Our Chicago 2024 Premium Singlet is a nod to the history of Chicago with our own twist. Like the city itself, it features a grid pattern of varying scale juxtaposed on the left side by an organic water-like print. 

Nestled in the heart of the United States, Chicago was built at the intersection of the Wild West and the established East Coast. Railroads & labor powered its early growth. The Great Chicago Fire created a defining moment of redemption and a radical rethinking of its landscape. Now, Chicago is a global hub of commerce, creativity, and culture.

As athletes, we engage with Chicago’s iconic features, the Lakefront, Grant Park, and the brick structures, each of which we incorporated into the grid design with subtle nods.

Celebrating the spirit of international competition, our Cœur Brisé collection (here) leans on French fashion and our own brand identity. The stripes are a nod to Parisian style and the multi-color blocks at the upper back are a twist on the Internationalist Kit we launched in 2021.

Debuted on our cross-country exploration, Represent US (here), featuring Jaeschel Acheampong’s creative journey from Boston to trials in Eugene, the eye catching collection (here) features refined nostalgic embroideries and bold postmodern takes all featuring the colors of international competition and unity through sport.
