Here we have the Man of Steel's...um...bottle of aluminum! That makes sense, right? The 7.5 inch tall Superman Blue 20oz Aluminum Water Bottle is BPA free(which acts like Kryptonite to Kryptonians) and boldly features the Man of Steel / Last Son of Krypton, Superman! I don't think Superman needs to drink water on account of a yellow sun, but you need to from time to time from what I understand; you probably want the Superman Blue 20oz Aluminum Water Bottle in order to pay homage to the Grandfather of All Superheroes, Superman!
