Nicolas’s guitar-shaped backpack prototype

This guitar shaped backpack is designed for cyclists. It can be worn either on your back by clipping the straps across your front, or the other way around. When worn on your front, the shape allows you to cycle comfortably whilst having easy access to the bag.
Anti-theft element: There is a zip that is accessed from the inside of the bag for valuables. In addition, the main zip has a concave shape, the opposite to what you would expect, making opening it slightly harder for a thief.
