When you want to cuddle while you camp, choose the TETON Sports Mammoth Sleeping Bag. It will give you the best night's sleep with shoulder and zipper draft tubes, drawstrings at the shoulder and around the head, and dual-layer construction with offset stitching to eliminate cold spots. The Mammoth is filled with SuperLoft Elite four-channel hollow fiber insulation—all these features work together to keep you warm and comfortable anywhere you set up camp. If you get too warm, just unzip the bag a little at either corner or down the side. The bag comes apart in two massive quilts for ventilation or you can zip multiple Mammoth bags together for an even BIGGER sleeping bag. Comes with a free compression sack. Here's a storage tip: Stuff the bag in, don't try to roll it up and then put it back in the sack.
Color: Blue Taffeta | Temperature Rating Degrees: 20 Degrees Fahrenheit

- Assuming you have someone in the bag with you, DO NOT LAYER UP too much. We were in t-shirts and shorts and we were VERY warm in the Colorado mountains where it was in the low 40s. We even unzipped the sides to put a leg out at one point! Bottom line is that unless you're literally in below-30 temps, you probably don't need to stack up the layers. A base layer, something on your ears/head, and some warm socks is probably all you'll need if the temps start to drop.
- Outer layer is sturdy and soft.
- Inner lining is VERY soft and cozy. I expected something a bit less comfortable if I'm being honest so it was a very pleasant surprise to find such a lush inner lining.
- Zippers are great! While we didn't separate it entirely, I did notice that both sides zipped independently and each had a lined velcro strap to cover the zippers so the cold metal won't touch your skin. I was hot one morning and was able to unzip my side while my wife stayed bundled up. Speaking of which, there is also a cinch around the top of the bag to create a mummy-style enclosure as seen in the picture. That little cubbie is also good for stuff pillows to keep them in place.
- Lots of straps on the stuff sack; easily carried like a backpack if need be!
- Get ready for a workout if you're using the stuff sack it came with. Unless you have a magic folding/rolling gift, you'll probably want an extra set of hands to get the first quarter of the bag in the sack. After that it's just a matter of stuffing all the way down to the bottom of the sack...which takes some effort and time. We are able to get first half of the bag in the stuff sack pretty easily after a few practice runs but fully utilizing the full volume of the bag is difficult. I have found, however, that after cinching the bag closed, the bag molds itself to take up the entire sack so it all works out in the end. If you want an easier time, you'll probably have to buy a bigger stuff sack but...
- The stuff sack is already pretty big and heavy. It has plenty of straps for carrying/tying down but it definitely isn't suitable for more than a very light hike if any.
That about covers my thoughts. If anything glaring comes about, I'll update but this is a fantastic double sleeping bag, especially for those of you who like snuggling up.
I bought the 20 degree two years ago, and have used it in the backwoods of Wisconsin, waking up several times with frost on the bag. My wife and I have amble room, (Me: 5’10” 175lbs. Wife: 5’3” 115lbs). Larger folks could easily be comfortable in this bag.
Several weeks ago I bought the 0 degree bag to use on a North Lake Tahoe car camping trip. (The 20 degree bag was on backorder and I couldn’t wait). Temperatures were in the low 40s, high 30s, and we were both very comfortable.
I haven’t been able to compare the 20 degree bag, and the 0 degree bag side-by-side, since they’re in two different locations, but I’d just buy the 0 degree bag in the future. If you’re too warm, the zippers work great, so it’s easy to let heat out. And since sleeping bag temperature ratings are based more on survival temps, not comfort temps, the 0 degree gives you a wider usage range.
Two minor things I don’t like: the drawstrings up around the head. I don’t see myself ever using them, and they can get in the way. The other is the stuff sack, I wish it was a bigger. It can be a workout to get the sleeping bag back in the sack. As mentioned, these bags are big and bulky, and having a stuff sack that was 6” longer would be nice. I’ll probably just buy an extra large duffle bag in the future to store the bags.
Tip: For people that tend to be especially cold sleepers, toss a couple of those HotHands style hand warmers in the sleeping bag about an hour before bedtime. They’ll definitely help keep you warm, and toasty throughout the night.
The downside: It's big-really big. I'm used to a mummy bag in a compression sack and this is about 6 times the size of that. Also, it will never fit back into the sack the way it came and you should just stuff it to keep your sanity. If you are backpack hiking this is not the sleeping bag for you. If you like to be comfy and you car camp like I do, you'll love it!
( TIP= I used a nylon X-Large laundry bag I had lying around and folded it into that 1st....just to get the decompression process started and then I put it in the carry case - Not sure if that was easier or not...but its the only way I was able to maneuver it!!!) Soooo....Heads up...if u purchase this bag have a solution in mind to repack/transport it. I will update review again after field testing on our camping trip, but so far that is the only complaint.
********Okay, here is the update I promised (a little late). We used it camping and it was great!! It is still a pain to repack into the travel case and my "process" was less then ideal after a few days in the woods camping (it was a lot of effort, but it worked we got it back into the original casing). Still working on a solution for repacking the sleeping bag, but it functioned exceptionally (we were warm and dry the entire time, with room to spare!!!). *********
