Core features and highlights
The Longsail Foam Waterproof Soccer Ball is a durable, all-weather training ball designed for players of all ages and skill levels. Its seamless foam rubber construction provides superior waterproofing, shock absorption, and a consistent touch, making it perfect for rigorous training sessions, casual play, and competitive matches on any surface, including grass, turf, and even beaches.
Seamless, waterproof foam rubber shell ensures the ball does not absorb water, swell, or become waterlogged, maintaining stable performance in wet conditions.
Advanced air-retention technology with a custom double-layer valve minimizes air leakage (less than 1-3% in 48 hours) for reliable play and reduced need for frequent inflation.
Exceptional durability withstands high-impact play, tested to maintain air pressure after 3,000 consecutive impacts at 50km/h.
Eco-friendly and cost-effective manufacturing process produces less pollution compared to traditional leather balls, offering great value.
Complete kit includes the soccer ball, an inflation pin, an air pump, and a convenient drawstring mesh storage bag.
