In short, all the details you'd find in much higher priced bags for an entry level price. This is a warm-weather bag though, so don't push your limits.
Pros: lightweight; compact; nice features at the pricepoint
Cons: warm-weather uses only
This is a good summer bag or for warm climates. I would not want to use it below 50 degrees, since I tend to sleep cold. Living in south Florida, there's not much opportunity anyways.
I can attest to the fact that in a hammock, I slept pretty cold in this bag and I don't think it got below 55 that night. But on a similarly cool night, I was toasty in a tent. Synthetic is a better choice for wet and humid environments, i.e. the Everglades.
Other features: the zipper is excellent... engineered well for less snags, the fleece lining is nice, pull cords are quality, it has a pillow-pocket in the hood, and there's a surprise fleece pocket/insulation in the toe box...you can stuff this with clothing to warm your feet.
Also, it came with a quality 20L compression sack, not just a simple stuff sack. The sack is way too big for just the bag, so it leaves ample room to throw some clothes in too. With the sack it comes to around 2.5 lbs, closer to 2 without the sack. The tag says 1050 g. It seems somewhat large for a woman's bag...I'm 5'9" and 130 lbs...plenty of room, which is not always a bad thing.
Finally, the light blue material of this bag is bound to show dirt more easily.
