The Latest Revolution in Tennis is Here: Wilson Triniti Ball

The tennis ball hadn't changed much in 40 years. 

So Wilson Sporting Goods Co. set out to create a tennis ball that wouldn’t need pressurized plastic packaging to maintain liveliness. Wilson LABS, the innovation hub at Wilson, used state-of-the-art materials to redesign the tennis ball core and its felt cover.

The result is Triniti. 

“We see Triniti as a big win for players, the industry, and importantly, our environment,” said Hans-Martin Reh, General Manager, Racquet Sports. “While the tennis ball has not fundamentally changed over 40 years, it has contributed to landfill issues across the world. We decided to re-engineer the ball from the inside out to be gentler on our world while not giving an inch on performance, actually enhancing it.”

Two key features mark the Wilson Triniti tennis ball. The first is the core, which is made of a plastomer material, which weighs less than traditional tennis ball cores and allowed Wilson product engineers to thicken the core’s walls. The ball stays in play longer, provides more control, spin and feel, and maintains its liveliness four times longer than a traditional Wilson tennis ball. 

The second element is the felt. The Triniti ball is covered in STR felt, which is 50% more flexible than conventional tennis ball felt and allows for more compression. The flexible felt also leads to longer dwell times, meaning the player has enhanced feel and control because the ball stays on the racquet’s strings longer.

All of these innovations have allowed Wilson to start the latest revolution in tennis ball technology: a fully recyclable paper canister. The redesigned core and felt combine to keep the air pressure inside the ball, meaning Triniti balls don’t need to be stored in pressurized plastic PET containers to maintain their longevity and performance. Wilson Triniti packaging is made from recycled cardboard. 

Triniti balls are available in three-ball containers for $5.49 (MRP). Five percent of profits from Triniti tennis balls will support Wilson Sporting Goods’ global sustainability efforts.*
