The Celtic 2025–26 Third Jersey boldly departs from traditional norms with a strikingly modern aesthetic. The jersey features a crisp white base layered with horizontal green brushstroke bands, invoking a hand-painted texture that fuses organic movement with visual rhythm. This unorthodox striping injects a dynamic vibrancy, especially when offset by the bold orange piping along the seams and neckline—a nod to Ireland’s national palette without overpowering the shirt’s clean canvas.
 
The monochromatic crest and minimalist sponsor logo are rendered in tonal green and white, maintaining visual cohesion while subtly allowing the pattern to remain the centerpiece. On the back, the design is simplified to prioritize comfort and breathability, with mesh paneling for athletic function.
