Smile at grannies on the bus while you listen to a disturbingly dark song about demon succubus invasions piped to your ears from the Burton Metal Backpack's sound pocket. With your music and with your skateboard strapped to the back of your Burton Metalhead, all you lack is a cold beer. Thank the dark overlords that Burton added a bottom cooler pocket so that you can pour a few down your throat and scream like a crazed beast out your bus window and into the black night.
