Optical me the bag like it very much: subtle color and not immediately recognizable as a camera bag. That was very important to me.
It was also very important to me that the bag is large enough to accommodate a medium telephoto lens. This is also great. A 0.5l bottle would fit in easily.
A mesh pocket on the flap might have been practical to accommodate very small odds and ends, but hand me the front two bags completely.
For the price it is really great. I had to view the pocket "Crumpler Jack Pack 3000". Visually I liked it better and from the processing also. That was me, unfortunately, small to. Had I ordered the pocket bigger, so it would have been twice as expensive. Then I'd rather lose the 30-year warranty and take 5 years.
Very satisfied!
