Introducing the most stable and surgical member of the SX family. It's called the SX 300 Tour, and it combines a control-oriented 98-square-inch head with a dangerous combination of power and spin (think heavy ball). In addition to its open string pattern, the SX 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. Dunlop also updates its Spin Boost XT Grommets, which have been widened in the yoke to increase string movement for greater snapback and added ball rotation. As with the previous version, these grommets are strategically shaped and positioned to enhance spin across a wider range of impact locations. Additional technologies include Sonic Core Infinergy, a thermoplastic polyurethane in the upper hoop, to create a more comfortable and responsive feel at impact. Ultimately, the 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.
