Comments about Big Agnes Pearl +30 Down Sleeping Bag - Women's Petite - 2012 Closeout:
Took these bags to Big Bend NP for my daughters and both stayed warm on a couple nights where the temperature dropped to below freezing for a few hours (slept in fleece pajamas/socks). They both sleep "warm" so I'm not sure how the bags would perform where the temperature was sustained at 30 degrees, but for a few hours it worked fine for them. Another thing I like is the integrated pad sleeve that kept both kids on their sleeping pad all night long.
Bottom Line Yes, I would recommend this to a friend
