HEAD Boom Jr. 25 Alternate Junior Tennis Racquet

The HEAD Boom Jr. 25 Alternate Junior is a premium, high-performance junior frame designed for ambitious young players aged 8 to 10 years (height around 127–141 cm / 50–55.5 inches). Showcasing a striking, limited-edition tonal purple colorway (endorsed on tour by stars like Coco Gauff and Lorenzo Musetti), this racquet offers young competitors an eye-catching alternative to the standard mint green Boom aesthetic.

Weighing 230 grams (unstrung) with a 25-inch length and a 100 square-inch head size, it scales down the geometry of the adult Boom MP frames to give rising players explosive power, effortless handling, and exceptional touch.

Performance Profile

1. Explosive Power & Depth (9.5/10): Superior. Built with HEAD's signature Boom morph-beam profile, it generates effortless ball speed and depth on full-court groundstrokes.
2. Maneuverability (10/10): Exceptional. At an ultra-light 230 g with an even/head-light balance, it swings fluidly through the air, encouraging proper mechanics and fast net setups.
3. Comfort & Shock Absorption (9.0/10): High. Features Auxetic 2.0 technology to absorb impact vibrations and deliver a smooth, connected feel that protects young joints.
4. Spin Access (8.5/10): Natural. The open 16x19 string pattern facilitates main-string movement, making it simple to generate topspin on groundstrokes and kick serves.

Key Technologies

1. Auxetic 2.0 Technology: Integrated into the yoke and handle to optimize tactile feedback, offering dynamic flexibility and dynamic connection with the ball.
2. Hy-Bor Construction: Incorporates a high-tech aerospace material mix in the shaft to enhance frame stability and provide a solid impact feel.
3. Full Graphite Composition: Premium graphite build ensures true energy transfer, frame longevity, and feel over basic aluminum junior racquets.
4. Graphene Inside: Strategically positioned along the hoop to reinforce structural frame stability and power delivery.

Best Suited For

1. Ambitious Juniors (Ages 8–10): Rising young players who want an explosive, power-focused performance frame built for full-court play.
2. Green Ball (Stage 1) & Yellow Ball Hitters: Juniors stepping up from 23-inch frames to learn competitive stroke mechanics on full-size courts.
3. Coco Gauff & Boom Fans: Young players seeking the unique tonal purple styling endorsed by tour pros.
