TRF sells the Covercraft brand, which is a leading maker of car covers. I bought the indoor/outdoor Technalon cover (most expensive) during last year's sale and I have been very happy with it.
The car is garaged mostly, but the times it has spent outside, I have been happy with the results. The cover does well in the commercial washers and dries very quickly in the sun.
You can find the same cover for a little bit cheaper and in different colors (my cover is tan) direct from the mfgr (try google), but it is nice to support our vendors so I did not mind. I may do it differently for the next round, though.
