Introducing the most versatile and intuitive sleeping bag design on the market: the Sierra Designs Backcountry Bed Women's Sleeping Bag 800 Duck DriDown 2 Season. Free of extraneous hardware, the versatile, oversized comforter is free to be tucked into or pulled out of the bag opening, adapting to any of the sleeping positions you're used to at home, whether that's back, stomach, or side. Adjusting to variable temperatures throughout the night is equally intuitive. Tuck the sides of the comforter snugly around and beneath you when the temperature drops, or pull out and tuck back the comforter during warmer nights. It's the ultimate in flexibility and comfort. Designed to eliminate the headaches of the traditional mummy style sleeping bag, the Backcountry Bed performs more like your bed at home to provide you with the best night's sleep you've ever had at camp.
