Dunlop SX 300 Tour 2025

Introducing the most stable and surgical member of the Dunlop SX family. It’s called the Dunlop SX 300 Tour, and it combines a control-oriented 98-square-inch head with a dangerous combination of power and spin. In addition to its open string pattern, the SX 300 Tour features a firm and stable beam construction, making it easier to keep your opponent in check with high levels of pace. It also features a sub-325 swingweight, giving experienced players explosive acceleration from the baseline and speedy handling at net.
For 2025, Dunlop widens the beam’s face at 3 and 9 o’clock to increase torsional stability and energy transfer. To help with comfort, Dunlop adds Vibroshield technology, a dampening material positioned in the shaft and head to minimize harsh impact vibrations. Additional technologies include Sonic Core Infinergy, a thermoplastic polyurethane in the upper hoop, to create a more comfortable and responsive feel at impact.
Ultimately, with some nice updates to the feel and response, the Dunlop SX 300 Tour continues to be an outstanding option for those who want a powerful weapon with enough spin potential to bring the ball down on a dime.
