Celsius Mammoth 20F

Honestly any bad reviews about this bag are personal preference because the bag is amazing. I’ve had this thing for about five years now it has been a life saver in the ber months, literally woke up in three inches of snow and didn’t even know it because we were warm and toasty inside, just got back from a trip torrential sideways rain/wind storm and our tent seams failed but we were warm and dry inside the bag. Getting it back in the sack is a work out and this thing is big and heavy but that’s because it’s warm large and comfortable and worth every fight to get it back in and the storage it takes up worth it we never leave without it. My significant other and I are large and tall people 220/260 and 5-10/5-11 we fit and have plenty of space we through it on our blow up mattress it has a little pocket which I love I keep my glasses in it or AirPods or phone all kinds of thiss the top is extended so the pillows can lay on the bag itself which is great. I will keep and use it until it’s no longer thriving and surviving and then I’ll buy another one. Stop hmmmin’ and hawing’ this is the one babe.

UPDATED REVIEW: I used this bag for 14 days at the Sturgis Motorcycle Rally in the Black Hills of South Dakota. The night time temperatures ranged anywhere from the high 40's to the high 60's at night. I was quite comfortable in this bag while sleeping in just a pair of shorts. I never intended to use it in any colder weather, I just wanted a sleeping bag that would keep my warm without having to have layers of clothing on. It did it's job wonderfully for me. As for the stuff sack. I was using my US Navy seabag, but it was still a struggle to get it into that bag as well. I have since purchased two 60 liter dry bags (I motorcycle camp) and by separating the sleeping bag into each half, it fits easily into the two dry bags. It is also much easier to pack on the motorcycle and carry each bag, instead of one large bag. First impressions, this bag is huge. I order this sleeping bag for a couple of reasons. One, I wanted a sleeping bag that would keep me warm without having to wear several layers of clothing, socks, winter hat, and a scarf. The weather I camp in, the temperature averages mid 50's at night, and may dip down into the low 40's on rare occasions. I've only had the bag a few days, and have tried it out once. It's warm, and I can sleep just like I do when I sleep at home in bed, no extra clothing required. So I give it a thumbs up on that. Two, I wanted a bag I didn't feel mummified in. I don't like the feeling of being wrapped up and confined when I sleep, this bag has plenty of room. I tend to toss and turn a lot in my sleep, and I don't wake up all twisted up with a zipper poking me in the back in this bag. At 6 foot 2 inches tall, and 180 lbs, I have plenty of room in this bag to sleep comfortably with room to spare. I motorcycle camp, and I pull a small trailer behind my motorcycle, so the size and weight of the bag are not an issue, but this bag is not for someone trying to be an ultra light back packer. It is larger than I anticipated when I ordered it, even in the stuff sack, but it still works for me. I can deal with the size for the benefits of warmth and sleeping comfort. I give it a thumbs up on this also. I had read the reviews before ordering this, and the stuff sack could be a little larger. Yes, I can get it back into the stuff sack, but it's a workout. Not something I want to try and do every time I go camping. Definitely not something I want to struggle with if I have to pack up in rainy weather. I have opted to discard the stuff sack, and pack it in my sea bag from days in the Navy. It works better for me, but the stuff sack is not a deal breaker by any means, I didn't buy the sleeping bag for the stuff sack. Overall, I am very happy with my purchase of this sleeping bag. If you want a large sleeping bag, that will keep you warm, has a very comfortable and soft lining, this is a great sleeping bag.

