Extra power with enhanced durability

One of GOSEN’s thinnest and most popular models in the Pro Series, the Pro 66 is recommended for serious players. The multi-filament construction ensures that it retains tension and increases its tensile strength. Using the latest in resin technology, the traditional harder feeling string has been refined to increase durability and providing a good balance of power and crisp shots.
