An aerodynamically stable, form fitting, vehicle top covering system that includes a rectangular shape of fabric attached at opposite ends to spars. The ends of the spars are secured at the ends of the vehicle, typically under the corners of the bumpers, with self-retaining hook and strap assemblies. The spars may be designed to bend and thus create differential tensioning of the fabric by tensioning means, causing it to be draped over the top surfaces of the vehicle in a compound curved, aerodynamic configuration that does not require side tie-downs in cross winds. A self-retracting version has small diameter support extensions, at the ends of a roller spar, that allow extra space for the increased radial build-up of the cover's lateral seams.
