It really is an anti-theft backpack because even the owner will have a hard time going in and closing the bag. If you are running late, forget about closing it and putting in your back because you will be late. The zippers are stiff and if you happen to open it all the way, you have to hold the bag in front of you and try to negotiate with the zippers. Other than that, the bag looks good, light and looks durable but I will have to get another bag for everyday use. I am going to keep this for travel and when I move to PH so I can give the pickpockets a hard time and not just me.
