How do I choose the right string for my playing style?

The easiest way to find your match is to visit our discovery page, where you can explore our strings based on your playing preferences.

For a detailed comparison, check out our article What ReString String is Best for You, which breaks down how Zero, Sync, and Vivo perform across different playing styles.

A quick summary is that Zero delivers maximum power and spin. Sync provides excellent control and feel. Vivo offers exceptional control with spin and is our most sustainable option.

Which gauge should I pick?

Thicker gauges (16G for Zero and Vivo, 17G for Sync) provide more durability and power. They're ideal if you break strings frequently or prefer a stiffer response.

Thinner gauges (17G for Zero and Vivo, 18G for Sync) offer better spin potential and feel. The tradeoff is they'll wear out faster, especially for hard hitters.

For more details, read our guide on Tennis String Gauge.

What tension should I string my racket at?

Each of our product pages includes a recommended tension range specific to that string.

We generally recommend stringing 2 lbs lower than your usual polyester setup to maximize the snapback and playability benefits of our strings.

Lower tension provides more power and comfort by allowing the stringbed to flex more. Higher tension gives you more control and a firmer feel but can increase stiffness.

For a deeper dive into how tension affects your game, read our article on Tennis String Tension.

How often should I restring my racket?

A good rule of thumb: restring your racket at least as many times per year as you play per week. If you play three times a week, restring at least three times a year.

You'll know it's time to restring when your stringbed feels less responsive and stiffens up, even if the strings haven't broken yet.

All of our strings are designed for exceptional longevity and tension maintenance, meaning less frequent restringing for you. Zero and Sync achieve this by having a special low-friction coating.

What string material is best for me?

Polyester strings like Zero and Sync, and even recycled polyester strings like Vivo, deliver excellent control, spin potential, and durability. They're the choice of most competitive players.

Multifilament strings offer more comfort but less durability and control than polyesters. They're a good option if arm comfort is your top priority. They also work well in a hybrid with polyesters.

Synthetic gut provides a middle ground between multifilament and polyester with decent comfort and durability at an affordable price. It's only really popular with recreational players.

Natural gut offers the best feel and comfort but is expensive and wears out quickly. Many pros use it in hybrid setups with polyesters, However, the price is simply not worth it for most players.

Do you offer hybrid stringing recommendations?

Yes! Hybrid setups let you combine the characteristics of two different strings to customize your racket's performance to exactly how you want it.

Our most popular hybrid combinations are Zero x Sync (used by WTA pro Cristina Bucsa) and Vivo x Sync. However, you can combine any of our strings to suit your game.

For more, read our articles on how to combine Zero and Sync, Vivo and Sync, and Zero and Vivo.

The most convenient way for you to purchase strings for a hybrid combination is with our Half Set Custom Box. That includes 16 half sets (6.2m), which is enough for 8 rackets.

Are your strings recycled or eco-friendly?

Vivo is made from recycled polyester, making it our most sustainable string option. It delivers exceptional performance while being made from recycled materials.

Zero and Sync are made from virgin polyester but are engineered to play better for longer. This means less frequent restringing, which reduces waste and your overall environmental impact.

We do also up-cycle old Zero and Sync strings into keychains to attach to your tennis bag.

All our strings are packaged in FSC-certified biodegradable paper, and 100% of our carbon emissions are certified offset through our partnership with Carbonfund.

Learn more on our sustainability page about how we work to reduce our environmental impact.

How do you make and dispose of packaging?

Our single set packaging uses FSC-certified recycled paper, eliminating plastic waste entirely, and uses approximately 50% less material than traditional tennis string packaging.

When you're done with the single set packaging, it can return to the earth naturally since it is biodegradable. No microplastics and no centuries of decomposition time.
