Dunlop SX 300 2025

Featuring a new mold and enhanced dampening, the 2025 Dunlop 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. Additional technologies include Sonic Core Infinergy, a thermoplastic polyurethane in the upper hoop, to create a more comfortable and responsive feel at impact.
With some impressive tweaks to the feel and response, the 2025 SX 300 remains a great option for those who want a speedy player’s racquet with easy access to power and spin.
