The Dunlop ATP Regular Duty is the 2026 solution for players who prefer the 'Red Dirt' or slow indoor courts. The 'Regular Duty' designation is vital to understand: unlike the fuzzy, thick felt of an Extra Duty ball, this model uses a thinner, more tightly woven felt designed to repel clay particles. On a clay court, a standard ball acts like a sponge, soaking up moisture and dust which makes it heavy and sluggish. The ATP Regular Duty's felt is treated to be naturally hydrophobic, ensuring the ball stays light and fast throughout a grueling clay-court set. This ball is also the preferred choice for indoor carpet or hardwood courts, where the lack of abrasive grit means a thicker felt is unnecessary and would only serve to slow the game down. The internal core is calibrated to compensate for the slower nature of clay, offering a 'lively' bounce that helps the ball clear the net even after multiple long rallies. In the 2026 market, this ball is often purchased by 'flat hitters' who want to maximize their ball speed on surfaces that naturally favor defenders. It should be noted, however, that using this ball on an outdoor hard court is not recommended; the thinner felt will wear down to the rubber core in less than an hour of play. When used on its intended surface, it provides a 'clean' contact sensation and exceptional visibility. For coaches in Europe or the Southern US who deal primarily with clay, the multi-can packs of the ATP Regular Duty offer the highest performance-to-price ratio in the industry. It is the ball of choice for those who value the 'classic' tennis feel where the ball zips through the air with minimal aerodynamic resistance.

You can, but the felt will wear out very quickly (often in less than one set) because it is thinner than Extra Duty felt.
The tight weave prevents clay dust from getting trapped in the fibers, keeping the ball light and consistent.
They often feel 'livelier' on clay because they don't get weighed down by dirt and moisture.
While not the 'Official' ball of Roland Garros, they use nearly identical technology and felt grade for clay court performance.
