeping bag is magnificent - the shipper (FDX) is not. Give the purchaser the choice of using FEDEX or UPS.

      FedEx is terrible is this part of Michigan

      HIGHLY Recommend

      The 2 person Teton Sports Mammoth Sleeping Bag is so comfortable! Its spacious enough for both me & my 1O month old Male 1OO+ lbs Rottweiler to sleep in & still have room to turn over, its nice that while laying on the Mammoth Sleeping Bag that its got enough layers that not only keep you warm but enough that it cushions your body from the hard ground. The mummy hood on the sleeping bag is a nice handy feature to the sleeping bag, especially during the Fall or Winter season when its raining like your in the Amazon. 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 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!

      A fabulous bag. Can easily fit two adults or an adult and two children. We took it out of the sack and let if fluff up with air for a few hours and then returned it to the sack. We did this just to see what all the fuss was about concerning the difficulties people have returning the sleeping bag to it's sack. Re-packing our bag took about 55 seconds. Don't let the negative comments concerning this issue dissuade you from buying this sleeping bag. It's perfect for car camping. You'd never consider this for backpacking but that's not what it's designed for anyway. It's massive. They have videos on YouTube that go over all aspects of the item.

      Thanks Teton!
