USPS Mr Zip Mesh Back Hat - Gray and Navy BlueVintage Never Looked So Good First introduced in the 1960s, Mr. ZIP wasn't just a fun cartoon character he became the cheerful face of a faster, smarter Postal Service. Inspired by the USPS team and this blazing fast mail carrier mascot, we've created this two tone trucker style hat featuring a bold embroidered Mr. ZIP patch on the front. This retro USPS hat features a gray front, and a navy blue bill and mesh back. Perfect for casual wear!
