These uniforms are copies of the uniforms worn by the Golden Bears through the 1977 season, I believe. Cal started to wear royal blue after the '70 or '71 season. I believe Russell Athletic made the originals. Cal pulled a huge upset of USC in '77 in the same jersies. After Mike White left and Roger Theder took over, the stripes on the sleeves were removed. Home jersies simply had silk screened gold numerals. Away jersies had royal blue numerals. Boring. The facemasks were changed in '80 or '81 to royal blue. Theder also replaced the block C with the script Cal. When Joe Kapp took over in 1982, the navy blue returned along with the now famous bear claw with the script Cal inside and the number 100 just below to signify the 100th anniversary of the program. There has been some movement back towards the block C. The baseball team's caps are now the block C. You can purchase them at the ASUC bookstore.
