    • Good quality but a pain to get back in the bag
Color: Grey (Cotton Flannel Liner) Size: Mammoth 0F
Kept us warm but I wish the bag it came in was bigger or that the sleeping bag had straps to wrap around once rolled. It's a pain in the ass to get it in the bag, I found it easier to stuff if I unzipped the sleeping bag

    • 100% Recommend, Buy It !!!
Color: Grey (Cotton Flannel Liner) Size: Mammoth 0F
Review Image by Mike Gonzalez Mike Gonzalez
I am 100 percent satisfied with my sleeping bag, exactly what I was looking for. I have purchased other sleeping bags but they were cheap. This sleeping bag was very thick and also contained Cotton flannel liner on the inside which makes a huge difference when sleeping during really cold temperatures. I am 5’7 and my partner is 5’5, we both were able to sleep in this bag together with a whole lot of room left, we could have probably fit our medium size dog with us if we had brought her. I recommend this sleeping bag, you will not be disappointed. Now there is only one issue, do not try and roll up the sleeping bag to try and put it back in it’s duffle bag, you will struggle and it will take forever. I read one of the other reviews and the best way to get it in is by putting it in little by little to fill in all the bottom space of the bag, keep packing it in and step on it if you have to, is is wayyyy fast than trying to fold or roll it back in. ... show more

    • Con: It’s HUGE. Pro: It’s Huge.

Okay let’s start with the only Con being it’s HUGE. The only reason this is a con for me is because it’s impossible to get this thing back into its bag. That’s the only reason I’m knocking off one star. Hopefully this company can see the many complaints from customers about this issue and can provider a bigger bag in the future, for better storage. Now for the Pros: -This thing is HUGE and SO comfortable! It kept us warm the whole night, at times even a bit too warm. We seriously didn’t need any blankets at all, just this giant monstrosity!! Honestly this thing would easily be a 5 star sleeping bag if only we could store it away a lot easier. Nevertheless, I highly recommend anyone who is a serious camper (especially for those who camp in cold weather) to buy this. You need it! The price is a bit steep but so worth not being cold at night!! ... show more

    • Uh, yes, Mammoth is a good name for it lol
Color: Green Size: Mammoth 0F
I ordered the green Teton 0F Mammoth bag and this thing great, it is massive, super thick and cozy. Honestly the bag in the photos seemed smaller to me for some reason, I have never seen a sleeping bag this large in person. Did I mention this bag is massive. Its huge, ginormous, prehistorical in size... its a behemoth! Our ancestors might have chased it with spears to harvest its stuffing. So much fluff! And were talking the good kind of fluff here... If I were to describe it would be like the thickness of the fluff is 6-10 college type Queen comforters covered in ripstop zippered together. Getting it out and putting it back in the stuff sack is one hell of a challenge, almost like one of those carnival games where if you can best the unbeatable game you get a massive stuffed prize. I feel like a few more inches added to the stuff sack would make this more appealing and not a cruel joke for some people lol. For example when fully in the stuff sack the compression straps almost literally do nothing, thats how tight of a fit it is. Took about 6 minutes timed to get it back in. Just don't give up on getting it in or out of the stuff sack, or cut it off like the lady who reviewed before me lol. Do not take it out of the stuff sack in a place you do not want to store it or use it, even carrying it around out of the stuff-sack is cumbersome lol. I do feel like this gear addition is one of those multi "pro" and multi "con" type scenarios for car camping situations where interior space is a concern. I have a mid size car-uv and its pushing it packing this thing in there with other desirable gear. IF you sleep in a truck bed topper or a situation and can just leave it un-sacked this would be the best thing ever. Do I prioritize sleep comfort in my tent over breathable space in my car while traveling? Absolutely, and I'm glad I did. Jokes aside I love it though. It is everything i wanted in an OVER-SIZED sleeping bag and more, a lot MORE. More than I bargained for but when is that really a bad thing? I think I will really enjoy not being wrapped up like a mummy or straight jacket will be a game changer to my forest comfort. Due to the shear thickness of each layer, zipping/unzipping this thing works better than any sleep bag I've ever used, very smooth, did not catch (yet). I have not tested the warmth yet but it has all the appearance of something that will definitely live up to the 0F selling point. I might even get too warm in it. I tend to sleep with my bags open and over me with my feet in the mummy bag so I love that i can unzip each sections if i want it act as a comforter. I've slept in 20F down bags with a few layers, including insulated snowboarding bib and emergency bivvy in 13F weather and been still got cold so a 0F bag was desired. Is this bag perfect for everyone or all situations, probably not due to its size and challenge to store but Its exactly what it says it is, and if you have the room for it, someone to re-sack it, and the need for a cold weather bag where you will feel cozy this is it. ... show more

    • We loved this! Super warm!
Color: Ivy Size: Mammoth 0F
We absolutely loved this thing. It is not compact at all if that’s what you are looking for. We stayed in Colorado at about 30-35 degrees and never once got cold. Me and my husband both wore shorts and a tshirt, and we were warm the entire time. No extra blankets or anything. It zips on both sides so no one feels trapped. Great quality, nice color for camping. ... show more

    • Great sleeping bag!
Color: Grey (Cotton Flannel Liner) Size: Mammoth 0F
Great sleeping bag! The size is great as I'm 6'5" and it is long enough to go over my head, the inside fabric is soft and I stayed very warm in below freezing temperatures. The only thing about it I don't like is trying to get it back in the bag.
