Head BOOM Junior 26" Tennis Racquet (2026)

New for 2026, the Head BOOM Junior 26" Tennis Racquet is built for ambitious players aged 9–11 who want explosive power, confidence and plenty of fun on court.

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.

Explosive power is combined with the touch to play delicate drop shots in the BOOM JR. Ambitious juniors aged from 9 to 11 can play modern tennis with a racquet that has been  
enhanced with the introduction of Hy-Bor, a state-of-the-art material mix that is mainly used in the high-tech aerospace industry. Adding that material to the shaft has improved the racquet’s perceived stability and power. Endorsed by Coco Gauff and Lorenzo Musetti, this model has a construction that is based on the adult racquets BOOM MP L and BOOM MP, with smaller dimensions to suit up-and-coming juniors. With the power, confidence and fun that comes from playing with the BOOM JR, juniors don't have to think about anything else but enjoying the moment and hitting their next shot. Like the adult BOOM frames, the BOOM JR comes in a vibrant blue design inspired by HEAD’s iconic ski racing collection. This racquet will help kids to feel good about themselves and their tennis.
