The Spiderman Kids Backpack w/ Detachable Soft Lunch Box comes in at 16.5'' by 13'' but the fun part is this thing has a detachable lunchbox style compartment measuring 7.5'' by 9''! That's almost as versatile as Peter Parker, wouldn't you say? That guy takes pictures of Spider-Man while being Spider-Man...which I think makes him the original master of the selfie. You'll have all of your bases covered with the adjustable Spiderman Kids Backpack w/ Detachable Soft Lunch Box!
