These Batman Grey and Yellow Pajama Pants offer the cozy comfort of a 60% cotton/40% polyester blend AND allow you to show your appreciation of all things Caped Crusader! Yellow Bat symbols are printed over a grey, rocky background print. From the smashed "stone" look that outlines the symbols it appears that a big, ol' angry Bane walked by and punched a wall that dared to be adorned with Bat symbols...and punched extra-hard where he saw the symbols. Covering these soft, SOFT pants with print of rocks is surely a stroke of genius, like covering a hammer with pictures of soft kitties. Or printing fluffy clouds on each individual nail in a box. Neither of those things would be as cool or make you as happy as these drawstring waist, button-fly Batman Grey and Yellow Pajama Pants, though!
