How many burgers-of-the-day can fit into this backpack? Guess you'll have to get it and find out! Better save some room for fries though. It's very important to have fries with your burgers. Grey backpack from Bob's Burgers features an allover cast and burger print, contrasting lime green web handle, zipper and strap adjusters. The front zipper pocket has an image of the restaurant and all the zippers have rubber cheeseburger zipper pulls. Add to that an interior laptop sleeve and small interior hook and loop fasteing tape closure pocket, and you've got yourself the perfect burger (backpack)!
