KAP K7 SEVEN HydroGrip Size 4 Water Polo Ball — NCAA/NFHS Official, Yellow/Red, Durable Grip

The KAP K7 SEVEN KAP7 Size 4 HydroGrip is the official NCAA and NFHS-approved women's/high school water polo ball engineered for superior grip, consistent flight, and long-lasting performance.

Built from KAP7's HydroGrip technology and precision-wound construction, this Size 4 ball is designed to meet collegiate and high school match standards while delivering durable playability for practices and tournaments. Its yellow and red colorway improves visibility in the pool, and hand-buffed, water-reactant surfaces create confident handling under wet conditions. Engineered for refereed competition, the HydroGrip combines materials and manufacturing techniques that emphasize control, consistent bounce, and match-ready feel out of the box.

How does the HydroGrip improve handling during matches?

The HydroGrip surface reacts with water to increase tack without relying on stick-on textures, giving players a reliable grip in wet environments. A hand-buffed finish further refines contact feel so passes and shots stay precise even with heavy splashing. The result is better ball control for passing, shooting, and goalkeeper saves.

• Water-reactant grip enhances tack in wet conditions
• Hand-buffed surface for consistent tactile feedback
• Even surface profile reduces unwanted slips on release

Is this ball built to last through regular training and competition?

Yes — the HydroGrip uses a precision-wound nylon carcass that keeps shape, inflation stability, and consistent bounce over time. KAP7's construction methods focus on resilience against pool chemicals and repeated impacts, so teams get more game hours before replacement. Proper inflation and routine care extend the usable life even further.

• Precision-wound nylon carcass for durable shape retention
• Materials selected to resist chlorine and abrasion
• Manufacturing tuned for long-term, consistent performance

Does this meet official size and competition standards?

This Size 4 HydroGrip is officially recognized for NCAA women's play and NFHS high school girls' competition, meeting governing-body specifications for circumference, weight, and performance. Teams and referees can trust the ball for sanctioned matches and tournaments. Always confirm local event requirements before match use.

• Designated as the Official NCAA women's game ball
• NFHS authenticated for high school girls' competition
• Manufactured to match standardized size and weight tolerances

What color and visibility advantages does the yellow/red pattern offer?

The contrasting yellow and red panels improve sightlines for players and officials, especially during fast exchanges and aerial passes. Brighter, two-tone patterns help differentiate the ball against varying pool light and background conditions. This makes it easier to locate the ball quickly in crowded plays and assists in split-second decision-making.

• High-visibility yellow base with red contrast panels
• Improved tracking during fast movement and splashes
• Team-friendly color choice for clear identification

Who is this for: Coaches, competitive women's and high-school teams, club programs, and individual players who need an official, competition-grade Size 4 ball that balances grip, durability, and visibility. It's also suitable for training sessions where match-feel and long lifespan are priorities. Choose the KAP K7 SEVEN KAP7 HydroGrip when you want an NCAA- and NFHS-approved ball that performs reliably across practices and games.
