Spend a night with Big Agnes Roxy Ann and youll look forward to sleeping in the backcountry. The Big Agnes womens Roxy Ann 15 Degree Sleeping Bag System for Women is different than sleeping in the traditional sleeping bag on top of a sleeping pad. The Big Agnes unites the two. The pad not included slides into an integrated sleeve on the bottom of the bag. The Big Agnes system eliminates the unnecessary bottom insulation and replaces it with a sleeve to accommodate the pad which provides the insulation. This design provides a secure foundation and keeps you on the pad all night. The Roxy Ann Sleeping Bag has 650 fill goose down insulation, with a rectangular shape that offers more room in foot box and shoulders, gives an extra 2 inches of girth in hip area, and an extra 2 inches of length in the foot box.
