Frank Caesar – Uncle Girth Chicago x Korea 105C Trucker Hat

Chicago roots. Korean heritage. Uncle Girth energy.

The Uncle Girth Chicago x Korea Hat takes one of Frank Caesar’s most personal designs and puts it front and center on a classic black trucker cap.

Created from Frank’s idea of combining the Chicago and South Korean flags, the design brings Chicago’s recognizable light-blue stripes and red stars together with the Korean Taegeuk and trigrams. Beneath the flag sits “엉클 거스” — Uncle Girth — in clean white lettering against the black cap.

The result is unmistakably Frank: part hometown pride, part heritage, and part inside joke.

Printed on the front of an all-black 105C trucker-style cap, the compact flag design keeps the hat clean and wearable without losing the personality behind it. It’s the perfect addition to Frank’s collection for fans who want something a little more subtle than a full graphic tee—but still unmistakably Uncle Girth.
