During the day, Mr. Beer is just another backpack. Carrying books and papers from place to place, he hangs on your back, in your car, or in the overhead bin—quiet and unassuming. But when the sun goes down, and all the other backpacks go to sleep, Mr. Beer’s inner animal comes out to play. Armed with a collapsible funnel, bottle opener, misty can dispensing side pocket, and room for 18 cold ones, Mr. Beer won’t make you the life of the party but… actually, yeah, he will make you the life of the party. Remember, nobody likes waking up with stuff written on their forehead…party responsibly.
