[ San Francisco Seals ] ‘57 Pinstripe

This San Francisco Seals hat honors the final chapter of one of baseball’s most storied franchises. Made from 100% premium wool, the crisp white crown with navy pinstripes and deep navy brim draws from the Seals’ timeless uniforms that defined West Coast baseball style. The front features the team’s sea lion emblem, while a 1957 Seals patch on the right side marks their final season before the arrival of the major league Giants. Finished with an adjustable leather backstrap, this piece from Official League’s Diamond Vault Collection carries the legacy of San Francisco’s golden baseball era forward.

The San Francisco Seals were a Pacific Coast League powerhouse from 1903 to 1957, producing legends like Joe DiMaggio, Lefty Gomez, and Ferris Fain before relocating to Phoenix. Named for the sea lions that call the Bay home, the Seals captured 14 league titles, with their 1909, 1922, 1925, and 1928 squads ranked among the greatest Minor League teams ever assembled.
