Vivo is the ultimate all-rounder in the ReString family.
It strikes the perfect balance between Zero's aggressive power and Sync's precision control.
But don’t take our word for it. In this article, you will learn what Tennisnerd thought of Vivo and how it could be the string to level up your game.
Vivo Joins ReString Lineup
Vivo, our newest addition to the ReString lineup, launched in 2025.
It delivers a crisp, responsive feel with every shot, providing the perfect balance of control, power, and spin for players who demand consistency across all aspects of their game.
If you are curious about how Vivo compares to our other strings, we recommend checking out our detailed comparison articles on Vivo vs Zero and Vivo vs Sync to find which ReString product best suits your playing style.
Now let’s hear what Tennisnerd thought of Vivo.
What Tennisnerd Thought of Vivo
Note: Jonas from Tennisnerd received samples of Vivo for testing without any payment to ensure his review remained completely unbiased. We simply sent him the strings and allowed him to test them thoroughly at his own pace.
Testing Methodology
Jonas conducted extensive testing of Vivo across multiple rackets to provide a complete performance assessment.
His test rackets included the Babolat Pure Drive 100, Nordicdots Model 100, Babolat Pure Aero 98, and Head Radical MP. This diverse selection allowed him to evaluate Vivo across different frame types and string patterns.
During the testing phase, Jonas worked with prototype versions of Vivo in multiple colors, including purple and dark blue, before we finalized the Aqua color for production.
He experimented with various tension settings ranging from 44 lbs (20 kg) to 53 lbs (24 kg) to understand how the string performs across different setups.
Performance Observations
Jonas reported "astounding" tension maintenance with Vivo.
Even after weeks of play, the string maintained its performance characteristics, something rare among polyester strings. He specifically highlighted the excellent spin potential and control, noting that Vivo has "that dip in at the last second" quality that he highly values in tennis strings.
Jonas was particularly impressed by the string's "bite" on the ball, allowing for aggressive grip during powerful strokes. This characteristic is partly due to the hexagonal shape of the string, which enhances spin potential.
According to Jonas, Vivo offers a "medium firm" feel that strikes an ideal balance. This makes it accessible to a wider range of players with different preferences.
Using his ERT 300 tension measuring device, Jonas confirmed the exceptional tension retention properties of Vivo through objective measurements.
Racket Compatibility
In the Babolat Pure Drive 100, Jonas found Vivo worked "brilliantly" at 53 lbs, complementing the racket's power with added control.
He was pleased to discover the string still provided excellent control and responsiveness when strung at a low 44 lbs in the Nordicdots Model 100.
The Babolat Pure Aero 98 strung with Vivo at 49 lbs showed enhanced spin potential while adding stability to shots.
In the Head Radical MP, Jonas noted the string felt somewhat firm, suggesting it pairs better with more powerful, open-patterned frames.
One interesting insight came from his friend Nikki, who switched to Vivo in his Yonex VCore 98 Tour at just 44 lbs and reported excellent comfort and control.
Expert Comparison
Jonas directly compared Vivo to Head Lynx Tour, one of his all-time favorite strings, noting similar performance characteristics. He also found similarities to Solinco Hyper G, another popular string among advanced players.
According to Jonas, Vivo slots perfectly between ReString's existing offerings (Zero and Sync). This matches our engineering goal of creating the ultimate balanced string.
Perhaps most telling was the reaction of his hitting partner Nikki, who "usually wants to roast any new product" but was surprisingly positive about Vivo.
The final verdict placed Vivo among Jonas's top recommended strings. He doesn't make this statement lightly, considering the number of strings he has tested.
The Sustainable Surprise
When we sent Vivo to Jonas for testing, we deliberately withheld one important detail. Jonas had no idea that Vivo is made from recycled polyester.
We intentionally chose to let the string's performance speak entirely for itself.
We wanted Jonas to evaluate Vivo purely on its playing characteristics without any preconceptions about recycled materials potentially affecting performance. Many players assume that sustainable products might involve compromise, but we designed Vivo to prove this assumption wrong.
The approach worked perfectly. Jonas fell in love with Vivo based solely on how it played, not because of its environmental credentials.
We revealed the sustainable nature of the string only after his initial play testing review. His reaction confirmed what we already knew: recycled materials can produce top-tier performance without compromise.
This validation from such a respected tennis expert is particularly meaningful. It proves that players no longer need to choose between performance and sustainability.
With Vivo, you get both premium playability and environmental responsibility in one package.
Jonas was so impressed by this revelation that he immediately requested more string. This is a testament to Vivo's appeal even to the most knowledgable players.
Conclusion
Tennisnerd's comprehensive testing confirms that Vivo delivers exceptional performance as the balanced all-rounder in the ReString lineup.
Jonas praised its astounding tension maintenance, excellent spin potential, and versatile compatibility across various rackets. Most impressively, he had no idea he was testing a string made from recycled materials, proving that sustainability doesn't require performance compromise.
