Solinco Outlast is a round co-polyester tennis string designed for durability, tension stability and all-court control. It is one of Solinco’s value-oriented monofilaments and occupies a smoother, less spin-specialized position than Tour Bite, Hyper-G or Revolution.
The name accurately describes its primary purpose, but durability needs context. Outlast can resist breakage and hold a useful response well for polyester, yet it still loses tension and elasticity over time.
It targets strong intermediates and advanced players who want a durable, predictable string without aggressive edges. The Tennis String Finder can help compare it with softer materials.

Material and Construction
Outlast uses a single co-polyester filament formulated for resistance and consistent playability. The complete chemical recipe is proprietary.
The cross-section is round and the exterior is smooth. This produces a uniform response for flat drives, volleys and serves while reducing edge-related abrasion in hybrids.
Solinco now associates Outlast with TruTension, its tension-maintenance positioning. The company claims unusually long co-polyester stability, but the exact testing protocol is not published on the product page.
The absence of sharp edges does not eliminate spin. The smooth mains can slide and return across the crosses, creating rotation through snapback and technique.
Solinco Outlast Performance
Power
Outlast provides controlled, medium-low power. It offers slightly more response than the most rigid traditional polyester but still expects the player to create pace.
The thin 1.20mm and 1.15mm versions add pocketing and easier depth. The 1.30mm version creates the most restrained launch.
Manufacturer high-power language should remain in polyester context. Multifilament and natural gut supply much easier rebound for compact strokes.
Power rating: 6/10
Spin
Outlast offers good spin for a round co-polyester. Its smooth surface supports string movement, while the controlled response lets developed players accelerate upward.
It lacks the direct edge-assisted bite of Tour Bite or Revolution. Players seeking maximum geometric spin should choose a shaped Solinco string.
Thinner gauges improve ball interaction and snapback access. Spin declines when the intersections notch and the mains remain displaced.
Spin rating: 8/10
Control
Control is a clear Outlast strength. Its moderate power and uniform profile produce a predictable trajectory across baseline, transition and net play.
Flatter hitters may appreciate the round response more than an aggressively shaped string. Heavy topspin players can still use snapback without accepting a high shaped-string launch.
Control changes as tension and elasticity decline. A visually intact string should be replaced if balls begin launching unpredictably or the impact becomes rigid.
Control rating: 8.5/10
Comfort and Feel
Outlast has reasonable comfort for a durability-focused co-polyester. Retailer evaluation often describes it as softer than traditional polyester, with a crisp but playable response.
It is not soft across the wider market. A thick full bed in a stiff racket can still feel demanding, particularly on off-center contact.
Players with current arm sensitivity should choose multifilament or natural gut rather than relying on comparative polyester comfort.
Comfort rating: 6.5/10
Durability and Tension Maintenance
Physical resistance is Outlast’s strongest construction benefit. The round profile and co-polyester material resist notching and breakage, especially in 1.30mm and 1.25mm.
Solinco describes Outlast as one of the biggest TruTension beneficiaries and claims exceptional co-polyester tension maintenance. Independent standardized data is limited, so this should remain an attributed claim rather than a universal fact.
Useful playability is separate from breakage. Replace Outlast when snapback, comfort or control declines, even if the string remains unbroken.
Choosing the Right Gauge
| Gauge | General characteristics |
|---|---|
| 16 / 1.30mm | Maximum resistance, stability and controlled launch |
| 16L / 1.25mm | Balanced durability, control and response |
| 17 / 1.20mm | More pocketing and spin access |
| 18 / 1.15mm | Most responsive and least physically durable |
The 16L / 1.25mm version is the best general starting point. Frequent breakers may prefer 1.30mm, while dense patterns can benefit from 1.20mm.
Full Bed or Hybrid Setup
Full Bed
A full bed maximizes Outlast’s durability and uniform control. It suits experienced polyester users who want a practical, value-focused setup.
Players who do not break nylon strings have less reason to accept the reduction in power and comfort.
Solinco Outlast in the Mains With Softer Crosses
Outlast mains preserve control and resistance, while natural gut, multifilament or synthetic-gut crosses add pocketing.
Its round profile is less abrasive than shaped mains, although it will still notch a soft cross through normal movement.
Softer or Shaped Mains With Solinco Outlast Crosses
Outlast works particularly well as a smooth cross. Soft mains gain launch control, while shaped polyester mains can slide across the round surface.
Solinco has also packaged Outlast mains with Pro Stacked synthetic-gut crosses, demonstrating its intended hybrid versatility.
General Tension Guidance
Outlast is normally installed below a nylon or multifilament reference. Experienced polyester users can begin near their familiar range.
Lower tension adds pocketing and response. Higher tension lowers launch but can make the durability-focused string unnecessarily firm.
Use the racket manufacturer’s range and account for gauge, pattern and frame stiffness. The Tennis String Tension Calculator provides broad guidance.

Solinco Outlast Compared With Other Strings
Outlast vs Solinco Hyper-G Round
Solinco Hyper-G Round is another smooth co-polyester with stronger court-penetration and modern hybrid positioning. Outlast is more directly focused on value and durability.
Outlast vs Solinco Revolution
Solinco Revolution has six sides for much stronger geometric bite. Outlast is smoother and more neutral across shot types.
Outlast vs Tecnifibre Pro Red Code
Tecnifibre Pro Red Code is a firm round co-polyester with exceptional durability and control. Pro Red Code feels more traditional, while Outlast is positioned as a softer all-court value.
Outlast vs Luxilon 4G
Luxilon 4G is a premium round polyester known for tension stability. Outlast costs less, while 4G has stronger independent evidence and a firmer high-control identity.
Final Verdict
Solinco Outlast is a sensible choice for experienced players who value break resistance, a smooth round response and affordable restringing. Its construction supports reliable all-court control without the aggressive launch of a shaped spin string.
The TruTension claim is promising but should remain in manufacturer context because independent standardized evidence is limited. No polyester retains its original response forever.
The 16L / 1.25mm gauge provides the best general balance. Use 1.30mm for maximum resistance or a thinner gauge for denser patterns and more response.
Frequently Asked Questions
Is Solinco Outlast round?
Yes. Established gauge-specific specifications identify it as a round, smooth co-polyester.
Is Outlast durable?
Yes. Physical durability is its main strength, particularly in 1.30mm and 1.25mm.
Does Outlast hold tension well?
Solinco positions it as a major TruTension product with unusually strong co-polyester stability. Independent standardized data remains limited.
Which gauge should most players choose?
The 16L / 1.25mm version balances control, response and durability.
Is Outlast good in a hybrid?
Yes. Its round profile works in either orientation and is particularly useful as a smooth cross.
Does Outlast produce as much spin as a shaped Solinco string?
No. Outlast can generate useful spin through movement and snapback, but it does not have the geometric edges of Tour Bite, Revolution or Confidential. Players who create rotation primarily through racket-head speed may prefer its cleaner response, while players seeking maximum surface bite should choose a shaped option.
When should Outlast be replaced?
Replace it when launch becomes inconsistent, the mains stop returning or the stringbed feels noticeably less responsive. Waiting for breakage can leave a durable polyester installed well beyond its useful performance window.
Regular players should make that assessment after each demanding session rather than relying on appearance alone.
