Abstract
Abstract An accessory article for use in combination with a sleeping bag which article is foldable into a lightweight, compact package for convenience in carrying, especially by a backpack camper. The accessory article comprises a folding frame composed of at least three generally C shaped elements pivotally connected at each end. A tubular body open at one end and fabricated of a water impermeable, flexible material on the bottom and of a flexible porous material on top having sufficient pores to permit passage of air therethrough but the openings being of a size smaller than common insects to keep insects and such away from the person using the sleeping bag and accessory article. A flap of water impermeable material is attached to the closed end of the tubular body and attaching devices are included on the end thereof. In using the article, the frame assembly is opened and the head end of the sleeping bag is placed over the pivot point of the frame and the tubular body is slipped over the frame and head end of the sleeping bag. The flap may be left open or closed when desired such as in rainy weather.
