Best Tennis Strings of 2026: Our Top 5 New Releases
By Josh, PH Tennis
Quick Summary
Tennis strings are the engine of your racket, and 2026 has had lots of new releases. These are my top five. One important caveat: I could only pick strings that were new this year.
- Solinco Confidential Soft: my number one. More powerful and softer than Hyper-G and the normal Confidential. So popular it has sold out in the UK.
- reString Slap: a slightly more controlled, more dampened-down Zero. It may even surpass Zero.
- Toroline A5: crisp, connected and full of spin. It's what I currently have in my Pure Drive.
- Tecnifibre Razor Spin: the spinniest of the Razor Soft family.
- reString factory hybrid sets: not a new string, but a new setup.
If you haven't tried them, what have you been sleeping on? Especially Slap, especially A5, and especially Confidential Soft.

My Top Five at a Glance
| Rank | String | Best for |
|---|---|---|
| 1 | Solinco Confidential Soft | Poly players who want more comfort, power and forgiveness |
| 2 | reString Slap | Zero fans who want more control and comfort |
| 3 | Toroline A5 | Aggressive, fast swings that like a crisp, connected feel |
| 4 | Tecnifibre Razor Spin | Maximum spin with a connected feel |
| 5 | reString factory hybrid sets | Trying a poly hybrid without cutting two sets yourself |
What This Is
We've had lots of string releases this year from lots of different brands, and we've tested them. These are my five favourites from 2026. For each one I'll explain why it made the list, the types of players who are going to enjoy it, and the types of players who might want to avoid it.
My Verdict
My number one string of 2026 is Solinco's Confidential Soft. It gives Solinco's range a comfort poly answer, with Confidential's great control in a softer, more powerful and more forgiving package.
If you love string and you love new things, these are all the ones you should have tried this year.
My Top Five Strings of 2026
5. reString Factory Hybrid Sets
At number five, it's a bit of a cop-out, and I'm going to get lots of heat in the comments, but I don't care. It's reString's newest release, which came out very recently: the new hybrid sets.
Factory hybrids are becoming a thing. No more buying two reels or two sets and cutting them in half yourself. You can now get a hybrid set all in one pack, half and half, already done. It's so new we haven't had our stock yet.
Toroline have been doing this for a while, with lots of hybrid options and endorsements from influencers putting different strings together. Pretty cool. But reString have done it with Sync as the cross string. That's their round poly: great for control and great for snapback. You can get it paired with Zero, Slap or Vivo.
So if you want to try a hybrid or a blend, because they're both polyester strings, reString's new factory hybrid is the way to go. Not a new string, but a new setup.
4. Tecnifibre Razor Spin
At number four, we have a string from Tecnifibre's Razor Soft family: Razor Spin. As the name suggests, it's a spin string. It's square in shape, so it really bites into the ball. But because of the special polyurethane additive in the string, it's quite comfortable, and softer than you'd expect from this type of poly.
It's certainly the spinniest of the Razor Soft family. Even though the family is called soft, I wouldn't say it's that soft. But if you like that connected feel and you're looking for ultimate spin, Razor Spin is a great new addition, one we thoroughly enjoyed testing, and one you should try too.
3. Toroline A5
Toroline love a string release, and this year was no different. My favourite, and what I currently have in my Pure Drive, is the A5.
Some people found it a little too stiff. Personally, I really like that feel. The feedback is very crisp, and you also generate a lot of spin. To an extent, it's been a bit of a myth-buster, because the A5 is round. Traditionally, people would say a round string wouldn't generate much spin, but this one performs very well. Slick on slick, round on round, generating plenty of spin.
So if spin is what you're after, you have an aggressive, fast racket speed and you like a crisp, connected feel like I do, the A5 is certainly one to try.
If you want a slightly softer version of the A5, there's the Toroline Cash. You still get the feel and the spin, but not quite the harshness of the A5. And to those of you in the comments who say no good players ever actually use strings from Toroline or reString: well, here you go. Cash. Pretty sure he's got some Grand Slams in the bank, even if it is doubles. I just happen to love the A5.
2. reString Slap
At number two, from reString, is Slap. I feel a little wrong putting it in, which is why it's only number two. Slap was first introduced in 2025 as a collab string with Valldoreix, and it was so popular that it's come back as a string in its own right. Slap is here to stay. As I mentioned, you can also get it in the new hybrid pack with Sync.
Zero is probably reString's flagship poly: all about power, spin and snapback, lively, and just a great load of fun on a tennis court. If you want a slightly more controlled, slightly more dampened-down version, where the ball doesn't fly on you as often, Slap is the solution. It also comes in a more neutral colour, so if you don't like the blue, you can get a nice black string.
Slap has been very successful, and I think it will continue to be. It may even surpass Zero, because you get lots of Zero's playability without some of the randomness, and with a lot more comfort and control, without losing its explosive identity.
1. Solinco Confidential Soft
At number one, from Solinco, is the bright pink Confidential Soft. It's so popular it has sold out in the UK. We can't get any more. All we have is a sample set left over, which we had to scramble to find.
Confidential Soft is more powerful and softer than Hyper-G and the normal Confidential. It gives Solinco's range more of a comfort poly answer. You still get the great control you get from Confidential, but softer and more comfortable, with more power and forgiveness. That makes it a more arm-friendly option than Confidential. You still get a great amount of connected feel, and more power than you'd probably expect.
It's certainly a comfort poly, a softer poly, but not a comfort string. If you normally use multifilaments, natural gut or synthetic gut, this isn't a replacement for those. But if you're in the poly range, you like the control, feel and spin you can get from a poly, and you want something a little softer, Confidential Soft is certainly one to look for.
It also helps that it's bright pink, so everyone knows what you've got. If you have a racket that goes well with pink, like a Speed, you're in business.
Who Each String Is For
Solinco Confidential Soft: poly players who like the control, feel and spin of a poly but want something softer, more powerful and more arm-friendly. If you normally use multifilaments, natural gut or synthetic gut, it isn't a replacement for those.
reString Slap: players who love Zero but want a slightly more controlled, more dampened-down version, with more comfort and less randomness.
Toroline A5: players after spin, with an aggressive, fast racket speed, who like a crisp, connected feel. Some find it a little too stiff. If that's you, try the softer Toroline Cash.
Tecnifibre Razor Spin: players looking for ultimate spin who like a connected feel. Despite the Razor Soft name, it isn't that soft.
reString factory hybrid sets: players who want to try a poly hybrid with Sync in the crosses, without buying and cutting two sets themselves.
