      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

      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!

      Great sleeping bag very confortable and fluffy . but it's impossible to put in its bag when it is out. A larger bag will be ' great plus.

      This bag is super warm, I live full time in a poorly insulated. RV traveling the country. Have been trying to figure out what the extra hook and loop closure are supposed to be used for. I get that part of it let's you have a bit more room around the shoulders. There are extra bits I'm not able to figure out and it's not shown on the website. Help please?

      Super comfortable bag and plenty of room for a tall guy like me. The only downside is the stuff sack is too tight, it takes a small army to pack this up.

      The sleeping bag is great. Warm and comfortable. But the carrying case is too small. It was a mammoth effort even just getting out in the first place. There's no way we can get it back in. Maybe that's why it's called Mammoth?

      I LOVE this sleeping bag. It is super comfortable, very soft, and so roomy! I was thinking about getting this as a gift for my other family members, and after my experience the decision is clear!

      This sleeping bag is so warm and comfortable! It's also very large so there is plenty of room for me and my husband, and even our baby when she wants to cuddle with us. Highly recommend!
