I park my D outside daily as I have no garage or covered parking. The Weathershield and Noah Fabric car covers for me last no more than five years. Nearing five years of use they loose their ability to repel water and instead soak up water. Also with five years of outside use they become fragile from the ultra violet radiation and will tear easily if caught on something.
The Weathershield is one layer of thin woven nylon fabric about 1/32" (.79 mm) thick. The Noah Fabric is non-woven and is four separate layers that are mechanically bonded and it's about an 1/8" (3.175 mm) thick.
They both repel water perfectly when new and they both breath well and allow any water trapped underneath to evaporate.
They are about the most expensive somewhere between $250 to $300 with the cable and padlock which is sold separately.
