Also that's an awesome price on Amazon because I paid $100 for mine
I can personally vouch that this cover is really the best of the best. It's 100% waterproof, sunproof, windproof and lasts a really long long time. I keep my bike outside, in the Florida sun/thunderstorms/heat/cold, it's even been out there for three tropical storms and the cover has held up for 5 years!

I've got a lot of places to see! (on the bike) :-)
I got a cheap $11 one from Ebay.
It won't hold up in the elements, but it's good for what I need it to do. Shade in the summer. And keeping the dust off when parked in the storage shed during the winter.

Used to be Red, now it's Green. Open for name suggestions.
I picked up a CycleShell and don't regret the investment. Setup is simple. Full enclosure with vents and quick to deploy and open, too. Packs up pretty simply for relocation, too. Vendor is a great resource.
