-The fabric isn't super plasticy, it feels better on bare skin than any of my other bags
-It packs down smaller than they suggest (I got it to 11 X 8.5 X 8.5 without a struggle, which isn't huge but gives a fair bit more room if you're backpacking)
-I love that it has a little zip pocket inside, I use it to keep the battery life on longer trips [without my phone or goal zero sliding around my bag, the body heat helps]
-I haven't been through a rainstorm with it yet but I threw a bunch of water on it, it's definitely water resistant
-I haven't found anything significant yet. are there bags that pack smaller? yes. lighter? yes. but honestly bang for your buck this is an amazing bag
It turns out that this bag was too warm. In the morning when there was ice on the tent fly from the condensation, I found it unnecessary to have my head in the hood, or to have the internal neck seal in place. Frankly, the bag was too warm for the trip. I suspect I could have used the 0F version of this and would have been comfortable. So I am pleased they appear to be conservative with the temperature rating. Another trip with colder weather will tell for sure, but at this point I think they are being honest.
Another plus is that the seams on the outside are offset with the seams on the inside. This allows the down filled pockets to overlap. This means that heat can't escape through them. They also have down filled tubes that cover the zipper. This is all common in all the good down bags I have looked at, so that isn't a surprise. I guess I am surprised at how inexpensive it is while it appears to be as good as it is.
The zipper would snag on the inside zipper draft tube from time to time, but I didn't see any damage and I could get it free fairly easily.
I didn't see any of the down come out of the outside or inside material, but I haven't used it that long yet, so we will see how it holds up.
I don't know how this feels when it is 0F or colder outside, neither did I get the bag wet, so I can't comment on how well it holds up under those conditions
At this point I like this bag, I am glad I bought it.
I received this bag yesterday and wanted to write a review of my first impression. While the bag was in its carrying sack, it was very lightweight and compact! The bright orange was very appealing and it was easy to fit in/out of the sack. I immediately hopped in and it was very soft and cozy with plenty of wiggle room to turn on my side or roll over. I still had plenty of leg room at the bottom of the bag as well. Once zipped up, I felt just like a mummy! I’ve not yet tested it outside in the cold weather, but I immediately felt warmer once I hopped in. I’m excited to test this out and will post an update once I’ve done so! I am a long distance hiker and plan on using this bag for “The Pacific Crest Trail.” Your Company has an amazing reputation and the bag is very affordable in comparison to other brands.
I packed it up the other day for a 1 night backpack trip and it compressed very well. Part of the reason I settled on this bag was the packed size would fit my Osprey Atmos 65 sleeping bag compartment and it was relatively light weight. I was hoping the temperatures would fall father than they did so I could better review the temp rating, but I think they only got down to about 25F. I had no problems keeping warm and had the zipper partially open with the hood off inside a bivy sack. I feel like it has the potential to reach its rating.
One other note, I had a few down feathers in the bag when I unpacked it. Nothing out of the ordinary but I collected the few I could find and ran some water over them in the sink out of curiosity. The mountain dry down works! They did not absorb any of the water.
I like the bag and I am happy with the purchase. I would recommend it to others as a bargain choice but I'm not sure I will buy another one when I need a new one though. I looked at a lot of higher end bags following this purchase and there is definitely a quality difference that I might be willing to pay for next time.

If you are looking for an all around great value winter down bag, look no further!
The mechanism to tighten the neck piece is oddly positioned and if you slip yourself in your bag it falls at face level. I love the inside pocket, ideal for keeping your ear plugs in reach when ready to shut yourself out of everyone else.
