While the color scheme has remained steadfast, the helmet's design has evolved over time. In the early days, the Bears wore simple helmets with a single stripe down the center. As the team's popularity grew, so did the complexity of their helmets. The iconic "Script Cal" logo, featuring the university's initials in a flowing script, became a staple on the Bears' helmets, often adorned with a bear head or paw print.

The base shell colors have variesd from the mustard gold color, to white, matte black and even a season of gloss black helmets. The logo adorning the side has varied as well including the white block letter "C" enveloped in a dark blue oval, the the word"Cal" written in script.

The stripes down the middle had a very unique arrow shaped design at some points during the early 2000's and 2010s.

In recent years, the Bears have experimented with various helmet designs, including throwback uniforms that pay homage to their historical roots. However, the "Script Cal" logo has remained a constant, a symbol of the team's tradition and identity.
