Z4 Full Custom Fit Cover – WeatherShield with Door Dent Protection – 2003-2008 from Roadster Solutions.
Per the RS web site:
This is a Full Custom Fit Car Cover which is made of Weathershield® fabric, it is the highest performing fabric available. Best of all it stores in less than half the space of other fabrics. It is extremely water repellant, breathable, dust will not penetrate, and it is UV light resistant. Its water-shedding technology is the same breathable material used in waterproof outerwear. There is no outside lamination or water-resistant coating to wear off. The fabric is spun from polyester and the fibers are fully encapsulated to be water-resistant. Water just sheets off. Take it off after a rain-storm, give it a shake, and the remaining moisture will dry off within minutes. This cover is more compact than other water-resistant covers and fits easily into any washer for cleaning. The Weathershield® fabric offered in Gray (other colors are available on special order). This is a custom fit cover with mirror pockets and it is made specifically to fit your car not one of those one-size-fits-all covers; it fits like a glove. With all our full custom fit covers a storage bag is always included
