its functionality and its ergonomics. For a small bag, you can fit so much stuff in it because it has the same internal design as the big Pacsafe Citysafe backpack. I also love how the hooks for the long strap are hidden inside within the straps because if you use the bag without straps they are not obviously seen hanging, and they are also diagonally opposed to each other thus making the long strap quite ergonomic on the shoulders compared to if the strap was hooked on the opposite ends of the bag.
