Penn Championship Extra Duty
The Penn Championship Extra Duty is the 'standard' against which all North American club balls are measured in 2026. Its defining characteristic is the interlocked wool fiber construction, which provides a predictable nap and a firm, lively bounce straight out of the can. The Extra Duty felt is specifically reinforced with a higher nylon content to withstand the friction of gritty hard courts without balding prematurely. While it is the #1 selling ball for USTA league play, technical feedback in 2026 notes that it prioritizes initial liveliness over long-term pressure retention. It is widely considered a 'one-match' ball—perfect for a high-intensity 2-hour session, but notably less bouncy if left in a bag for a week after opening. It offers a reliable, 'crisp' feel that most intermediate players prefer for serving and flat hitting.
