Make a bold statement on court with the BOOM ALTERNATE JR.
Designed for ambitious juniors aged 9–11, this racquet delivers explosive, easy power with the touch needed for confident, modern tennis. The tonal purple design—Coco Gauff’s favorite color—matches its fun, high-energy feel, while endorsements from Gauff and Lorenzo Musetti add serious inspiration. Built by HEAD with a construction based on the adult BOOM MP and MP L, the BOOM ALTERNATE JR features junior-friendly dimensions and advanced materials so young players can swing freely, feel confident, and simply enjoy every shot.
