Boom Alternate 2026

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. With the power, confidence and fun that comes from playing with the Boom Alternate JR, juniors don't have to think about anything else but enjoying the moment and hitting their next shot.
