With added technologies for 2025, the Dunlop SX 300 LS will give players greater access to spin and power. This lighter version of the SX 300 provides very good maneuverability and easy handling. Perfect for intermediate and low advanced players who are looking for a racket with a lighter weight to achieve fast hits with a high spin level.

SONIC CORE WITH INFINERGY – Allows players to hit hard with increased rebound and decreased vibration. We call it controlled power. Sonic Core, located on both sides of the racket head, provides superior rebound and up to 37% reduced vibration.

SPIN BOOST XT GROMMETS – A dynamic set of spin-enhancing grommets at the top of the racket, work with the spin boost string tech pattern to offer more spin, power and control. They allow more string movement in the direction of the arrows shown on the racket. This movement helps generate more spin. The extra movement makes the string bed more forgiving, effectively enlarging the sweet spot.

SPIN BOOST STRING TECH –The string grid area has been increased by 22% by making the main strings 10% wider and the cross strings 11% wider. This results in greater string movement allowing more power and spin generation.

SPIN BOOST FRAME GEOMETRY – Increases the level of power with increased racket stability, and a new Vibroshield dampening material. The changes come thanks to the new geometrys mold and stiffness. The updated frame stiffness in the throat and face allows for increased stiffness by 3% and 7%, respectively

VIBROSHIELD –The high elasticity properties of the vibration dampening material within the racket frame reduce vibrations and gives an increased feeling of control when hitting.

V-ENERGY SHAFT –A unique V shape frame geometry in the shaft area of the racket, greatly enhances frame stability and racket power.
