Used this when I camped on top of MT Rainer. Kept me very warm when it was 29 degrees at night. Super soft, and easy to clean. Rolls up very small and very light for backpacking in.

I used this bag *literally* every single day for an entire summer up in the mountains in Colorado. The first 4ish weeks every night was around 25 F degrees, and later in the summer it was consistently between 45-60 degrees F at night.Pros: Super easy to pack into the compression bag and take it out. I was constantly packing up and packing out, and it only takes a minute or two to do so. Durability is strong. In the warmer nights, I was perfectly warm and comfortable.Cons: This bag is not as warm as it advertised. One night it got down to around 20 degrees, and I thought I was going to die from the cold. True story. During the colder nights I would put two blankets over the sleeping bag and I slept great. This bag is also not waterproof or even water repellant. The morning dew will soak this bag.This was a good bag for me, but there is absolutely better options out there. If you need a bag that's comfortable in 50-60 degrees F at night, you're on a budget, and the water repelling feature isn't an issue for you, this bag is for you.

It’s a little bigger than my older bag, but it is definitely warmer. The zipper quality is better. Very comfortable! Great value for the money. Nice color. I’ll have to see how it stands up over time.

Compré este producto para subir el Nevado Sajama (montaña más alta de Bolivia), en donde se estimaban temperaturas de alrededor de -5°C a -20°C, entendiendo que el rating de 0°F (18°C) es de supervivencia decidí tomar el riesgo, y para mi suerte funcionó muy bien, debajo de mi sleeping tuve una colchoneta inflable que en realidad solamente funciona para temperaturas de verano, y aún así no sufrí de mucho frío. Si se quieren comprar este producto para cualquier montaña de México, lo recomiendo muchísimo, incluso podrían pasar algo de calor, pero no está de más. Algo que igual fue muy bueno para mi es que al dormir me muevo mucho y el tamaño a lo ancho del sleeping bag me ayudó muchísimo a diferencia de muchos otros que suelen ser angostos incluso en las tallas grandes para hombres.

Did camping in High sierra during a rain and snow storm. This kept me warm. Love this sleeping bag. Temps dropped to single digits overnight but i was warm and had no issues . Works as advertised . Light weight, compact packing . Love it. Before you spend few hundreds on a expensive name brand try this , worth a shot.

Bought this for my recent archery Elk hunt in the mountains of Wyoming. Coldest was in the low 30s and was warm. I would recommend some sort of insert blanket for the cold spots when sleeping in one spot then moving around.

Great loft and warmth. Nice quality material and zipper as for durability. The draft collar is nice and thick. It’s not as water resistant to dew as other bags I’ve used but it has enough material to where I haven’t gotten wet into the bag. The value for money is pretty good and I’d definitely recommend it. I appreciate the streamline quality and the cinch bag. It does an effective job at keeping my body heat inside.

Went camping and it dropped to 10 degrees. I had a thin air stress, foam pad, and the sleeping bag. I was surprised in the morning when I crawled out. I would have never guessed the temp. Worked great especially for the price.

I bought 2 of these. One for my 12 year old son and one for my husband. My son is in boys scouts and has taken this sleeping bag on 2 camp outs. The first camp out the temperature reached 21 degrees. He and my husband both were very warm in their sleeping bags. My husband had to come out of some layers to cool off through out the night. The second campout, the temperature reached 9 degrees. I attended this particular campout and I had on thermal undies. At one point, I unzipped a section of my sleeping bag so I could get some cool air. I also took off my beanie. They compressed well and were light weight to carry in on a back pack camp out. The company sent directions on how to care for your bag. It came in very handy because we are all new to camping out.My son is about 4’10” and weighs about 90lbs. We got him the regular size.My husband is 6’3” and weighs about 215. I am 5’4” and weighs about 145. I ordered us the regular size as well. I fit comfortably in the bag and have room to move around. My husband also fits into the bag and doesn’t have as much room but he is able to move around as needed.I purchased these bags because of the price. Since using these bags, a couple other families have purchased this brand for their kids. It is a great bag for a great price.
