At 18'' by 13'', the canvas Star Wars Stormtrooper Heads Backpack is the official backpack of the Imperial Army! Or would it be Navy...or Air Force? I guess all of the military departments just kind of fuse in the Star Wars galaxy and are mostly referred to as 'banana pancakes'. I think anyways! Perfect for toting around all of your stuff, the adjustable Star Wars Stormtrooper Heads Backpack has an outer pocket, the normal major compartment, and a separated inside. That's probably for your blaster or mouse droid or something.
