Description
The Yonex Poly Tour Pro is one of the most respected polyester strings on the professional tennis tour — used by ATP and WTA players including Casper Ruud, Jasmine Paolini, and Ben Shelton. This 12m set in Flash Yellow (1.30mm / 16 gauge) is cut from reel and provides enough length for a complete racket stringing.
Made in Japan with co-polyester monofilament construction, the string delivers a uniquely soft feel for a polyester while maintaining excellent durability and spin potential.
What makes this string stand out from other polyester options is its comfort-to-performance ratio. Most poly strings sacrifice arm comfort for durability and spin. The Yonex Poly Tour Pro tennis string achieves both — giving you a soft string bed that reduces shoulder and elbow fatigue while still generating the control and spin that competitive players demand.
SIF TECHNOLOGY ON THE YONEX POLY TOUR PRO
Silicone Oil Infused Filament for Enhanced Snapback
The Yonex Poly Tour Pro features SIF (Silicone Oil Infused Filament) technology — a manufacturing process that infuses silicone oil into the polyester filament during production. This reduces inter-string friction, allowing the main strings to snap back to position faster after contact with the ball. Faster snapback translates to more spin generation on every groundstroke, serve, and slice.
For players in India who play on hard courts — the most common surface across Delhi, Mumbai, Bengaluru, and Chennai — SIF technology helps generate the topspin needed to control the ball on a faster surface. The Yonex Poly Tour Pro 130 gauge with SIF delivers spin levels that rival thinner shaped polyester strings while offering significantly better durability and tension maintenance.
1.30MM GAUGE — THE DURABILITY ADVANTAGE
Thicker Gauge for Extended String Life
This Yonex Poly Tour Pro set comes in the 1.30mm (16 gauge) thickness — the thicker option compared to the popular 1.25mm (16L gauge) version. The 1.30mm gauge offers noticeably longer string life before breaking, making it the better choice for players who hit with heavy topspin, string breakers, and anyone who wants to reduce restringing frequency.
The trade-off with the thicker 1.30mm gauge is slightly less raw power and feel compared to 1.25mm — but the co-polyester construction compensates with its inherently soft design. Many players find the 1.30mm version feels softer and more comfortable than competing polyester strings at the thinner 1.25mm gauge. For a polyester tennis string India players use regularly, the 1.30mm gauge delivers the best balance of performance and longevity.
SOFT FEEL AND ARM-FRIENDLY COMFORT
This string is consistently rated as one of the softest polyester options available. Unlike stiff poly strings that transmit harsh vibrations to the elbow and shoulder, the Poly Tour Pro creates a soft string bed that absorbs impact and reduces fatigue during extended play sessions.
This arm-friendly characteristic makes the string particularly suitable for players who have experienced tennis elbow or shoulder discomfort with stiffer polyester options. You get the control and durability benefits of a polyester string without the punishing stiffness. For competitive players in Pune, Hyderabad, Kolkata, and across India who train daily and cannot afford arm injuries, this comfort advantage is a significant factor in string selection.
SPIN AND CONTROL FOR ALL SWING SPEEDS
The Yonex Poly Tour Pro is engineered for players of all swing speeds — from aggressive baseliners who swing big to all-court players who rely on placement and variety. SIF technology enhances string movement for spin generation, while the co-polyester construction provides a controlled response that keeps the ball inside the lines even on full swings.
This tennis string for spin and control works exceptionally well for heavy topspin groundstrokes, kick serves, and slice backhands. The string bed provides excellent ball pocketing — the ball sits on the strings slightly longer at contact, giving you more directional control and spin information. Whether you string at high tension for control or lower tension for power, this co-polyester adapts to your setup.
FLASH YELLOW COLOR — CUT FROM REEL
This set comes in Flash Yellow — a bright, vibrant color that stands out on any racket frame. The 12m length is cut from reel, which is the standard length needed for a single full racket stringing (mains and crosses). The string arrives unpackaged as a cut set, not in individual retail packaging.
Yonex tennis string quality from reel cuts is identical to individually packaged sets — the same Made in Japan co-polyester monofilament construction, the same SIF technology, and the same performance characteristics. Reel cuts simply offer better value per set compared to individually packaged strings, making the Yonex Poly Tour Pro more accessible for regular restringing.
