The Yonex VCORE Xi 25 graphite junior tennis racket is 25 (63.5cm) long, which makes it perfectly suited to green zone players aged 9 & above who are 44 to 48 tall. A graphite construction makes the frame lightweight & manoeuvrable to provide competitive junior players with better control & spin that is also enhanced by a 16 x 20 string pattern. The 98in 2 (632.2cm 2) head size of the racket has an extra isometric shape to enlarge an effective hitting area for more match winning shots, whereas a head heavy balance of the racket provides more stability, power, & spin.
