The design of Pro Bowl uniforms is changed every two years, and the color and white jerseys are rotated along with the design change. This has been Pro Bowl tradition since the switch to team specific helmets, which started with the January 1979 game. The two-year switch was originally created as a marketing ploy by Nike, and was continued by Reebok, which won the merchandising contract in 2002. Nike subsequently won back the contract in 2011.
