I purchased this bag brand new to use in 30-35 degree nights. After perusing many websites, the temp rating for women should be around 28-31. The nights were 37 degrees and I was coooooold! This brand/bag is not a good choice for women who get cold at night while camping, and want to crawl into a bag and know they will be warm and cozy. Also, this brand/bag is not for a woman with the baby boomer spread. After a couple of kids and the inevitability of aging, no matter how in shape you are takes its toll. I don't think you should have to buy a 0 degree bag to sleep comfortably in 35 degree night temp. All in all, I would not recommend this bag even on sale for $100.
