Abstract: Embodiments of a vehicle top cover are shown and described, each having a roof panel and two flexible side panels that form a vehicle-top shape and a means for holding down the rear of the vehicle top cover on the vehicle. The roof panel covers most of the front window, roof, and back window, and is held down on the front window by the windshield wipers or, optionally, is tied to the wipers. The side panels extend from the roof panel and are shut in the vehicle doors to secure the cover to the vehicle and to hang down inside the vehicle interior along the inside of the side windows. The rear edge of the vehicle top cover may be held down by a flap or a weighted flap that is shut in the trunk or by a weight attached to the rear edge of the vehicle top cover that lies on the outside of the vehicle. The flap may also be a stuff bag which is turned inside out and stuffed with the roof panels and side panels for storage.
