I purchased this bag after I graduated university and decided to treat myself to a "working world bag" The inside has three seperate compartments. The two outer compartments have a snap closure. The interior pocket zippers close. I can not tell you how many compoliments I have recieved while carrying this bag. And that brings me to its only down fall. You will have to CARRY this bag everywhere. There is no shoulder strap which I miss sometimes when I have my hands already full!

EDIT: I ended up disappointed. The lock fell off the back after 4 months of use (not hard labor mind you). The lock could not be repaired as it broke in three places before it hit ht floor. I was so disappointed as I enjoyed carrying the bag and received many compliments.
