Query: on the go backpack

I am pleased with my purchase. It has enough room in the bottom compartment for my Cannon digital camera and enough room for about four standard lenses. The top compartment is roomy enough to store extra things, for example video recorder, or a light jacket, or just extra stuff. It also has two pockets on the side for your water bottle. If you're looking for a "camera" backpack, this would be a good choice.
