New Era 9FORTY A-Frame Oakland Athletics Battle of the Bay Upside Down Pink UV Snapback Hat – White/Green

Product Description:

A classic Oakland colorway with a bold upside-down twist.

The New Era 9FORTY A-Frame Oakland Athletics Snapback Hat combines a clean off-white crown with a dark green visor and a distinctive upside-down A’s logo embroidered in white on the front.

The left side features a detailed 1989 World Series Battle of the Bay patch, commemorating the iconic Oakland–San Francisco matchup, while the opposite side is finished with the signature embroidered New Era flag.

Flip the hat over and the design gets another standout detail: a contrasting pink undervisor that adds an unexpected pop of color to the classic Oakland palette.

Built on New Era’s 9FORTY A-Frame silhouette, this cap features a structured crown, curved visor and adjustable snapback closure for a customizable fit.
