Our family is part of a small scout troop and we purchased most of our camping gear here on Amazon as our local store went out of business years ago. We camp every month except in August in various weather conditions. Our young kids pitch their tent in winter often on ice and snow. They use the folded up back packing foam mats for ground insulation but these bags comfortably get them though. I bought one for myself to test out on a November 2018 camping trip and was impressed that it worked as well as the one my son had which cost almost $200 more. I bought 3 more for the kids as Christmas gifts afterward. It's 2023 and we are still using those same bags.

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)

This is the first sleeping bag I've ever owned, so I'm being pretty critical. I think the bag is a good investment for the casual hiker, but if I was going to do a lot of hiking, I might try out a higher quality bag and probably go for synthetic fill instead.

I have used this bag well over 100 days in the past year and a half. I noticed allergies caused from the down fill, and it affected my health.

I've washed it twice. It's very difficult to wash. It absorbs a lot of water and becomes extremely heavy --- so heavy that I think it would be possible to damage it by picking it up when wet.

It seems high quality, but there is a noticeable draft though the zipper area that can be very uncomfortable. I ended up sleeping on the zipper a lot to combat this problem.

The zipper gets stuck a lot more than I expected it to. I thought the zipper was high quality, but I guess it isn't as nice as I thought.

I think they could have used more fabric. It's a tight fit, and I'm 135 lb with semi-wide shoulders. If I weighed a lot more, I think it would be a big problem! I own another Hike & Byke sleeping bag with a higher temperature rating (I think it's the 50 degree one?). Anyhow, when I lie in each bag, it feels like the same pattern was used for each bag and the only thing that changed was the amount of down fill in it. That doesn't seem right.

The hood closure seems to be made for someone with a really large face. I regularly had a hard time getting it tight enough as to not have a cold face.

I hope my review helps someone, even if it's the manufacturer. I think the Hyke & Byke company is doing a great thing with their micro loans, and it makes me feel good about my purchase. I think the bags are made in China, though. I'm pretty sure I read that on one of them. I thought they were made in America. I felt a little betrayed. :/

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!!

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.
