The outer flap protects the two 
deep inner pockets and the cargo pocket from wandering hands. Covered in Indium, 
and locked in place with the oh-so funky 747 seat buckle, the outer flap zips 
open to reveal a large pocket hidden inside. The zipper looks like it has been 
sewn on at an odd angle, but when you're wearing the Cargo over a shoulder 
the zipper ends up on the level.

The pocket is quite large and 
can easily hold a pile of 8.5"x11" paper, or in this example an NEC Ultralite 
Crusoe-based notebook. Paper! Who uses paper? Most of the time this pocket 
carries the small and bulky things that won't fit in with the more regularly 
shaped stuff inside the bag. It is easy to reach with one hand behind the back 
thanks to some small zipper thingies, and since the pocket is closed on three 
sides, your stuff won't fall all over the side walk when you open it 
up.
The cargo 
pocket
The cargo pocket lies hidden 
behind the outer flap which folds up and out of the way to reveal this pocket and 
two others. In all honesty, the cargo pocket gets abused the most on this bag. 
Inside of it there is a small pocket to hold fragile things in place. The main 
pocket compartment is good for lugging around power adapters or NIC cables 
as it can bulge out a few inches.
Above and behind the cargo 
pocket are two deep pockets which I didn't find for quite some time after 
getting the bag - they are well hidden. The two deep pockets are perfectly 
shaped for holding a CD player and a stack of CD's (discs in sleeves are better, 
though the cargo pocket will hold about 8 jewel cases). In this example below we 
have these two pockets stuffed with a portable CD-ROM and floppy drive for the 
NEC Ultralite. There is a stack of CD's behind the USB floppy drive, but you 
can't really see them.
