Yonex POLYTOUR REV Tennis String Purple

The Yonex POLYTOUR REV in Purple is a high-performance co-polyester string engineered for the modern game, where spin and consistency are the ultimate weapons. It is widely recognized as one of the most technologically advanced "shaped" strings on the market, famously used by ATP star Hubert Hurkacz.

The POLYTOUR REV is an eight-sided (octagonal) monofilament designed to provide massive "bite" on the ball. What sets it apart from other shaped polys is Yonex’s proprietary SIF Technology (Silicone Oil Infusion). During the manufacturing process, silicone oil is infused deep into the string's core, allowing it to slide against itself with minimal friction. This results in a faster "snap-back" during impact, which significantly boosts spin potential without sacrificing the string's durability.

Performance Profile

1. Spin (10/10): The combination of the octagonal shape and SIF Technology creates a massive amount of rotation. It is designed to help players hit "heavy" balls that dive into the court and jump off the bounce.
2. Control (9/10): While it offers more energy than some dead polys, it remains a control-oriented string. It provides a predictable launch angle, allowing you to target the lines with confidence.
3. Feel (Medium-Firm): It sits in a "sweet spot" of stiffness—not as bone-jarringly stiff as some traditional polys, but firm enough to provide the "crisp" feedback competitive players demand.
4. Tension Maintenance (8/10): Thanks to the high-density manufacturing process, it holds its playability longer than many other shaped strings, which tend to lose their "bite" as the edges round off.

Best Suited For

1. Aggressive Spin Hitters: Players who take big swings from the baseline and want to maximize the "dip" and "kick" of their groundstrokes.
2. Intermediate to Advanced Competitors: Those who have the swing speed to engage the string's "snap-back" mechanism.
3. Players Seeking "Lively" Control: If you find strings like Solinco Confidential too dead, or Luxilon ALU Power too bouncy, POLYTOUR REV offers a perfect middle ground.
4. Aesthetic Customization: The bold purple color is iconic and pairs exceptionally well with the Yonex VCORE or EZONE frames for a striking on-court look.

The SIF Advantage

Most shaped strings eventually "lock" into place as they notch over time, which kills the spin potential. The SIF Technology in the POLYTOUR REV ensures that even as the string wears, the silicone-infused layers continue to facilitate movement, keeping the spin potential high for the entire lifespan of the string job.
