The
pressureless HEAD T.I.P. GREEN is the perfect ball for kids between 9
and 10 years and starter adults about to transition to a full size
court. It is slightly softer, bigger and only 25% slower than a standard
tennis ball and helps the kids to keep their game and strokes under
full control. Developed with trainers and kids, the HEAD T.I.P. GREEN is
perfect for kids and first-timers to learn how to play on the full size
court. The ball is part of HEAD's Tennis Instruction Program (T.I.P.), a
unique approach to help youngsters learn the game right, developed in
cooperation with the International Tennis Federations "Tennis Play and
Stay!" campaign.
