Dunlop
SX 300 (2023)
The SX 300 is Dunlop's spin-focused counterpart to the FX 500 — a stiffer, more aggressive 100 sq in frame designed specifically for topspin players. The Spin Boost Grommets increase string deflection for added bite, while the stiff layup launches the ball with power and depth. Think Pure Aero territory at a lower price point.

Ratings breakdown
Who is this for?
Best for
Intermediate-to-advanced topspin baseliners who want Pure Aero performance at a lower cost
Not ideal for
Players with arm sensitivity or those who want a softer, more controlled feel
Our review
A legitimate Pure Aero alternative at a lower price. High spin, firm feel, and solid power — just be aware it's a stiff frame and not forgiving on the arm.
Editorial note
The SX 300 is essentially Dunlop's answer to the Pure Aero — a dedicated spin weapon at a friendlier price. If you like the idea of the Pure Aero but want to save $50, this is worth a serious look.
