HEAD Boom Jr.25 Junior Tennis Racquet

The HEAD Boom Jr. 25 Junior is a high-performance frame engineered for ambitious young players aged 8 to 10 years (height around 127–141 cm / 50–55.5 inches) who want explosive power and enhanced tactile feel. Finished in the signature mint green and dark teal cosmetic of the adult Boom series, this racquet scales down adult tour features into a lightweight, age-appropriate size.

Weighing 230 grams (unstrung) with a 25-inch length and a 100 square-inch head size, it features HEAD's unique Morph Beam frame geometry, combining optimal power and stability with high maneuverability for Green Stage (Stage 1) or yellow tennis balls.

Performance Profile

1. Explosive Power & Depth (9.5/10): Superior. The Morph Beam geometry creates a springboard effect, enabling rising players to generate effortless ball speed and depth.
2. Maneuverability (10/10): Exceptional. At an ultra-light 230 g with an even balance, it swings fast and freely through the contact zone, encouraging full stroke mechanics.
3. Impact Comfort & Touch (9.0/10): High. Incorporates Auxetic technology to absorb frame shock, delivering smooth vibration dampening and solid impact feedback to protect young joints.
4. Spin Access (8.5/10): Natural. The open 16x19 string pattern facilitates main-string snap-back, making it simple to generate topspin on groundstrokes.

Key Technologies

1. Auxetic Technology: Integrated into the frame to actively adapt under contact pressure, optimizing tactile feedback and ball connection on every stroke.
2. Morph Beam Frame Geometry: Blends a box beam shaft for control and feel with a powerful metallic head profile for explosive energy transfer.
3. Full Graphite Composition: High-grade carbon fiber construction ensures energy efficiency, structural integrity, and durability over composite junior frames.
4. Graphene Inside: Positioned in key areas of the hoop to reinforce frame stability and power delivery.

Best Suited For

1. Rising Junior Competitors (Ages 8–10): Children standing between 127 cm and 141 cm tall who are building aggressive baseline game styles.
2. Green Ball (Stage 1) & Yellow Ball Hitters: Youngsters stepping up from 23-inch frames to learn full-court rally and match skills.
3. Boom Series Enthusiasts: Junior players looking to match the signature mint green style of HEAD's tour-level Boom frames.
