Abstract: Disclosed is a hat with a shade panel that is constructed so as to achieve optimal optical efficiency. The shade panel is adapted to be attached to the crown of the hat via a flexible connecting member. The shade panel is moveable between a retracted position, in which the shade panel is positioned inside a cavity of the hat, and an extended position, in which the shade panel is positioned outside of the cavity of the hat, orienting the shade panel substantially vertically and in close proximity to a wearer's face.
