Todd, my car used to live outdoors. I have two covers, both of which I like very well.
The three-season, breathable cover is made by Wolf. It does a great job of letting the spring rain drip in and evaporate out again. I figured I needed something better than that, and Jimbo in San Diego sent me his Falcon cover.
I use them in tandem now, with good results. The Wolf cover stays closest to the paint, since it doesn't leave a film on the car when I remove it. That might be because I've never washed it and dried it with a fabric softener, or it could just be the flannel it's made of.
The Falcon cover is made with a flannel-backed windbreaker material, and is very good for keeping water out. Together, they're fantastic. I would caution you that neither cover has provision for mirrors, and both are designed to put them on the car with the top up.
If you put them on with the top down and the toneau in place, you might be okay -- but without the tonneau, you'll find both will allow water in as they sag to seat-level inside.
For indoor storage, either brand would be great.
