How it works

- Once verified and approved, we’ll confirm the matched price and provide a secure payment link.

About grip size
Match the label to the Grip Size options on this page: G2 (4 1/4) means grip size 2 with a 4 1/4-inch handle circumference. Higher G numbers mean larger handles.
| Grip size | Circumference (inches) |
|---|---|
| G1 | 4 1/8 |
| G2 | 4 1/4 |
| G3 | 4 3/8 |
| G4 | 4 1/2 |
Choosing your fit
- Smaller hands: start by comparing G1 or G2. For a fuller handle, compare G3 or G4. These are starting points, not a fixed rule.
- Try the racquet with your usual wrapping. As a starting check, leave about an index finger's width between your fingertips and palm.
- Between sizes? Usually choose the smaller size and build up with an overgrip. A handle that is too large is harder to reduce.
Only the sizes listed in this product's selector are offered for this model. Handle shape also affects fit, so try it in-store if possible.

DUNLOP SX 300 (Teal/Yellow) 300g Tennis Racquet - Unstrung & Free Grip
Dominate the Court with Control & Spin – Welcome to the Spin Generation
The new-mould DUNLOP SX 300 delivers effortless power and heavy spin for intermediate to advanced players. A 100 sq in head, open 16 x 19 pattern and sub-320 swingweight make it quick through the air, while updated Spin Boost XT grommets maximise string snap-back for extra RPMs.
For 2025 the beam face is widened at 3 and 9 o’clock, boosting torsional stability and energy transfer. Comfort is elevated with Vibroshield dampening in the shaft and head, and Sonic Core Infinergy® in the upper hoop adds a softer, more responsive feel on impact. The result is a speedy player’s racquet that lets you attack with confidence, hitting “more in, not just more spin.”
