The 2026-27 Celtic Third Shirt features a warm cream base adorned with an all-over tonal geometric pattern of interlocking circles, inspired by the iconic mosaic tiles outside the Estádio Nacional in Lisbon. This striking adidas design includes dark forest green contrast details throughout, notably on the ribbed crew neck collar and the classic three stripes across the shoulders. A special 60th-anniversary club crest sits centrally on the chest beneath the dark green adidas performance logo, with a single star positioned above to commemorate the historic 1967 European Cup triumph.
