KAP K7 SEVEN HydroGrip Size 4 Water Polo Ball, Yellow/Navy — Official NCAA game ball with superior wet grip

The KAP7 Size 4 HydroGrip is the official NCAA women's and high school girls' water polo game ball engineered for superior wet-condition grip and tournament-grade durability.

Built from KAP7's proprietary HydroGrip material and precision-wound core, this Size 4 ball combines dependable feel with competition-ready construction. Designed to meet NFHS and NCAA requirements, the HydroGrip is crafted for game use at local leagues, high school championships, and collegiate competition where consistent handling and long wear matter.

How does the HydroGrip improve handling in wet play?

The HydroGrip compound is formulated to react with water so the surface becomes tackier during play, giving players more confident passes, shots, and catches. Additionally, each ball is hand-buffed to refine the texture and eliminate manufacturing inconsistencies that can affect grip.

• Water-reactive surface increases tack when wet for controlled handling
• Hand-buffed finish smooths the feel and reduces slippage
• Size 4 circumference tailored for women and girls for better control

What construction makes this ball durable for repeated competition?

KAP7 combines a precision-wound nylon carcass with high-quality outer materials to resist deformation and maintain roundness after intensive play. The internal winding and consistent bladder support stable flight and predictable bounce, so the ball stays reliable through seasons.

• Precision-wound nylon carcass for sustained shape retention
• Reinforced bladder for stable air pressure and fewer re-inflations
• Durable outer layer resists abrasion from pool edges and frequent handling

Is this ball approved for organized competition and certified by authorities?

What color options and visibility features does it provide?
