I personally wouldnt use a cover outside. They move around too much in windy weather...you know what that will do. I have two covers that I use indoors and are both made by covercraft. IIRC the Noah is one of the better ones for outdoor use.
Vehicle Storage Indoor: Dustop TM- 4 layer (polypropylene / polyethylene composite spun bond) cover with maximum dust protection and its soft inner layer protects paint. Light and easy to handle, prevents dings, for inside protection from dust and dirt, ideal for indoor vehicle storage or as the primary cover of a two-cover system (see Strong Winds or Desert Dust Storms) Long Term Outdoor: WeathersheildTM HD- primarily for intense sun environments and long-term storage provides optimum protection from water, dust, tree sap, while providing long-term UVR protection and maximum weatherproof protection from a multi-layer breathable (heavyweight) fabric. Outdoor Weather Protection For fabric see Outdoor Fabric Guide – http//:www.covercraft.com All Weather: WeathersheildTM - single layer construction, maximum weatherproof, superior dry time, breathable, scratch-less, durable, easy care, and packs small and light made from a durable breathable polymer fabric, provides protection from UVR, acid rain, dust, dirt, intense sunlight and wind/storm proof up to force 8 hurricanes. Severe Rain Storms: EvolutionTM (TechnalonTM)- a heavyweight, four-layer fabric ultrasonically bonded to provide more water resistance than most covers as well as UVR protection for extended outdoor use, but especially heavy rain protection. Places a soft, paint protecting finish against the vehicles surfaces, also provide impact protection from nicks, dings, dents and scratches. Inclement Weather: NoahTM by Kimberly ClarkTM — one third less the material weight of the EvolutionTM cover, a three-layer fabric ultrasonically bonded to provide more water resistance than most covers as well as UVR protection for extended outdoor use, but especially heavy rain protection. Places a soft, paint protecting finish against the vehicles surfaces Strong Winds or Desert Dust Storms: Gales or strong winds and desert dust storms can buffer the car cover causing surface marring, wind blown sand, dirt or grit if it gets between the paint surface and a wind buffered cover will cause surface scratches. To avoid this use a Dust Stop™ as a secondary cover, this tight fitting cotton fleece lined material will protect the surface, then use a Weathersheild™ as the primary cover for weather protection. Both of these covers are made of a breathable material so moisture or condensation will not be trapped between the covers and the surface Two-cover system: During high winds or prolonged storage the use of this system will avoid paint surface marring from the cover being buffered by high force winds (Hurricanes) 1.Dustop TM Four layer cover with maximum dust protection and its soft inner layer protects paint from marring 2.WeathersheildTM - single layer construction, primarily for intense sun environments and long-term storage provides optimum protection from water, dust, tree sap, while providing long-term UVR protection and maximum weatherproof protection from a multi-layer breathable fabric.
