The bag is also provided with an outer bag covering substantially the entire covered pad for defining the sleeping bag. Storage pockets form part of the bag at the foot end outside the sleeping bag for receiving personal items. The sleeping bag may be rolled into a compact tube shape, with ends secured by retaining clips, and with an integral shoulder strap for carrying the mat.
