Head BOOM Junior 26" Alternate Tennis Racquet (2026)

New for 2026, the Head BOOM Junior 26" Alternate Tennis Racquet is built for ambitious players aged 9–11 who want explosive power, confidence and plenty of fun on court. This Alternate version showcases Coco Gauff's favourite colour, purple!

Inspired by the adult BOOM MP and BOOM MP L models, this junior frame features smaller dimensions to suit developing players while still delivering modern performance. Weighing just 245g unstrung, with a 100 sq. in. head and 16x19 string pattern, it offers easy access to power and spin, helping young players hit with depth while still executing touch shots and controlled rallies.

The introduction of Hy-Bor technology, a high-performance material mix used in aerospace, enhances perceived stability and creates a more solid impact feel. Auxetic 2.0 construction provides improved feedback and a more connected response, while Graphene Inside strengthens the frame and optimises energy transfer from racquet to ball.

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.
