The B0 SLIM is obviously the thinnest possible FLEX SYSTEM configuration. The "iPad bag" because works so well as an ultra-thin computing and personal bag - a "man purse" if you will. The B0 is simply the POCKET CAP FRONT and the FLAT CAP REAR modules zipped together. It has no definable interior storage dimensions since it is just two End Caps put right against each other, but the flexible nature of the parts allows one-half inch to three-quarters inch of flat items to fit inside between the modules. The iPad (or other tablet) is most commonly stored inside the long slip pocket on the back of the FLAT CAP REAR, and then the space between the two modules has the capacity to store a 13" Ultrabook laptop or a thin stack of Manila folders for documents, or a magazine or two. So it is possible to carry a thin laptop AND an iPad with this configuration. The B0 SLIM also serves as the obvious starting point for all other configurations. You can add and remove space as necessary just by adding different Center Sections. It is possible to carry the B0 using both a handle and a SHOULDER STRAP because of a clever (and Patent Pending) clip called the "D3 CLIP". A pair of D3 CLIPS attach to two loops on the top (or another set of loops on the side) of the bag. And then the SLIM HANDLE and SHOULDER STRAP attach to those D3 CLIPS. See the Gallery for photos. Storage on the B0 starts with the POCKET CAP FRONT: The POCKET CAP FRONT acts like the "hub" for your entire FLEX System. No matter which configuration you carry you'll be attaching the POCKET CAP FRONT to one end of your bag. And it's the "hub" because it holds all the important small stuff and tech stuff and personal stuff that you want with you no matter what. If you change configurations, you'll always move the POCKET CAP FRONT to the configuration which means you'll always have all this key stuff with you, without any repacking or reloading. PCF: The POCKET CAP FRONT module offers a variety of pockets organized into three "main" pockets and six "secondary" pockets for a total of nine small pockets on the front panel. In these nine pockets you'll store all the cords, cables, chargers, batteries, stylus, memory cards, USB drives, etc, for all your electronic gear. All these important items will finally be separated and organized like you've always wanted. Not to mention space for your wallet, keys, cellphone, business cards, multi-tool, glasses, pens, markers, and things like Ibuprofen, Chapstick, bandaids, etc, and even your digital camera. There is also a flat half-height slip pocket on the inner surface of the module where you can stow an important document or two like a copy of your medical or your passport. The FLAT CAP REAR module offers two flat pockets on the outside, and one flat half-height slip pocket on the inner surface of the module. The primary outer pocket is accessed from the top and has a cover flap that is secured with Velcro. This where you'll likely store your iPad (as long as it's not in a thick case), or a manilla folder or two for some documents, or a magazine. There is a second flat panel that covers two-thirds of the outside of the main panel that is broken into two halves - an upper panel and a lower panel. By default, the bottom edge of the upper panel is "tucked" into the top edge of the lower panel. This allows both panels to act together as a single slip pocket that works great for sticking a boarding pass or other simple paperwork here. If the top panel is "untucked" from the bottom panel, this allows the telescoping tubes of a suitcase or folding cart to pass through and the panel serves to secure your bag to those tubes (especially when this FLAT CAP REAR is attached to other modules to form bigger bags like the B2 COMPUTE, B4 SWIFT or the B7 FLIGHT). Then, when you're done putting your BrightLine Bag on top of your suitcase, you can just "tuck" the top panel back into the bottom panel and it becomes a slip pocket again. The B0 SLIM comes with a SHOULDER STRAP, and also a SLIM HANDLE KIT. (Note that the B0 does not include a MAIN HANDLE - it isn't necessary.) The SLIM HANDLE KIT consists of a SLIM HANDLE, two ADAPTER LOOPS, and four D3 CLIPS. This SLIM HANDLE KIT will be necessary in order to carry the B0 SLIM since there are no 1-inch quick-release clips for the Main Handle or SHOULDER STRAP on the B0. Follow the included instructions and you will be able to install two D3 CLIPS to allow the use of BOTH the SLIM HANDLE and the SHOULDER STRAP. (The remaining two D3 CLIPS are spares.)Dimensions: 2X12X14