We had a camping trip in the Rocky Mountain National Park coming up in the fall, temperatures were supposed to be in the low 30s, or even upper 20s. This was one the first bags we saw when looking around, and we just couldn't stop thinking about it! It looked so roomy, so comfy, so warm, and the idea of a double sleeping bag was very appealing, specially in cold weather. So we went for it! Well, since I'm writing this review, you can assume we not only survived, but it was a great choice! Here are our pros and cons from our experience in Colorado: PROS: 1. High quality: right when you take it out of the box you know it's a good product. The inside feels like flannel. Zippers and seams look strong! 2. Roomy: this thing is huge, I'm 6 feet tall, and both my wife and I could fit inside with plenty of room for another small person. 3. Comfy: I'm just going to say that there is a very thin line between sleeping in your bed and inside this sleeping bag, very very fluffy. The inside is similar to flannel, so it's not too cold when you get in. 4. Warm: I gotta say, before seeing this bag, my wife was skeptical we wouldn't be cold at night, but our nights were perfect, we couldn't wait to get to bed. We both slept with very light clothes and bare foot. Temperatures were in the low 30s every night. 5. Details: some details are worth mentioning... there are zippers all around, so if someone is too warm at night, you can open the sides to increase ventilation. There is a mummy hoodie that helps close down if you're still not warm enough. There are some velcros to prevent you touching the zippers or opening them accidentally. CONS: There are no cons!!! I would say there is actually one side effect to so many pros... 1. Size: well, as you'd expect, it's very bulky and heavy! But hey, how would it not be, right? Some reviews talk about being difficult to put it back in the stuffing bag, but we did not have a problem at all! Fold in the middle, stuff it all the way to the end, and then stuff stuff stuff the rest! It really (to our surprise) wasn't as bad as we thought. Bottom line is, amazing bag!! You won't be disappointed. Just don't expect to go hiking a 10 mile trail with it! :)

Teton sleeping bag quality is perfect

Der Schlafsack scheint sehr warm und hochwertig. Überdurchschnittliches Plastikgefühl, aber OK & gehört für extremeren Bedingungen wahrscheinlich auch so. Eigentlich 4-5 Sterne, ABER: Wie zum Teufel soll man das Ding wieder zusammenbekommen? Wir haben das Teil zu zweit schon kaum in den Umzugskarton(!) bekommen, in dem es kam: Völlige Ideenlosigkeit, wie wir das Teil hätten in den Sack zurückstopfen sollen. Auf dem Weg zur Post ist das Umzugskarton-Format sogar "explodiert", wurde jetzt mit mehreren Umrundungen Gewebeband gesichert und so sieht das nahezu runde Gebilde aus, als würde es an jeder Kante wieder platzen wollen. Klar, Schlafsackbeutel sitzen immer stramm bis sehr stramm, aber das Teil? Wahnsinn. Möchte ich nicht im Zelt oder unter der Sonne versuchen, wir haben es nicht einmal in der Wohnung geschafft. Vielleicht ist in der Produktion die Futterstärke versehentlich noch weiter erhöht wurden, aber so klappt das nicht. -Zur Verwendung als Schlafsack also 5 Sterne, nur leider nicht wirklich transportierbar.

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 así, basta con meter una orilla del sleeping y seguir metiendo el resto del sleeping así hecho bola en la bolsa, sin tener que enrollarlo ni nada, nada más lo metes como puedas y así 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 sí el review: El sleeping está perfecto, perfecto, es súper resistente, muy acolchadito y extremadamente calientito. Yo nunca había visto un sleeping tan grande como este, tan grande y pesado. Pero lo cierto es que es sumamente calientito. Incluso podría decir que está de más de calientito, yo casi no paso frío pero mi novia sí, así 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 líquido creo que mi mismo sudor se fué al piso, haciendo que mi lado quedara mojado, eso sí nunca me había 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 frío, 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 así, 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 así 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 recomendaría si vas a viajar en coche, porque irlo cargando no es opción. Sí lo recomiendo, a mí se me hizo de más de calientito, pero eso te asegura que soportarás temperaturas de hasta unos -5 grados centígrados, fácil.

My Boyfriend is 6' tall and we wanted a sleeping bag that was long enough for him that we could share...this is the ONE! He gets hot feet so he just loves that he can unzip his side at the bottom to let his feet breathe, while I can still have my feet tucked snuggly inside. We tried it out last night in the back yard at -7 C. during a wicked windstorm that rocked the tent all night, we spooned tight in our nice cocoon and we were so warm and comfortable together, it's so nice to have a sleeping bag that we can share. We cannot wait to get out into the woods this winter and experience more awesome warm, cozy sleeps in sub zero temps in our new sleeping bag. It packs up nicely and the quality is #1, we would recommend it to anyone looking for a double sleeping bag that is high quality and lives up high expectations.
