Bill,
Tyvek is a patented material that was developed to let moisture out and not
in... It has a one-way membrane that allows it to do that! They wrap houses in
it. That's probably the main draw as far as selling car covers made from it. It
will breath if it isn't put on upside down...
Frank can probably tell you a lot more about this stuff.

a TYVEK cover will keep dust, dirt and moisture off the car, BUT they don't
breath. it will trap moisture under the car (if you live in a high humidity
area of the country) and eventually cause ROT problems.
