Description Robin Soderling Pro Edition Tennis Ball (Dozen) The RS Pro Edition is made for high performance tennis on all types of surfaces. The ball has a special extra duty felt that gives you maximum durability, yet the iconic RS premium feel. The felt is an extra duty woven felt, used in many Grand Slam tournaments, over the years. The ball is slightly harder than the RS Black Edition and RS Tour Edition as it was Robin’s goal to make the ball extra durable.
