ReString Slap
Characteristics
ReString Slap is a hexagonal co-polyester built around relentless spin and dialed in power.
Its sharp six-sided profile bites into the ball on every stroke, producing high-RPM spin that rewards aggressive cuts.
Our Signature Snapback coating lets the mains and crosses slide and snap back into place quickly between shots, storing and releasing energy for a fast, explosive response.
The result is serious power paired with the forgiveness needed to commit to big shots, even when contact lands off the sweet spot. If you want an even more powerful and lively response, consider ReString Zero, our all-out power and spin string.
ReString Slap shares a similar base formula to ReString Zero and plays as a tamer version of its sibling. The added control and forgiveness do not pull it out of the power category, but they do make the response easier to manage.
It is also engineered for long-lasting playability, holding its fresh feel and tension well past the point where a traditional polyester would start to fade.
ReString Slap originally launched as a limited edition collaboration. The response from players was strong enough that we brought it back as a permanent fixture in the lineup.
It has since drawn praise from third-party reviewers, including Tennis Spin, who called ReString Slap one of his favorite strings we have ever made.
Playing Style
ReString Slap is a strong fit for dominant players, especially aggressive baseliners who hit through the ball and rely on high-RPM spin from a shaped polyester.
All-court players who lean toward power and spin will also find ReString Slap a comfortable match, with enough control built in to stay composed when the rally shifts.
For players who already generate pace naturally, ReString Slap adds spin and bite without overpowering the response. The forgiveness in the stringbed lets you swing freely with confidence.
Availability
ReString Slap comes in two gauges, 17G (1.23mm) and 16G (1.28mm).
You can buy ReString Slap as a 12.2m single set, a bundle of five sets, or a 200m reel.
ReString Vivo
Characteristics
ReString Vivo is ReString's first string crafted from recycled polyester, pushing the boundaries of what a next generation tennis string can be.
Independent testing points to ReString Vivo being the best sustainable string on the market.
For example, Racketpedia recently rated ReString Vivo across the key performance categories. ReString Vivo scored 100/100 for tension holding, 95/100 for spin, and 90/100 for control.
These scores place ReString Vivo among the top performing polyesters on the market, recycled or otherwise.
For further confirmation, Tennisnerd loved ReString Vivo during his testing before we told him it was even a recycled polyester string, not a virgin polyester string.
The hexagonal shape of Vivo is purpose-built to grip the ball, helping you create sharper angles and dipping spin on aggressive groundstrokes.
ReString Vivo does not feature the Signature Snapback coating, but instead features a crisp connection that gives the string a much more direct ball feel at contact.
There is minimal string movement during the strike, translating into a predictable, reliable response shot after shot.
ReString Vivo also plays slightly firmer than other polyesters, contributing to its crisp connection and strong tension maintenance that holds steady over time.
Playing Style
ReString Vivo suits experienced hitters who generate their own pace and want a direct stringbed.
The string is a strong match for all-court players and baseliners who want a balanced response with bite-first spin and precise feedback.
If you build rallies through targeting and shot placement, ReString Vivo gives you the tools to find your spots with confidence.
ReString Vivo is also the natural choice for eco-friendly players who care about sustainability without compromising on performance.
Availability
ReString Vivo comes in two gauges, 17G (1.23mm) and 16G (1.28mm).
You can buy ReString Vivo as a 12.2m single set, a bundle of five sets, or a 200m reel.
Conclusion
ReString Slap and ReString Vivo share a hexagonal shape and a commitment to spin, but they take different paths to performance.
ReString Slap is for players who want explosive spin and snapback with easy access to power, plus the control and forgiveness to keep big shots on the line.
ReString Vivo is for players who want bite-focused spin and a controlled, direct response, with sustainability built into the product from the ground up.
