Car Cover Recommendations?

1st post!

Anybody have a car cover? I have a covercraft weathershield HP for my older 4Runner, and it fits well. I just got a Prius and want to get a cover as well. The Prius doesn't have an automatic antenna, and I'm wondering if any covers have a little 'pocket' for the antenna, or do they simply have a hole for it to pass through (kind of defeating the purpose).

If any cover model/brand has an antenna pocket rather than a hole for it, I'd consider it above the others.

My main concern is orgainic debris falling from trees. You know, leaves, dead ants, bird crap, and all the associated crap that drops.

Any thoughts or recommendations will help.

Thanks
