I purchased this bag primarily because I wanted more of a briefcase aesthetic than a backpack aesthetic and function. . It serves that purpose well.
I use a briefcase functionality much more than travel bag functionality.
The packing style is recommended by Tom Bihn doesn't really serve that purpose in that it involves opening the compartments then opening another packing Cube to acccess items.
I found this Surblue Bedside Caddy Organizer Storage Bag Pocket item on Amazon at 18" wide is a perfect fit and works perfectly my w small pouches amoungst other items that fits ideally and are an easy grab.
It fits the entirety of the front compartment. Clothes are in a medium - large packing Cube with a few other things in the back compartment. Middle compartment remains empty unless a purchase items to take home. Pens and like items are in the outside lowest pocket. 8" Tablet and flat work folder is in the outside top pocket. Middle pocket empty.
No bulging. Immediate access to all I need.
