I'm still pretty new to the ultralight outdoor gear market so I was kind of surprised how small this is when packed up. The fact it comes with it's own compression bag is a real bonus. For a lightweight and affordable sleeping bag, it's quite nice
It is pretty thin, but then it's not intended for cold weather. If you will be out in anything lower than a chilly night, bundle up because this won't do the trick. The material and build quality seem pretty durable for what it is. I am quite tall at 6'1" and I fit comfortably inside. I haven't had the chance to really put it to the test yet with an extended bike tour but as soon as I do, I will update my review

Honestly probably the sleeping back I take on most trips now. It packs into a tiny stuff sack. I can place it in the main compartment of my pack and leave the bottom for my tent. It's lightweight but it does keep you very warm. It does completely unzip to create a blanket as needed. I just took this out on a camping trip and it did very well.
The downsides are that the waterproofing is only to a point(as all waterproofing is) you aren't gonna sleep in a puddle with this thing. But with a small drizzle for a small amount of time you'll stay dry.
The other thing is since it's so small there's a chance you struggle to fit in it. If you have very broad shoulders you might find it difficult. If you are someone to likes lots of wiggle room in your sleeping bag this might not be for you. I find I have plenty of space even with it being a little tight around the shoulders. I'm 5'8" and it worked great for me. But if you're pushing past 6' I could see it being an issue.
Overall a great sleeping bag for pleasant to moderate weather. I'd hesitate to take it on any trips in the winter for near freezing temperatures. But for most use cases it's absolutely wonderful.

Compact, light weight and easy to repack.

This is a “warm weather” light weight sleeping bag! It’s VERY thin as far as internal stuffing. For sure, no cushion for sleeping on ground! It is NOT meant for camping in cool, let alone cold weather climates! It will not keep you warm at night unless you are somewhere which doesn’t get below 65-68 degrees! The bag is only rated to 60°F.
Don’t get me wrong. I am happy with this bag for the price & my purpose. Hence the five star rating. Purchased bag for car’s emergency kit. It stuffs into a very small compression stuff sack (which is also very nice & well made), taking up very little space!
I would NEVER use as my primary camping sleeping bag. I’d freeze! May be good for sleeping at someone house as long as you are sleeping inside.
Over all, bag looks well made, is wide enough to fit an adult of average size, I’m 5’.5” and the bag goes way over me! Someone over 6ft would still be comfortable in terms of length.
For an emergency bag it’s perfect! I figure putting this bag inside one of those “Mylar emergency” sleeping bags would do in a pinch till help arrives. Emergency Mylar sleeping bags are only a large sheet of Mylar sealed into a rectangular sleeping bag shape opposed to the “Mylar blankets”.
So yeah, I’m happy to have this bag for my emergency kit!

Was a bit small for me being a full sized man. But definitely did it's job once inside. Was very lightweight and worked in any weather above 50 degrees very well.

Excellent product packs away easily and provides warmth on short trips

I've had this sleeping bag for 2 full years now and have used it on several camping trips in the Northeast US.
What I love about this bag is how compact it gets when stuffing it into its pouch. I keep it under the rear seat of my truck but it can easily pack into a backpack or other container for storage. The material has held up well, and it doesn't seem to hold on to any sort of odor. Nothing has broken and it looks and functions like new. I find the bag to be a good size and it's spacious enough for me to roll around at night even if I'm layered up inside.
A couple of small gripes are that the zipper sometimes gets caught on the material when zipping quickly, but not really that big of a deal. The bag also has a hooded part that is supposed to go around your head to keep you warm, but it's too baggy and doesn't stay on your head at all. I wish it was tighter with more elastic tension. I also wish there were two zippers so I could unzip the bottom if my feet get hot. There's only one zipper, so you'd have to unzip the whole thing.
This bag is NOT meant for cold temperatures. Anything lower than 55F at night and you WILL be cold. I just got back from a trip in NH in June, and I was still a little cold at night and had to use an extra blanket. Last year, I did a trip in April and slept with 2 layers on, and was still frigid enough that I was scrambling to cover myself with anything that I had laying around (towels, clothes, etc).
If you're camping in early/late season and you expect temps to be in the low 50s or lower, this is not the bag for you, even if you layer up. Spend a few bucks more and get something thicker. This bag is great for summer, or warmer areas of the world where temps stay above 55F at night.
