Product description

Purple is Coco Gauff's favorite color and the tonal purple design of the BOOM ALTERNATE JR – which is endorsed by Gauff and Lorenzo Musetti – offers a striking and progressive look that matches the racquet's explosive feel. Ambitious juniors aged from 9 to 11 can make a powerful statement with a racquet that combines explosive power with the touch to play delicate drop shots, letting them play modern tennis. The introduction of Hy-Bor, a state-of-the-art material mix that is mainly used in the high-tech aerospace industry, to the racquet's shaft has improved the perceived stability and power. This model has a construction that is based on the adult MP and MP L racquets in the BOOM series, with smaller dimensions to suit up-and-coming juniors.

  • Explosive power for ambitious juniors from 9 to 11
  • Hy-Bor enhances perceived stability and the solid impact feel
  • Auxetic 2.0 technology for a more connected feel to the ball
  • Construction based on the adult models BOOM MP L and BOOM MP
  • Endorsed by Coco Gauff and Lorenzo Musetti
