Yonex POLYTOUR SPIN G is designed for players seeking heavy spin, precise control, and confidence on full swings. Its pentagonal profile grips the ball to help aggressive shots dip sharply into the court, while Silicone Oil Infused Filament (SIF) technology enhances string movement and snapback. The firm, low-powered response allows players to take bigger cuts without sacrificing control. Pre-stretched under carefully controlled temperatures, POLYTOUR SPIN G also delivers improved durability and longer-lasting tension maintenance.
