Nice
Very nice and warm. My only critique would be you can not fully unzip to use as a blanket. Probably in the description but I didn’t think to look for that.

I was warm!
We were in about 32° when we went camping and I was DETERMINED to stay warm. I do not like to be cold so I layered up and had this sleeping bag, to my surprise I was so warm that I had to take layers off in the middle of the night! This gets many thumbs up from me!

Great sleeping bag for the price
Took this on a backpacking trip and it worked well. Slept at elevations over 10k feet and kept me warm (temperature got into the low 40’s). It is light weight and compact perfect for backpacking. My only complaint is the pocket for your pillow is a little small. My backpacking pillow did not fit when it was inflated.

Ok for the price, but…
I was camping where the night got down to 31 degrees. It kept me warm-ish. I ended up tossing a hand warmer by my feet which ended up heating it up enough and it retained the heat. This was the 41 degree one and I didn’t get a chance to see if it it’s warmer at that temp. The straps on the compression sack that it comes in ripped off upon packing it up after the 2 day trip so I will be returning it and investing in a more quality bag. Overall, for $30 you can’t complain vs the $200-800 cold weather bags.

Using as an inner bag for cold weather camping
I'm using this differently than most people, as it's the inner bag, inside a 4 season bag, the whole thing wrapped around with a 95% wool blanket. I like it as it warms up very quickly unlike the 4 season outer bag. Last night it got up to 40º F and I got too hot and had to remove it. I'm surprised how well it has been working. I've been sleeping mostly outside these days and it adds a lot of warmth to my sleep system. I'm happy with it. Maybe I'll try it alone to add more to this review.

Impressive for price
I was pleasantly surprised at the quality of this sleeping bag. Makes for a great starter bag if you like to backpack. It is a bit heavy and bulky but the positives outweigh the negatives.

As described
It seems warm and is as described in the specifications. I was surprised to see that it is actually as big as it says it is, I am 6’1” and it fits me with PLENTY of extra room. There is an internal flap to keep the zipper from being drafty, and there are two zippers to to vent the foot box while still having the bag zipped up. There is also an internal drawstring that tightens down around the neck area as well as one around the hood that tightens around the face to keep in as much warmth as possible. The tech pocket and pillow pocket are both on the small side, but for the price it can’t be beat
