This is my first Amazon review because I love this bag so much. It's everything I wanted, durable, tough, with pockets and sections I actually use. The zippers feel really strong and durable too. I expect this bag to last a long time. Top of the list, however, is the USB connection to my battery so I can walk to and from work appointments with my phone being charged. I travel a lot and need to use maps and rideshare apps which take a lot of battery power. The amount of times this has already saved my battery life has been so valuable.
