Lowepro Rezo 180 AW
Crutchfield Customer Review (What's this?)
I already own a smaller Lowepro, so knew I would like this one, and I do. The integral emergency rain cover is a good idea (as long as I remember where to find it!). The only improvement I can think of would be to put an outside flap over the main compartment's zippers. This would add protection from elements not severe enough to pull out the rain cover.
