New Era partners with Big League Chew to bring Arizona Diamondbacks fans a fun new hat for game day. The A-Frame 9FORTY Adjustable Trucker Hat features a unique design, with a high-profile pinched shape thanks to the merged front crown panels and mesh mid and rear panels for added breathability. With embroidered graphics that pop with raised details, a contrast-color undervisor and a Big League Chew pin, this hat is sure to add the perfect stylish finish to any outfit.
