100% Recommend, Buy It !!!
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 5â7 and my partner is 5â5, 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 itâs 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.

WARM
WARM! The temperatures listed in the specs are probably spot on. Our first trip it got down into the 40’s and we were both roasting. Don’t worry about rolling it back up like it is shipped, you can stuff it in the sack and the outcome is the same.

Gigante pero cumple su función.
El producto en sà es fantástico, lo use un par de noches con 2 grados dentro de la carpa y no necesite más abrigo. No le puse 5 estrellas porque es IMPOSIBLE volver a colocarlo en el bolso en el que viene. Claro, de fabrica lo embalan con una maquina, pero los que lo compramos no tenemos esa maquina asà que al cerralo uso zunchos para que quede doblado.

Very warm
My wife and I took this product on our epic 5,000-mile honeymoon road trip, and it truly blew us away! We faced multiple nights with temperatures dropping well below freezing, but we stayed warm and cozy all night long. This product didnât just performâit exceeded every expectation we had. Even after such intense conditions, it held up flawlessly, and we still rely on it for all our outdoor adventures. If youâre looking for a game-changer that guarantees comfort in the harshest conditions, this is it. Itâs become an essential part of our gear, and we wouldnât hit the road without it!

Uh, yes, Mammoth is a good name for it lol
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.

Very nice
Amazing and separates into 2 bags

Excellent!
Amazing for winter camping! It fits us both and our two 50-lb dogs. I love that the zippers allow you to air it out and keep using it as the weather gets warmer.

Es muy cómoda para dos personas, y te mantiene caliente, no se pasan la sensación de humedad del suelo (pasto), asi que uno duerme muy cómodo. Si lo usas en casa, para visitas yo compre un colchón inflable para amortiguar lo plano del suelo, la primera noche la use solita y me quede con dolor de cadera

Teton sleeping bag quality is perfect
Colin Fitzgerald –
Incredible quality and workmanship, the material is so soft and durable at the same time. The zippers are durable and they look like they will last for years to come. I love how you are able to open the bag on either side as well and this fits perfectly over our Coleman queen sized air mattress.I think the coldest we have slept in this bag outside so far is in Banff National Park when it was about 5 or 6 degrees at night after a whole day of rain.The tent was like an icicle but this sleeping bag was like a furnace.The bag is so easy to put away as well, just fold the sleeping bag in half and stuff it into the compression sack. I was amazed at how such a huge thing could be stored in such a small bag.2021 edit:Still working perfectly. Have been using this sleeping bag with my other half for 3 years and it’s still like brand new. Have spent much colder nights since my first review and we have 0 complaints. One trip in Yoho last Fall it went down to about -4C and this thing kept us toasty warm.Before we go on any camping trip, I take the bag out and let it sit in the sun for a few hours. I then turn it inside out and do this again. I was told by Teton that unless your bag is heavily soiled this is the best and easiest way to clean your bag. This seems to do the trick as every time I do this the bag smells like brand new.I highly recommend this sleeping bag as I have recommended it to all my family and friends.

Best ever

Primero que nada PARA GUARDAR EL SLEEPING DE VUELTA EN SU BOLSA sólo basta meterlo hecho bola, uno tiende a pensar que hay que enrollarlo y luego meter el rollo en la bolsa del sleeping, pero resulta que no es asÃ, basta con meter una orilla del sleeping y seguir metiendo el resto del sleeping asà hecho bola en la bolsa, sin tener que enrollarlo ni nada, nada más lo metes como puedas y asà es el chiste con los sleepings, no tiene ciencia, nada más comenzar por un extremo y seguir metiéndolo sin ningún orden ni técnica. Pueden ver tutoriales si en youtube buscan “How to Stuff the Mammoth Sleeping Bag into its Stuff Sack”.Ahora sà el review:El sleeping está perfecto, perfecto, es súper resistente, muy acolchadito y extremadamente calientito. Yo nunca habÃa visto un sleeping tan grande como este, tan grande y pesado. Pero lo cierto es que es sumamente calientito. Incluso podrÃa decir que está de más de calientito, yo casi no paso frÃo pero mi novia sÃ, asà que lo compré esperando que estuviera cómoda mientras acampábamos en el Parque Nacional del Chico, en Hidalgo. Por la noche la temperatura estuvo como a 6 grados y ella estaba sùper cómoda pero yo estaba incluso sudando, de hecho el material sintético del que está relleno hace que la humedad se vaya al piso, dos noches el sleeping amaneció mojado de mi lado, dado que no se derramó ningún lÃquido creo que mi mismo sudor se fué al piso, haciendo que mi lado quedara mojado, eso sà nunca me habÃa pasado en otro sleeping, realmente amaneció mojado. Creo que eso puede ser una ventaja, en lugar de que el sudor humedezca la parte interna se vá al fondo del sleeping que amanece mojado.Creo que el sleeping está un poco sobrado para las temperaturas en México, pero es un hecho que si lo compran no pasarán ningún tipo de frÃo, está perfecto si lo que buscan es el sleeping más calientito que puedan encontrar.Sin embargo el sleeping es grande, encontré que las medidas son exactamente las de un colchón de tamaño matrimonial, queda exactamente sobre la superficie del colchón, si necesitan darse una idea es exactamente asÃ, lo que mide un colchón matrimonial, ese es el tamaño del sleeping extendido, perfecto para una pareja; el sleeping ya empacado es un cilindro que mide algo asà como 80 x 50 cm ya comprimido y es muy pesado, no tengo báscula a la mano pero debe estar cerca de los 8kg. Es enorme y sólo lo recomendarÃa si vas a viajar en coche, porque irlo cargando no es opción.Sà lo recomiendo, a mà se me hizo de más de calientito, pero eso te asegura que soportarás temperaturas de hasta unos -5 grados centÃgrados, fácil.
