The Slazenger Wimbledon tennis ball is specifically designed for the Wimbledon tennis tournament. The balls are made using the finest wool blend to create a durable fabric, and they are dyed with a special Ultra Vis dye, which ensures optimal visibility for both players and spectators with its bright yellow hue. Slazenger tennis balls have been used on the All England Club’s grass courts since 1902. Although the ball was originally designed for genuine grass, it is also perfectly suitable for all possible surfaces.
