In September 1971, the Orioles became one of the first teams to wear something other than the traditional home white or road gray jersey when they introduced the all-orange uniform.
The uniforms were a product of the ¡¯70s, when baseball teams began introducing bold and bright colors, made possible by the introduction of polyester in the uniform creation process. The 1971-72 Orioles orange ¡°double-knit¡± uniforms used traditional uniform construction, with button-front jerseys, and the pants had belt loops.
