Boom Jr. Alternate 2026

The HEAD BOOM ALTERNATE JR 26 was developed for ambitious juniors aged 9 to 11 years who want to play modern tennis with power and confidence. Inspired by Coco Gauff, whose favorite color is purple, this racket impresses with a striking tonal purple design that perfectly matches the explosive feel of the BOOM series.

Thanks to the innovative Hy-Bor material in the shaft – a cutting-edge material mix from aerospace engineering – the racket offers improved stability and powerful strokes. The Auxetic 2.0 technology additionally provides a more direct ball feel and precise feedback at the point of impact. Based on the adult rackets BOOM MP and BOOM MP L, this model has been specially adapted to the needs of young players.
