Featuring a new mold and enhanced dampening, the 2025 SX 300 is a gift to those who want easy access to power and spin. In addition to being light enough for a wide range of intermediates, the SX 300 will also tempt the more advanced ball striker who wants raw speed or a platform for customization. Like the outgoing model, this update combines spin-friendly targeting from the baseline with quick handling at the 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.
