Abstract: The shelter is produced of a semi-rigid foldable material and can be rolled up into a compact configuration which is easy to carry. In its erect configuration, the shelter includes a generally conically shaped top covering which is connected to a triangular base. Connected to the base is a partial flooring which extends between two corners of the triangle. The occupant enters below the covering through the open floor section and places his weight on the enclosed floor section. This holds the three corners of the triangle downwardly thus causing the covering of the shelter to maintain its vertical disposition. The weight of the occupant causes the shelter to maintain a conical shape. Internal stake loops are attached at each end of the opening in the floor to allow adjustment of the shelter ground contact to seal the opening.
