For the money, what a no-brainer this is.  It's a fanny bag attitude minus the reputation.  It doesn't look like a suitcase in any way, but it holds more than you'd imagine.  The material looks sleek and is rain-proof.  Measurements: 11" H, 1" D and 11" W.

Here's a breakdown: The front has three zip pockets that differ in depth, the top one the deepest.  Top pocket features a cell phone pocket, 2 pen holders, and a miscellaneous pocket.  The deep pocket of this section is large enough to hold an e-reader.

The middle and lowest front pockets do not include extra organizing features, but the middle one is perfect for an address book or something of similar size, and the lowest is for small things (like flash drives).

Flip the bag around and there's one large pocket on the back with a concealed, heavy-duty magnet for closure.  Excellent place for a book or something like that.

On to the main compartment of the bag--the section large enough to conceal and protect an iPad.  The interior is deep and the organization specs are: 2 zipper pockets on both sides; 10 credit card slots, compartments for checkbook, eyeglasses, etc., more ink pen storage, 2 elastic loops for lipsticks.  There's a connected attachment for linking to your key chain, and there's a similar attachment connected to a mini zipper clutch for holding coins/additional cards--an I.D. window on front.  As you've gathered, a wallet isn't necessary when you carry this bag.

The strap is detachable, giving you opportunity to customize your bag.

Here are the cons:
-Sometimes the adjustable nylon shoulder strap twists around in its large silver buckles.
-The bag doesn't sit down like a rectangular bottomed one.  You must lay it down or prop it up.
-Mine is jet black; it will pick up and show dust or lint from surfaces.

This bag is a keeper and it makes life easier.  My favorite thing about it is the organization.
