The Roxy Ann is a very comfortable and roomy bag made from quality materials, but she is not a true 15-degree bag. We really wanted to like this bag, and in a lot of areas thought that the Roxy Ann was great, but we spent a few very cold nights out with Roxy Ann, and she did not keep us warm. On warmer nights she is wonderful and we had some great nights' sleep. We enjoy her soft materials and cozy lofty down. Unfortunately, the bag is heavy for what it is, probably due to the large pad sleeve. This is a down bag that is most comparable to other mid-price-range down bags like the Marmot Angel Fire. Both have hydrophobic down and both are in the $250 price range. The Roxy Ann is about three ounces heavier than the Cosmic, probably due to the pad sleeves on the bottom of the bag.
The Roxy Ann is available in some new colors, like the purple shown above. Big Agnes confirmed that tech specs of this bag have remained constant.
