Mauricio Pochettino, the USMNT coach, has worn the same plain blue overshirt to all four of the team’s 2026 World Cup matches to date.

While nondescript, the garment has managed to inspire lots of fan commentary—some see a fishing shirt; some see a mechanic’s uniform; others see something a dad might wear to happy hour at his corporate job.

As the USMNT keeps rolling, however, a consensus has seemingly been reached: The shirt, made by BOSS, is a lucky one.

And the shirt’s newfound fame is boosting sales for the brand

BOSS told Front Office Sports that initial inventory of the shirt—which included hundreds of units—sold out “within days” of Pochettino’s first appearance in it during the USMNT’s 4–1 victory over Paraguay on June 12.
