Yonex POLYTOUR REV 17G Tennis String Reel Mint

The Yonex POLYTOUR REV in Mint is a high-intensity co-polyester designed for the modern game, where heavy topspin and a "dropping" ball trajectory are essential. It is widely recognized for its vibrant color and its ability to provide massive spin without the stiff, jarring sensation associated with traditional shaped strings.

Performance Profile

1. Maximum Snapback (SIF Technology): REV features Yonex’s Silicone Oil Infused Filament (SIF) technology. This manufacturing process infuses silicone oil deep into the string’s core, creating an ultra-slick surface that allows the strings to slide and "snap back" with extreme velocity.
2. Aggressive Spin: The string is 8-sided (octagonal). This shaped profile bites into the ball’s felt, while the SIF technology ensures those edges slide freely, resulting in a heavy, high-arcing ball that dives quickly into the court.
3. Predictable Control: Despite its spin potential, the feel is remarkably stable. It offers a firm but not "stiff" response, allowing aggressive hitters to maintain a consistent launch angle even during high-velocity rallies.
4. High Tension Maintenance: It is engineered to hold its playability longer than many other shaped polyesters, preventing the "launchy" or unpredictable feel that occurs when a string loses its tension.
5. Lively 17G Gauge: The 1.20mm (17G) thickness provides increased feel and even more bite than the thicker 16L version, making the racquet feel more responsive and "connected."

Best Suited For

1. Spin-Heavy Baseliners: Players who want to push their opponents back with high-bouncing, heavy topspin shots.
2. Modern Aggressive Players: Those who swing with high racquet head speed and need a string that "tames" their power with rotation.
3. Players Seeking Comfort in Poly: While it is a firm string, the SIF technology makes it feel smoother and more dampened than a standard "dry" shaped polyester.
4. Aesthetic Enthusiasts: The Mint colorway is one of the most unique in the industry, offering a fresh, "pop" aesthetic that pairs beautifully with the Yonex VCORE or EZONE frames.

Key Advantage: The SIF Technology

Most shaped strings lose their spin potential as the strings begin to "notch" (dig into each other). The SIF technology in POLYTOUR REV acts as a permanent lubricant, ensuring that the strings continue to slide and snap back long after other shaped strings have become stuck in place. This ensures that the "spin window" of the string lasts for the duration of the string's life.
