Definition
A deerstalker is a type of hat often associated with Sherlock Holmes. It's a cloth cap with earflaps that can be tied together either on top of the head or under the chin. It also features a visor in both the front and back. The hat was originally designed for hunting, particularly deer stalking, hence the name. Although famously worn by depictions of Sherlock Holmes, it wasn't mentioned by name in Arthur Conan Doyleβs stories. It has become a recognizable symbol and part of pop culture.
