League: Collegiate Baseball

History: Since taking over the helm as the head coach of the Golden Bears baseball team in 1930, California baseball legend Clint Evans and the baseball boys of Berkeley would go on to win 9 C.I.B.A (California Intercollegiate Baseball Association) championships before winning the very first College World Series played in 1947 over the Yale Bulldogs. Another first for CAL was playing in the first intercollegiate baseball game played on the west coast when they took on the College of the Pacific on November 6th, 1886 and played to an 11-11 tie when the game was called on account of darkness (27 years after the first intercollegiate game played by Williams College and Amherst in Pittsfield, Mass. in 1859). The California Golden Bears are members of the Pac-12 Conference and currently play their home games at Evans Diamond Stadium in Berkeley, California on the Campus of the University of California.

Measuring Guide

We offer three kinds of ballcap visors:

Pre-1940 ballcaps were made with soft visors so players could fold them up and put them in their back pockets. Later visors were done in standard (stiff visor) or short (also a soft visor). Check the product details to see which type of visor each cap has.
