You know Batman's home town of Gotham City recycles...hell, they can't even throw away their criminals! I wonder if that entire city is just a bunch of run-away hoarders...somebody call the Discovery channel! The Batman Gotham Recycles 20oz Aluminum Water Bottle stands 7.5 inches tall and is BPA free...Batman is quite the avid 'Green' personality. My guess is that all that hanging out with Green Arrow started rubbing off! With a metal clip/ attachment, you can put the Batman Gotham Recycles 20oz Aluminum Water Bottle on your backpack, hiking gear, or utility belt!
