Read a book, swig a beverage, or organize gear without having to unzip from your warm cocoon! The sleeping bag has a full-length zipper on each side, plus hook-and-loop tabs around each arm, giving you "arms out" convenience. Two zippers also give you more control of ventilation. Hybrid design incorporates mummy-style cinch-close hood with roomier, squared-off footbox. So wiggle those toes, toss and turn a little more, and cherish your new "arms out" freedom!
