Leaked: Mexico 2026 World Cup Third Kit — Adidas x Someone Somewhere

TL;DR

• Adidas have teamed with Mexican social brand Someone Somewhere on a black third kit for the 2026 World Cup, with artisan-drawn ‘M’ and ‘X’ graphics across the body.
• The Trefoil and the Three Stripes are rendered in red, white and green — a direct nod to the Mexican flag rather than Adidas’s usual mono branding.
• Long-sleeve and short-sleeve versions are both expected, with retail availability targeted for late May or early June 2026.

The Leak

Pictures of Mexico’s 2026 third shirt have surfaced in the run-up to the World Cup, and the reveal confirms a collaboration that had been rumoured since late last year. The story was rounded up by Footy Headlines, with imagery showing both authentic and long-sleeve cuts of the shirt.

This is the third piece in Adidas’s Mexico cycle for the home World Cup, and the first to involve a co-branded build. The home and away shirts have already been confirmed via separate leaks; this third kit is the one that swings hardest on identity rather than on football heritage.

Design Breakdown

The base colour is black across the body, sleeves and shorts. Across the chest and sleeves sit Aztec-influenced ‘M’ and ‘X’ motifs drawn by rural artisans working with Someone Somewhere, the Mexican brand that has built its reputation around supporting craft communities outside the major cities.

The Adidas Trefoil — yes, Trefoil rather than the performance Three Bar mark — sits on the right chest in red, white and green. The Three Stripes run down each sleeve in the same tricolour split, breaking up the black base without the kit losing its dark identity. The collar is a slim crew style and the cuffs are kept clean, letting the graphic work breathe.

The federation crest takes its standard left-chest position. Shorts repeat the artisan motif on one leg and carry tricolour Three Stripes down the side seam.

How It Compares

Set against Mexico’s most recent third shirts, this is a sharper turn. The 2022 World Cup third was a tonal away build that leaned on Aztec calendar motifs printed across green; this 2026 piece keeps the cultural reference but pushes it through a streetwear filter via the Trefoil and the artisan partnership.

It is also Adidas’s clearest co-branded national team build of the cycle. Mexico’s home and away shirts hold a more orthodox federation look, which makes the third the kit where Adidas have given themselves room to play.

When Can You Buy It?

FAQ

Is this the real Mexico 2026 third kit?
The leaked imagery is consistent with Adidas’s usual pre-launch sample shots and matches the Someone Somewhere collaboration that had already been signalled. Adidas have not yet released an official campaign, so treat the design as confirmed via leak rather than via official launch.

When does the Mexico 2026 third kit release?
Late May to early June 2026, ahead of the World Cup window. Long-sleeve and short-sleeve versions are both expected at launch.
