Mens Cagliari Home Football Shirt 2021/2022. The 2021/22 Home match jersey: red and blue, between tradition and innovative elements that make it unique. On the front two large vertical bands: the first all red; in the other - enriched in its upper part by a pattern with hexagonal shapes - red fades into blue which gradually becomes the dominant color. The main color of the sleeves is reversed from that of the band. The back is completely blue, as are the three adidas “stripes” on the shoulders and the collar.
