These are great sleeping bags. They are super warm, and well made. I don't find myself feeling like I stick to the material when I'm hot, like the sleeping bags I used as a kid. Took these on a trip camping in the rainforest in Washington in April, where it's still fairly cold in the evenings. My spouse and I were plenty warm, even when it was rainy and cold outside our tent. We both stayed dry. These bags are relatively easy to return to their carry bag; I recommend stuffing it in, not rolling. Recently,the zipper on one sleeping bag came apart, but we aren't sure if that was due to the quality of the product, or rough use. In general, these are fantastic.

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.

I'm planning on using this sleeping in December on a one week hiking and camping trip. I looked and researched around 50 other sleeping bags and I picked the Hyke&Byke as a go to winter bag to help give me a comfortable sleep and help keep me warm in below 30 degrees nights while in the Appalachian mountains on my winter vacation to defrag from all the 2022 madness. I'm sure I'll be a happy camper!

These are going to be Christmas gifts so they haven't been used yet. But just checking them out they seem to be just what we wanted.

The only thing I didn't like is that it is very slippery - but with that said, the material that it is made out of is very tough - super light - zero degree bag and I saw sub freeze temps at 12,000+ feet, I was chilly at night, but I am always cold - I was happy cause I didn't freeze the way I normally do - great system to cinch opening around face and also above shoulder - the should cinch was a HUGE temp difference and saved me from my normal cold to really being very cold - fit well I'm my pack with its compression bag
