History & Heritage | Tretorn World


Tretorn has consistently pushed the boundaries of
tennis ball technology since we first began production
of tennis balls in 1902. From the introduction of
patented PRESSURELESS technology in 1955 to the
introduction of MICRO CELL technology in 1998 to the
3-piece pressurized ball construction in 2002, Tretorn
tennis balls remain state of the art. Our new SERIE+ ball is
the favorite of professional tournaments such as the ATP
Challenger Tour and ATP in Stockholm, Hamburg, Zagreb, and
Umag. Pros in training will appreciate our Academy collection,
which includes low compression balls for faster learning.


Our pressurized Tri-Tec tennis balls are the world’s first 3-piece, multi-layer construction tennis balls. A sealing membrane between the core and felt helps maintain the ball’s pressure and performance, providing ultimate durability for unparalleled performance consistency. These balls are recommended for shorter contact time and higher speed play.

Micro Cell

The secret to our Micro Cell tennis balls lies within the patented inner core. 700 million air-filled micro cells means the ball will not lose bounce or performance over time. A highly playable ball, Tretorn micro cell balls are equally suited for the frequent competition player or the occasional recreational player.


In 1955 Tretorn changed the history of tennis as we introduced and patented permanent pressure or ‘pressureless’ tennis balls. Today, Tretorn pressureless balls are the most advanced and playable in the world. Engineeered with Tretorn’s exclusive rubber core formula, our pressureless balls provide the player with a superior combination of playability and durability.


Our motto is ‘slower is faster’, meaning slower balls result in faster learning. The Tretorn Academy range of tennis balls offer options for all stages of skill development. They are softer and lighter than standard balls, resulting in reduced play speed. From oversized, to low and mid-compression balls, to foam balls, Tretorn Academy balls are ideal for beginners ages 4 to 10.
