A convertible backpack having an anchoring loop centrally disposed near the top of the backpack on a back panel. A single shoulder strap connected to the backpack at both ends and passing slidably through the anchoring loop at its middle dividing the shoulder strap into a left portion and a right portion. Accordingly, the backpack can be easily converted from double shoulder wear, to single shoulder wear, to across the chest wear.
