Item from Harry Potter by J.K. Rowling
A shimmering silvery cloak that renders the wearer completely invisible — the third Deathly Hallow — unique among invisibility cloaks because it never fades, tears, or loses its power over time.
Also known as: the Invisibility Cloak, Invisibility Cloak, the Cloak, Harry's cloak, the Cloak of Invisibility
