Lowepro Rezo 160 AW camera bag (black). Fits a Canon EOS 450D-sized DSLR plus one or two extra lenses. Pouches for memory cards, batteries, and plenty of space for filters.

Constructed with water-resistant micro fiber and ripstop nylon. Comes with a weatherproof pouch that can conveniently "seal" the entire bag. Used, in perfect condition. New bag retails for $55. I'm selling mine for $35.
