Stop fighting with your zipper and say goodbye to getting your hair caught in hook-and-loop tabs. The Sierra Designs Backcountry Bed 700 Dridown 20 Degree Sleeping Bag will revolutionize the way you backpack. By doing away with the zipper altogether, Sierra Designs not only reduces the weight of this bag, but makes a more comfortable sleeping experience. As the name implies, an incorporated comforter mimics the delicious feeling of being at home in bed. Tuck that blanket around your neck, or toss it down when the sun heats your tent up in the morning. If it gets pretty toasty, but you're insistent on sleeping in, you can also pop the foot vent open for an extra draft. You tend to toss and turn at night, and you like to roll over a dozen times before falling asleep. Thanks to a sleeve for your sleeping pad, you can totally get away with that now. Roll your heart away, and never fear waking up on the cold, rocky ground again. Also, if the temperatures dip below freezing, you can toggle the comforter to the sidewalls, tuck your arms into the insulated sleeves, and cinch the hood down for that cozy mummy bag feel that keeps you warm and feeling safe.
