I wanted a light weight down bag but didn't want to spend a fortune. After a lot of research I chose this bag. It is 2" longer than most women's bags which meant I didn't have to go to a long bag. I love the extra 1/4 zipper on the other side. I roll from side to side while sleeping and the extra zipper makes it a lot more comfortable. The bag packs down very small which will allow me to easily pack it at the bottom of my tent. It has loops to attach to your pad if you desire. I can't speak to the warmth yet as I haven't tested near 30 F yet.
