Which Tennis Players Wear On Clothing

On, the Swiss sportswear brand known for its cloud-soled running shoes, has steadily built a tennis roster that punches above its weight. Rather than chasing volume, the brand has picked out a tight group of players who represent both established stars and the sport's next wave. Here's a look at who's currently repping On on tour.

The Established Names

Iga Świątek has been the anchor of On's tennis lineup since March 2023, and the partnership has only grown in visibility as she's remained a fixture near the top of the WTA rankings. Her clean, minimalist on-court look has become closely associated with the brand's aesthetic, helping On establish credibility in a category long dominated by Nike and Adidas.

On the men's side, Ben Shelton joined the same month, giving On a foothold in American tennis just as Shelton's power game started turning heads. His rise up the ATP rankings has made him one of the more visible faces of the brand's tennis push, particularly at hard-court events in the U.S.

The Rising Contenders

On has also bet early on younger talent. Flavio Cobolli, the Italian now cracking the top 10, wears On on court as his profile continues to climb in a country obsessed with tennis. His emergence has given the brand another foothold in Europe alongside Świątek.

Meanwhile, Brazilian teenager João Fonseca has quickly become one of the most talked-about names in the sport. Already ranked inside the top 30, Fonseca's partnership with On positions the brand well should he continue his ascent — a bet on future stardom rather than current hardware.

A Small but Strategic Roster

What stands out about On's tennis roster isn't its size but its shape: a mix of a top-five star, a breakout American, and two rising players from Italy and Brazil. It's a lineup built for both today's rankings and tomorrow's headlines.
