Dunlop SX 300 LS 2025

The Dunlop SX series has been upgraded with advanced technologies and a refreshed cosmetic design; this 300 LS variant is suitable for a wide variety of players including capable beginners, intermediate and advanced players who prefer a little less weight.

With a 100-square-inch head, this racquet strikes a balance between control and power while still feeling forgiving on off-centre hits. The open string pattern adds liveliness, making it easier to generate spin. Weighing in at 10.1 ounces (unstrung), it’s slightly lighter than average—light enough for easy movement at the net and quick returns, yet stable enough to handle serves and deliver solid power. Its head-light balance helps you swing the racquet faster, which boosts both spin potential and reaction speed for volleys. The thicker beam design improves frame stability and energy transfer across the string bed, a hallmark of modern 100-inch racquets built for spin and power.

The SX series features advanced technologies designed to enhance performance. The Spin Boost XT Grommet Technology increases grommet hole size by 58% at the 6 o’clock position, allowing greater string movement for improved spin, working alongside angled grommets at the 12 o’clock position for better control. The Spin Boost Frame Geometry increases frame width by 8% at the 3 and 9 o’clock positions, minimizing frame rotation for greater stability, while enhanced stiffness in the face and throat reduces deformation, boosting ball speed and spin. Additionally, Vibroshield Technology, a highly elastic material placed at key points, reduces frame vibrations by 30%, ensuring enhanced comfort during play.

Combined with its core technologies, enhancements, and specifications, this racquet becomes a formidable tool for players seeking to maximise power and spin.

Photos used contain images of strings for illustration purposes. Adult tennis racquets are unstrung unless otherwise noted or stringing services have been selected above. Brand logo stencils are not applied by default with stringing services. If you request brand logo stencils, please note that a stencil is painted onto the strings within a brand's stencil and may wear off over time - this is how stencils are applied on tour. Depending on the string you select, the stencil paint application fullness, colour and visibility may vary.
Adult racquets generally do not come with covers. To protect your racquet, we recommend getting a racquet bag.

Product specs such as weight may vary slightly from racquet to racquet to what is advertised due to the manufacturing process.
