The Center Section Three offers 3 inches of storage and easily carries 13" laptops, some 14" laptops, tablets as well as documents, folders, clipboards, etc.
There is one small accessory pocket on the side panel, accessible with a vertical zipper. It's a good size for pens, markers, highlighters, or spare reading glasses.
The Main Compartment of the CS3 has locking zipper sliders.
There are no side pocket mounts on the CS3.
NOTE: Many of the photos show a small one-inch webbing strap going across the very top of the module. This strap has been removed. It is no longer part of the bag. We removed the strap because it was left over from the pre-FLEX days and it is no longer needed as a secondary handle.
