St Mirren have released their Third football kit for the 2025/26 season, produced by Macron and created through a supporter led design process involving SMiSA members. Nearly one hundred submissions were received before a shortlist of five concepts was selected for a final vote. The winning design, created by Jordan Byrne, forms the basis of the new Third shirt.

The St Mirren football shirt presents a full purple colourway with a repeated Paisley inspired pattern integrated across the front, back and sleeves. The St Mirren crest sits on the left side of the chest in a monochrome finish and the Macron logo is applied on the right. A fold down collar is included, featuring a small buttoned placket.

Primary sponsor Consilium appears across the chest with Ultimate Home Solutions and Vertu positioned on the upper and lower back. The sleeves carry additional partner branding. A silver Paisley motif is placed at the top of the back, positioned below the collar as a distinctive design element.

The shirt is matched with purple shorts and purple socks, completing the third strip that will be used throughout the club’s 25/26 campaign.
