Slazenger has been the official supplier of tennis balls for Wimbledon since 1902. Slazenger balls have been used in every Wimbledon tournament since then, with the exception of the years 1915-1918 and 1940-1945, when the tournaments were cancelled due to the First and Second World Wars. Slazenger balls are made with a special woven wool felt which is designed to keep the ball's bounce consistent in all weather conditions.
