The pressure-free HEAD TIP ORANGE is the perfect ball for kids ages 8 and 9 who are about to make the transition to the bigger court. It is softer, larger and 50% slower than a standard tennis ball, which increases reaction time and makes hitting the ball much easier. Additionally, its two-tone orange and yellow felt makes the ball easier for children to see. Developed with coaches and children, the HEAD TIP ORANGE is perfect for the ITF orange half court (18m x 5.6-8.23m). The ball is part of HEAD's Tennis Instruction Program (TIP), a unique approach to helping young people learn the game well, developed in cooperation with the International Tennis Federations "Tennis Play and Stay!"
