You will sleep good down to able 35-40° in this and colder and you won't enjoy the night. 0° is the survival rating. Don't take this out in 15° temps thinking you'll be nice and warm all night.

I'm a bit silly and use this for year round camping as I sleep really cold. It has been fantastic to stay warm when camping for once! (Primarily in the summer farther north in the US where it gets to the 50s in the summer)

Quick Review: Huge Fan of this Bag. For the price it is outstanding, would recommend a down wash after purchase to make it a bit more waterproof. Full Review: I love backpacking in the summer, and was looking to try to get into more winter camping/backpacking. I purchased this for winter camping in near zero or below Zero temps(Duluth, MN). I did my first test on a three day backing trip in Northern Minnesota along the Superior Hiking Trail, overnight temp the first night was between +4 and -2 Fahrenheit, second night was between 0 and -8 Fahrenheit. For sleeping I was using the following gear: Outdoor Research Alpine Bivy - Tent Hyke & Byke 0 Degree Down Bag Alps Mountaineering MicroFiber Sleeping Bag Liner Therm-a-Rest Z Lite Sleeping Pad - Closed Cell Base (R 2.6) REI Cirrus Insulated Air Pad - Inflatable Pad Between Base Pad and Bag (R 2.6) I knew it was going to be getting below Zero both nights, so I was also wearing some R4 long underwear, and wool socks inside the bag. I was also using the Bag liner to add some extra warmth. Overall, the bag performed beautifully! I was quite warm the first night, and actually didn't full zip the bag inside the Bivy. The second night was much windier and a bit colder, so I had the bag fully zipped and the hood cinched up tight(great feature of the bag BTW). Both nights I was comfortable enough to sleep through the night without any issues. Being inside a Bivy, there was a LOT of condensation(ice) in the morning, and the outside of the bag did get a little bit wet, but it dried well under little bit of sun curing the day. I am definitely going to do a down wash treatment on the bag to make a bit more waterproof in the future, though this was not enough of an issue to deter me from using it. If going right to that zero mark and below zero at all, I would definitely recommend a bag liner to add some extra warmth. I slept outside with this in about +5 degree weather(with no liner/long underwear), and was comfortable enough to sleep, but definitely missed the extra liner warmth when I woke up. I would not recommend going to far below zero for safety unless you are really confident in what you are doing. I did have some issues compressing the bag into the Stuff Sac provided, and was able to do it, but it was quite difficult to get it packed all the way in. The second night I used a Sea-to-Summit Compression Sac and it was much easier, so you may want to consider a different stuff sac than the one provided. The sea-to-summit sac was longer and made it easier to pack everything down, and with the compression straps I could get it to the same size as the included bag. Overall: I loved the bag, and for the price point it cannot be beat. I will definitely be looking at more Hyke & Byke bags in the future.

I bought this long bag for my 6'3" 220 lbs husband who has wide shoulders (56" around). He fits it in comfortably. To test it out I (5' 120lb) camped in it once in Yosemite in April for four nights, where temperature dropped to 42 F. Before used, we fluffed it up in dryer for 5 mins with no heat then packed it loosely in a larger bag, and fluffed it up by shaking it out and laid it out for more than an hour. I didn't trust it at first, so slept in it with a t-shirt, a thermal long sleeve T-shirt, a jacket. I got too hot and had to take off layers. The second night I didn't have the Jacket on, I was warm enough. The third night, it said the temperature would drop more, so I put on more layers, and got too hot again. It is the warmest sleeping bag I ever slept in. It was big for me but the extra room did not make me feel cold. My husband camped in it for three nights where temperature ranged from 50 to 45 F. He had a shirt and pants on, and used it as a blanket and slept on a cot without a tent. He was warm in it. My guess is if in 32F (0 celcius) - 20 F (-10C) he would be warm enough if he zipped it up. Material is like those down jacket material you see at Costco. If you could wear those jackets daily, I think it is study enough for the bag. I zipped the zipper with care, so far no complaint about the zipper. update: We have used this bag in cold and windy situation (not sure what the actual temperature was, ~ 40 degree F) for quite a few more times. My husband does not like to zip it up, so when it was cold and windy, he slept with a light weight cotton jacket on a cot (not in a tent) and used the bag as blanket and just tugged the side under his body and feet in the bag and still feel comfortable. two down sides: each time my husband got up, he was covered with down and the odor still presence even though we air dried it. These are the main two reasons that I hesitate to buy another one. If the manufacturer could replace the inner line material to a tighter knit material, maybe down would not come out and the bag would maintain its warming system for a longer period. My only complaint is the bag smelled badly after the first night use and it didn't seem to totally go away after putting it in dryer in no heat setting as recommended by seller (seller was contacted after we discovered the issues). Would have received a 5-star review if it didn't smell bad or keep loosing the down filling. update: the bag is warm, but the odor is present after each used, air dry or air dry in dryer only help if you don't use the bag, if the bag is used for one night, it stinks!! we continue to loose down filling each use. Very disappointed!!
