Yonex Poly Tour Pro is one of the most popular co-poly strings on the market — known for its smooth feel, solid spin potential, and predictable control. Favoured by professionals like Ben Shelton and Naomi Osaka, it’s a go-to for players who want dependable performance without excessive stiffness. Though not the liveliest string, it provides a consistent and comfortable response that suits a broad range of playing styles.
Quick verdict
Yonex Poly Tour Pro delivers that signature smooth feel and controlled spin response that makes it a favourite among club and competitive players alike. It’s comfortable for a poly, consistent through contact, and easy to trust on full swings — but tension loss hits quickly, so it’s best suited to players who restring often or don’t mind a livelier response after a few sessions.
What the numbers and lab tests say
Yonex Poly Tour Pro – Based on independent test data:
| Attribute | Score (%) | Summary |
|---|---|---|

| Resilience Peak | 70% | Smooth rebound and slightly dampened feedback. |
| Elasticity | 50% | Low stretch; maintains control-oriented character. |
| Spin | 95% | Excellent spin generation from slick surface and snap-back. |
| Control | 95% | Impressive precision and directional consistency. |
| Tension Holding | 70% | Drops tension sharply after the first few hours, then levels off. |
| Stability | 65% | Solid until tension drop occurs — then response becomes looser. |
| Comfort | 65% | Soft enough for a poly, especially in thinner gauges. |
How it plays (feel, spin, power, control)
Yonex Poly Tour Pro offers one of the most balanced and predictable playing experiences in the polyester world. The feel is buttery-smooth on impact — firm enough for feedback, yet comfortable compared to stiffer control strings. Spin generation is effortless thanks to its slick surface, which allows the mains to snap back consistently and add bite without feeling harsh.
Power sits in the moderate range, giving depth when you accelerate through the ball but never feeling overpowered. Control is where this string shines — it rewards confident, full swings with reliable trajectory and pinpoint placement. Overall, it’s a string that feels composed and fluid, ideal for baseline hitters who want precision without sacrificing comfort.
Durability & tension maintenance
While Poly Tour Pro offers decent durability for its gauge, its biggest drawback is tension loss — it doesn’t degrade gradually like many polys. Instead, tension can drop noticeably after the first few hours of play, leaving the stringbed feeling looser and less precise. Frequent restringing (every 8–10 hours of play) is recommended if you want to maintain consistent control and feel.

Who it suits
Best For:
- Aggressive baseline players who generate their own pace and want maximal spin + control.
- Individuals with arm concerns who still want tour-level poly performance — Razor Code Soft offers better comfort.
- Accurate hitters needing long tension life for repeated sessions and reliable stringbed response.
Not For:
- Beginners or players with slow swing speeds, who would benefit more from hybrids or softer multis.
- Those seeking plush “gut-like” cushioning — this string still retains a firm poly character.
- Casual players who get minimal restring volume and value immediate comfort over durability.
Best suited racquets
Poly Tour Pro pairs perfectly with spin-friendly and powerful frames, giving them a smoother, more connected response. It also tames stiff, open-pattern racquets by softening impact and enhancing comfort without losing feedback.
| Racquet | Why It Works | Recommended Tension |
|---|---|---|
| Babolat Pure Aero 100 | Adds comfort and control to this powerful, spin-heavy frame. | 22–24 kg (48–53 lbs) |
| Yonex Ezone 100 | Tames power while maintaining great feel and response. | 23–25 kg (50–55 lbs) |
| Head Speed MP | Enhances spin and comfort in a balanced, all-court setup. | 22–24 kg (48–53 lbs) |
| Wilson Blade 98 | Provides a softer, more forgiving poly feel for Blade users. | 21–23 kg (46–51 lbs) |
Comparable strings
Players considering Yonex Poly Tour Pro might also look at:
- String Project Sirius 1.25 — more feel and slightly better tension stability.
- Head Hawk 1.25 — firmer and more control-oriented for flatter hitters.
- Genesis Hexonic 2.0 — A hex-shaped poly celebrated for very good tension-keeping and a crisp yet forgiving response; a solid alternative for durability-minded hitters.
Practible recommendations
Tension Range: 21–23kg (46–51lbs) for optimal blend of control and pocketing. Go lower for more power and comfort, or slightly higher to tighten launch angles.
Hybrid Setup: Pair with a soft cross such as Tecnifibre Multifeel or String Project Sirius to boost feel and maintain control as tension fades.
Player Level: Ideal for intermediate to advanced players who want a comfortable, predictable poly that doesn’t feel harsh or jarring.
Restringing Frequency: Every 10–14 hours of play for consistent performance — tension loss happens fast, so frequent restringing keeps it fresh.
