The first cover portion is folded over the body portion and fastened thereto along the bottom and at least a part of the side edge of the portions. At least a part of the second cover portion is folded over the first cover portion and body portion. The second cover portion serves either as a foldable flap which can be folded over the first cover portion to provide extra warmth or as the primary cover in more temperate sleeping conditions.
