The 2025-26 FC Basel home long-sleeve shirt by Macron features a traditional red and blue vertical striped pattern with a modern, curved twist inspired by the currents of the Rhine River. Built on a dark blue base, the jersey showcases four vertical red bands that curve outwards at chest height, mimicking the shape of the Baslerstab. The design includes a dark red crew neck, navy blue sleeves, and the official club crest on the chest, blending local heritage with high-performance fabric innovation.
