Weber Go Anywhere grill - what do you use for a bag?

I don't use a case. I store it in the same compartment with my leveling blocks. My doesn't drip. It has a diffusing plate that catches the drips, so far. The outside has got dirt on it at times from putting it on the ground to cook at times, but otherwise, it's stayed completely clean. I wipe off the dirt with a damp paper towel.
