      Sleeping bag 5 star. Stuff sac 1 star.

      This is a comfortable and warm sleeping bag for car camping or even hanging out in the living room. I like that you can separate the two sides and use them as separate blankets. The sleeping bag is hefty, but it will definitely keep you warm.

      My only issue is the stuff sac that is provided. It is a workout trying to get the sleeping bag back in. I know they have videos showing it can be done but it is also done by employees or people who camp often. I relate it to someone who’s never shot a basketball before struggling to make a basket and a basketball player coming along saying it’s easy. All you have to do is this. The stuff sac seems too small for the size of the sleeping bag. After an hour and a half or so of trying I finally got it back in but it took many tries, a few calls to customer service for help, and a lot of sweat. From my understanding there is a larger stuff sac available for purchase but I don’t see why I it didn’t come with it in the first place considering a ton of people are having trouble with the current one.

      In the end, don’t let the 3 star discourage you from getting this sleeping bag. I still recommend it for couples, those with kids, or those who want extra space. I just have to take into consideration the default system as a whole and the default stuff sac isn’t that good.

      Thank you for taking the time to leave such a detailed review! It's great to hear that you're enjoying the comfort and warmth of the sleeping bag. We designed the stuff sack with space-saving in mind. However, we recognize that it may not be the perfect fit for everyone, so offer a larger stuff sack. Your feedback is incredibly valuable to us, and we appreciate you sharing your experience.

      "Mammoth"-true story

      Got this for Christmas 2023.

      We have a King sz bed in mt cabin,this thing hangs to the floor,its weight is super light, its warmth is A+,it has not caused us to sweat as the cabin warmed up--(except when I tried to get it back in the bag that it came in);p crazy but true! it is soft & billowy.Our bed is coveted by the other family members & friends that have seen it! :p Geeesh!!! We bought another one when they went on sale so my husband has one when he goes hunting or fishing to use for sleeping in the back of the truck or boat.

      Shows no sign of pilling or coming apart.No problems .Love it!

      Great bag

      It’s a Teton sleeping bag, which pretty much covers the topics of quality and HAPPINESS with the product. The ONLY thing I don’t like is that you cannot roll this bag up and put it back in the sack. I just feel there should be some sort of strapping on it so it can be made to fit while rolled up. Besides that, it’s an amazing bag with lots of room. I’m 6’4” 270lbs and the wife is 5’9” (don’t dare mention a weight but not fat lol) and this bag is more than enough for well into the 0 thru -5 temps.

      Perfect name

      I placed an order for 5 of the regular bags and then 2 of the mammoths. I figured the kids could share the mammoth if they wanted to and have it as a backup. When the first one arrived I could not believe the actual size and comfort of the Mammoth. I could not get it away from the kids for the first few days. My three boys actually took it to one of their rooms. I am not sure if I will get it back.... Very well made and comfortable to sleep with.

      Giant Comfortable Sleeping Bag

      If you need a big sleeping bag, this is the one to buy. I bought this for myself, my wife and our 85lb chocolate lab to share and it works perfectly. The quality seems great so far and it is very warm.

      A little note concerning the reviews about getting this behemoth back into the bag, I found the trick that works for me. Don't try and roll the sleeping bag first and then put it into the bag. I fold the sleeping bag in half and start shoving it into the bag from one end and it will fit into the bag. It takes a little bit of persuasion, but it's worked every time for me.

      Can’t Say Enough!

      It feels so good to crawl into this bag at the end of a long, cold day. I’ve shared it with a partner and I’ve used it solo in temps between 15F and 40F and it is so comfortable and cozy. It is bulky and heavy and I’m obviously not taking it on the trail, but it is perfect for my car. The liner is so soft and feels good on bare skin-yes-you can sleep in it with minimal dress if you want and you’ll still stay warm. I love this thing and am very happy I have it. I did get a zip up protective duvet for it because 1. the shell is kinda loud when you move around and the duvet helps dampen the noise, and 2. it will only fit in large industrial washers at a laundromat-and probably have to be in 2 pieces so I want to keep it as clean as possible.

      Warm & thick!

      This bag is the first sleeping bag we have used where I didn't get cold. It is perfectly puffy and cozy. I know others have mentioned they are unable to re-stuff it but after watching the YouTube video on how to, we've had no issues stuffing it away. The Mammoth is cloud-like...we love it. Excellent customer service as well.
