Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Leaks feathers like CRAZY
This sleeping bag leaks an insane amount of feathers. I wake up covered in feathers every time I use it, and I spend at least 15 minutes having to pick them all out of my tent each morning. This seems like a huge problem as leaking down can reduce its temperature ratings and all of that. It's a good price for what it is, but it does not seem to be a quality product.

Great for couples
This is the "her" version of the his and her sleeping bags; they zip up together and are great for couple camping. I have a more thorough review on the main "his" version of the sleeping bag.

Great, really warm bag
I love Big Agnes and this does not disappoint. Warm and cozy. Compresses small. Not super light compared to some other companies, but worth the comfort.

Gorgeous
The picture doesn't do it justice - the colors remind me of sleeping inside a pollinated flower! So lovely!
