This business backpack has a four section design: a computer section, a clamshell open compartment, an organizer and file section.  The fan file section fits letter, legal size folders, provides additional storage for power cords etc. This case meets TSA checkpoint-friendly guidelines.  The checkpoint friendly section splits open down the middle, isolating the laptop on one side to allow for clear x-ray scanning.  Fits most 15.4 laptops and has Briggs & Riley's simple as that lifetime warranty.
