This bag is of high quality and durable for everyday use. It has 3 compartment which is fairly standard, with an expandable main compartment (zipper) very convenient. The rear compartment to protect computers and tablets is great but I find quite dangerous closing that completely opens to the bottom: the first use of the files off the computer all fell to the ground in the middle of the line of boarding the aircraft. Now I am used to but a protective bellows would be welcome.
