I bought this bag because, as a commuter, I wanted something that had a significant amount of space but also made carrying easy. This bag transitions from a messenger style bag to backpack for the trek from the train station to the office and back to provide a more professional look. It also is incredibly durable. I blew through 5, High Sierra XBT TSA Messenger Bags, all under warranty, but after the 5th I called it. I am still using my DTBG from 18 months later, no issues.
