The SX 300 is lightweight enough for a variety of intermediate players, but it will also appeal to more experienced players seeking unadulterated speed or a weapon they can personalize. This version, like the prior model, combines fast handling at the net with strong access to spin from the baseline. Dunlop enlarges the frame's center in 2025 to improve energy transmission and torsional stability. The Vibroshield technology, which reduces the intense vibrations from contact by placing a cushioning material in the head and in the center of the racket, has also been introduced to increase comfort.
