Sierra DesignsIf you like to move around while you sleep, then the Sierra Designs Backcountry Bed Elite Sleeping Bag is for you. This lighter version of the popular Backcountry Bed is filled with 850-fill, water-re ... moresistant down insulation and utilizes a lightweight fabric to help save pack weight while you're backpacking. By maintaining the same design as the Backcountry Bed, this lightweight version has the same zipperless design and wide catenary-shaped opening for ease of entry. An integrated comforter is designed to conform to your sleeping position, so you can naturally sleep on your side, back, or stomach. Insulated hand and arm pockets give your hands and arms a warm place to stay when the temperatures drop, and a self-sealing foot vent further allows you to adjust to changing temperatures by either pushing your feet through the foot flap, or warming them behind the draft-blocking collar. The sleeping pad sleeve secures your pad to the bag for a complete backcountry bed you might just be sleeping in at home too.
