Here you can see the laptop case at left, the main bag at the center (more pockets!), and the cover at right (with even more pockets). It's in this position that you send the bag through the X-ray machines at airports.
Here you're looking at the main storage area for the bag, where you can either put clothes, gear, or anything else you want to carry. The thing in the center is the Freudian Slip, which is a organizer for paperwork and pens. The rings at top can be used to attach keys or smaller bags containing cables.
Wow, look at all of those pockets! There's storage space for pens, business cards, even a cell phone (although I always want my iPhone closer at hand). On the other side are two large open pockets for paperwork or file folders.
These are splash-proof zippers, meaning that water or other liquids splashed on them won't be transferred to the inside of the pockets. The cover material (red) is very rugged and puts up with a lot of abuse.
On the back side of the Checkpoint Flyer are two pockets. The one shown here is the perfect size for a boarding pass, while the one to the left is magazine-sized. You can also unzip the bottom of the magazine pocket to create a sleeve that fits over the handle of a roller bag.
Here my main suitcase (at bottom) has its collapsible handle deployed and the sleeve on the back of the Checkpoint Flyer is wrapped around the handle. I can move all my gear with one hand, rolling it all on the suitcase wheels. Nice.
