Waterproof main compartment. Excellent condition, like new, everything works as it should. Interior is as clean as new, my household is smoke and pet free. I got an R20 which holds everything I care to carry (I no longer ride, now only on bicycles). Kreigas are great backpacks, there is no weight on your shoulders and they snap on easily without any adjustments (once they are set to your dimensions). $165 shipped USPS Priority CONUS Would trade for camera equipment.
