    • Roomy, Warm, Comfy - and bulky (but good for car camping)
Color: Blue Size: Mammoth 20F
Lots of room, nice and warm, and very comfy interior! We bought this for a 4 day camping trip in November, and it worked great! My wife actually questioned why we hadn't bought a double sleeping bag sooner. It is big, so be aware, this isn't something you're going to backpack in - it is strictly for car camping. It has a nice compression bag that it comes in, but since we have a camping trailer, we put it into a large (108 qt) Plano tote; it fills the entire tote up. Warm enough that I had to sleep with it unzipped most of the night (we bought the +20 temp). I have no complaints, and I've been a camper my whole life. ... show more

    • THIS IS ONE AWESOME SLEEPING BAG. BUT....
Color: Blue Size: Mammoth 20F
I'm really glad with this purchase. It has mega room. It's very warm. Haven't tried it at 20 degree rating yet, I'm confident base on how it did on a few 30+ degree nights. The inside feels very cozy. Regarding the padded neck baffle, this is strictly for when using as single individual bags when separated from being a double. But it didn't seem bothersome at all to us using as a double, which is mainly why I bought it. So everything about this bag is absolutely great....BUT.... Unless your name is Bruce Banner and you're in your anger state, don't count on getting this thing back into it's storage bag easily. In fact, it's also pretty tough getting out initially too. But since I didn't buy it for how easy or not it is to roll back up into it's storage bag, I simply bought a larger draw-string duffel sack to put it in, and that did the trick, very easy with no hassle. I guess I could also unzip them, and store them as individual bags like the one I previously used for many years. ... show more

    • Soft, warm, fluffy- packing bag TOO SMALL
Color: Blue Size: Mammoth 20F
Review Image by Cristi McCoy
This bag came the day before a last-minute camping trip, so I did not have time to wash prior. I slept in it with my toddler and we both kept very warm with lows of 40 degrees. We slept on a Klymit insulated inflatable mat, so I can’t say it was the only thing that kept us warm because we were protected from the ground. I also threw a blanket over the top with a sheet for my dogs to snuggle into so their nails wouldn’t scratch or snag the bag. Pros: It came without any odor and fluffed up very quickly and was so cozy and warm and luxurious. I slept with bare feet and they stayed plenty warm. Cons: Just 1, but it’s significant- It took FOREVER to get the sleeping bag out of the carrying bag it was packed in. It was the hardest bag I’ve ever had to remove a sleeping bag from. I read the reviews where people said they were struggling with it and thought, well…maybe they’re being dramatic. They weren’t. It’s a shame because this sleeping bag would likely receive more 5 star reviews, but for my experience, they sadly lose a whole star simply because of the packing bag design, it’s terrible, and there was not the slightest hope I could ever stuff this sleeping bag back inside the packing bag. I did a practice run the night before to make sure I could do it and it was such a waste of time. I ended up just using the packing bag to stuff all our winter gear into and used the purple sheet in the picture to tie the sleeping bag up in by the 4 corners. That stupid looking ball rode passenger in an SUV and nearly touched the ceiling. I don’t even know where to look or what to buy to store the sleeping bag- it is a fat, large, super fluffy sleeping bag. If anyone has found something they like for it, I hope they’ll include it in their reviews. Was it worth it? For sure. I love the bag. Would be singing its praises were it possible to store it in the bag in came in. So now, on to find a solution so this sleeping bag can be my go-to for years to come. ... show more

    • Man vs Mammoth
Color: Blue Size: Mammoth 20F
So there I was excited to use my new Teton Mammoth sleeping back with my wife and daughter. We get the bag out, fluff it a little to let it reach it's maximum "fluff status" and add in the sleeping bag liner(which I'd give 4 stars, needs a way to anchor in at the bag so it doesn't get tangled). The three of us get in to test it out and see how roomy it is.. and might I say.. it's roomy! Granted I'm only 5'8" 165, my wife is only 5'3" 115 and my daughter is only 1 year old but we could fit baby number 2 when it comes and still be comfortable. When the fun is all had, I was mentally prepared to wrestle this sleeping for the next hour to get it back in the bag after reading several reviews stating how difficult it is to get back in. My wife is pregnant so she took care of the insert while I single handedly slew the Mammoth. I folded it in half hot dog style and flattened it to let out the air and kept all the corners together and then I started rolling the sleeping bag using my hands and knees keeping the air out as I rolled. I grabbed the stuff sack it came with and guess what???? It slid right in! 5 minutes... 5 minutes! I was blown away at how easy it was, and I did it myself... I wonder if some of these people on here have ever rolled a sleeping bag before? I wonder if they've even rolled their own socks, I'm sorry for those it took an hour and a half to get this back in the bag, I'm surprised you even found the campsite. The sleeping bag is great, it's comfy and we are excited to try it out this weekend in 32 degree weather. I'll update this if I find that the wild somehow changes the sleeping bag, or perhaps my intelligence. If you are looking for a relatively inexpensive sleeping bag to cuddle with your significant other while in the great outdoors, this a great purchase(car camping only, I would never attempt to backpack with this beast). Please, take a moment and come up with a game plan before attempting, perhaps practice rolling empty garbage bags if you must, it's not that hard. ... show more

    • Toasty for two people!
Color: Blue Size: Mammoth 20F
This sleeping bag was so wonderful for our roof top tent when we went over landing in 40 degree weather! It kept us warm and didn't need to wear extra layers. Looking forward to trying it out in even colder weather to see if it holds it claim to a 20 degree Fahrenheit rating.
