Kept me alive
Through unfortunate circumstances I became homeless and had no choice but to sleep in a tent for a year.I live in Maine and managed to live in a tent through the winter due to this sleeping bag. If I recall correctly, the coldest night I remember was 10°F (not including wind chill but I was in a tent so N/A)I was very warm that entire night.I would like to note that I also had a twin size box spring and mattress that I was also sleeping on so I was not on the ground.If you need warm this will do it.I'm 6' 255lbs and I had plenty of room to sprawl out.Quality materials as well. Zipper never once jammed on me.Side note: The picture doesn't do it justice on how good the orange looks. It is a very vibrant orange.

Awesome bag-Horrific stuff sack
Ok. Let’s start with pros. This bag is warm! Sooo warm. I slept in a top and no pants. The interior of the bag is super soft and cozy. I stayed warm when sleeping alone or with my daughter. It was around 30-40 degrees at night. So not super cold. I love it. I don’t like my legs getting trapped in the mummy bag which I why I opted for this one. Love this.Now for the cons. Since it’s not a mummy bag, my neck got cold. No big deal, wore an infinity scarf and problem solved.Now for the never should have been invented part. the STUFF SACK. Designed by a sick person who likes to make people suffer. First of all, I couldn’t even get it OUT of the stuff sack. (This is not my first sleeping bag. I’ve owned quite a few. And always been able to get them back to stuffed.) but this nightmare would not even come out. So I cut it off. Sliced the stuff sack into shredded bits….So now, after using the bag, I decided to use straps to keep it in “stowed” position. But after sliding around across my tent floor like a oiled up wrestler, I gave up and asked a friend for help. As you can see by the photo, it was a joke. It’s double to size it arrived in. I can barely evenly fit it in my closet.Come on now, invent a better stuff sack. Otherwise, 4 stars.

Good bag
I love it. Get a little to hot camping in oregon summer in roof tent. But we just unzip and use like blanket. Much bigger than expected comes with huge duffel bag. It would take up a lot of space luckily we store it in the roof nest sparrow adventure xl

This bag is Freakin’ awesome.
So i saw a review of this on The Outdoor Gear Review & decided to try it out for myself. This bag is YUGE, like seriously. Its f______g ginormous. But once you get in it, that’s a GREAT thing. Tons of room. The inside lining is extremely comfortable & the insulation is plush. Ive had this sleeping bag out to as low as 40 degrees & i was extremely comfortable (im a hot sleeper). The zippers & the velcro keeps at the top of the zipper are excellent & the draft guard actually works. The draw pulls around the hood are functional, and the canvas exterior is as d@mn near indestructible as you’re gonna get. If you’re car or truck camping and its not north pole kind of cold, this is an AWESOME sleeping bag for spring & fall camping. I would ABSOLUTELY recommend this bag.

Super comfy
My husband and I tested out the sleeping bag last night and it was great! We put it on top of a blowup mattress and it fit perfectly. I love the lip at the top. It’s a perfect place to put your pillow and then your pillow doesn’t separate from the bag… If that makes sense. It was very warm but not too hot. Super soft! My husband is ‘6.4 and it was long enough for him.
