A Patronus is a kind of positive force, and for the wizard who can conjure one, it works something like a shield, with the Dementor feeding on it, rather than him.
Think of the happiest memory you can. Was it when you laid eyes on this ominous yet luminous KUNUFLEX™ button down 10 seconds ago? Thought so. Featuring a pack of protective Patronuses™ ready to cast away an army of demonic Dementors™, it is with this shirt that you feel the deepest affinity.
