Shield Cloak

Shield Cloaks are magical objects created by Fred and George Weasley and sold at Weasleys' Wizard Wheezes. These cloaks are enchanted with a Shield Charm and, when worn, shield the wearer from many light to moderate curses, jinxes, and other unfriendly spells. They are quite useless against the more powerful spells, though, including the Unforgivable Curses.

Originally, Fred and George created Shield Hats as a joke item for their shop. However, after the Ministry of Magic ordered 500 of them for their support staff, the Weasleys expanded the line into Shield Cloaks and Shield Gloves as well.
