Used this camping for the first time this weekend and was very happy with the bag. My 6-year-old daughter used the bag and stayed plenty warm down to the low 30s and even mentioned how comfortable the sleeping bag was.
As another review previously mentioned, it's worth calling out how great the stuff sack is. It compresses the bag to a great size, while also being incredibly easy to repack. I've gone through many sleeping bags over the years and never had one as easy to pack as this one. Loved it!

Firstly, I'll say that I've yet to test it in the field. This is only my initial impression.
First thing, the compression sack was surprisingly impressive. The material is thicker, with quality webbing and buckles. It would easily take a silicon impregnation type water repellant or stand up to being repurposed for other gear (handy, because I usually pack my bed and shelter in its own water tight bag). It easily takes the bag down to about 60% of its advertised pack width without trouble even after repacking it.
Second, the bag itself seems solid. I love the extra room in the foot area, though it's a bit snug in the shoulders. Though not tight enough to be problematic. I'm fairly average size, 5'10", 160lb, with a 39" chest. Other than that, it's warmer than expected, the zips work extremely well, it packs very neatly, and should stand up to some heavy use.
Will update later.
