Luxilon Element Soft IR is a round co-polyester tennis string designed for players who want more comfort and pocketing than a traditional control monofilament provides. It is a softer development of the standard Element concept and uses Luxilon’s Multi-Mono construction in a distinctive infrared-red color.
The word “Soft” needs context. Element Soft IR is flexible and forgiving compared with many polyester strings, but it remains less elastic and less arm-friendly than natural gut or a multifilament. Its combination of moderate power, spin and control is intended for players who can already generate racket-head speed but dislike an extremely firm stringbed.
It best suits intermediate and advanced players seeking an accessible polyester response, either in a full bed or hybrid. Players who are uncertain whether they need polyester, multifilament or another material can use the Tennis String Finder to compare the available profiles.

Material and Construction
Element Soft IR uses Luxilon’s Multi-Mono construction. Three flexible fibers are co-extruded inside a more durable polymer matrix, creating one monofilament string with multiple internal components.
This is more precise than saying that loose fibers are simply added to a conventional polyester. The integrated structure is intended to let the string flex and pocket the ball more readily while retaining the controlled response and physical strength associated with a monofilament.
Element Soft IR has a round, smooth profile. It does not use sharp sides or a rough surface to create ball bite. Spin is generated through string movement, snapback, dwell time and the player’s swing path.
Luxilon has published internal comparisons positioning Soft IR as more flexible than both standard Element 1.25mm and ALU Power Soft. Those percentages are manufacturer test results, not a promise that every player will experience the exact same difference in every racket.
The construction also should not be called a multifilament. Although Multi-Mono contains internal flexible fibers, the finished product remains a co-extruded polyester monofilament and retains the playing demands of that category.
Luxilon Element Soft IR Performance
Power
Element Soft IR is relatively lively for a polyester. Its flexible internal construction allows useful pocketing and energy return, making depth more accessible than it is with very firm control strings.
Independent playtesting has found a healthy level of response without placing the string in the same power category as multifilament or natural gut. Players with long, developed swings can obtain pace while retaining enough restraint to attack the ball confidently.
The string is also more usable on medium-paced swings than the firmest Luxilon products. It still requires sound technique and should not be expected to supply effortless depth for a beginner or a player with a very compact stroke.
Power can become less predictable after tension loss. Some independent testers found the response flightier on flatter shots late in the test, showing why useful life should not be judged only by breakage.
Power rating: 7.5/10
Spin
Element Soft IR provides strong spin despite its round profile. The smooth surface allows the mains to move, and its flexible construction helps the ball pocket before the strings return toward position.
Independent testing has recorded very good spin on both groundstrokes and serves. The response is less dependent on mechanical edges than a shaped polyester, giving it a clean and relatively predictable connection with the ball.
Players must still generate racket-head speed. The string will support a topspin swing, but it cannot create heavy rotation from a flat or hesitant stroke by itself.
Notching can eventually restrict lateral movement. When the mains remain displaced or spin shots lose their usual shape, the useful snapback may have declined even though the set remains intact.
Spin rating: 8/10
Control
Element Soft IR provides very good control for a relatively lively polyester. Its monofilament matrix limits excessive rebound, while the pocketing gives developed players enough feedback to direct aggressive shots.
The balance works particularly well for intermediate and advanced players who find rigid control strings too dead. They can accelerate through the ball without giving up all of the depth and forgiveness available from a softer response.
It is not as locked-in as Luxilon’s firmest low-powered strings. In a powerful frame or open pattern, the higher response may require an adjustment, especially after tension begins to decline.
Independent testing found control to be one of the string’s solid qualities when fresh, but also recorded reduced predictability later in the playtest. Regular assessment of launch and string movement is therefore important.
Control rating: 8/10
Comfort and Feel
Comfort is Element Soft IR’s defining advantage. The Multi-Mono construction creates a plush, pocketing response compared with most co-polyester monofilaments, and independent testers reported useful forgiveness on off-center contact.
The feel is muted and cushioned rather than extremely crisp. Players who dislike the rigid impact of a traditional polyester may appreciate the deeper pocket, while players who want immediate, firm feedback may prefer a standard control string.
Its high comfort score remains relative to the complete market. Element Soft IR is not as elastic as natural gut or a premium multifilament, and the response can become firmer once notching restricts string movement.
Players with recurring elbow, wrist or shoulder discomfort should not treat the name “Soft” as proof of arm safety. A softer material or carefully selected hybrid may be more appropriate, and persistent pain should be assessed by a qualified healthcare professional.
Comfort rating: 8/10
Durability and Tension Maintenance
Element Soft IR has reasonable physical resistance to breakage for a softer polyester. Its polymer matrix provides more abrasion resistance than a typical multifilament, while the 1.27mm gauge supplies a practical balance of response and material thickness.
The internal flexibility does not make it a maximum-durability string. Independent testing observed notching, and aggressive players can wear through or immobilize the mains faster than they would with a firmer, thicker monofilament.
Useful playability duration is the clearer weakness. Independent testers recorded noticeable tension loss and a change in response, with flatter shots becoming more prone to launching while spin shots could feel firmer as the notched strings stopped moving freely.
That combination shows why physical survival and playable life must be separated. Element Soft IR may remain unbroken after its original pocketing, control and snapback have declined.
Players should replace it when the strings remain out of position, launch becomes inconsistent or comfort changes materially. Waiting only for breakage can leave the string installed beyond its best performance window.
Choosing the Right Gauge
The consistently documented gauge for Element Soft IR is 1.27mm. This unusual diameter sits between many common 1.25mm and 1.30mm strings.
| Gauge | General characteristics | Best suited to |
| 16L / 1.27mm | Balanced pocketing, control, spin and resistance to wear | Intermediate and advanced players seeking the intended Element Soft IR response |
The gauge should not be rounded to 1.25mm or expanded into unsupported alternatives. Racket pattern, tension and swing style still influence feel and durability more than the small numerical difference alone.
Full Bed or Hybrid Setup
Full Bed
A full bed delivers the clearest version of Element Soft IR’s soft-polyester character. It combines moderate power, good spin and useful control with more pocketing than most Luxilon monofilaments.
This setup best suits intermediate and advanced players who already understand polyester. Players moving from multifilament should still expect a firmer and less powerful response.
Element Soft IR in the Mains With Softer Crosses
Using Element Soft IR in the mains preserves most of its control and spin character. Natural gut, multifilament or synthetic gut crosses can add power, pocketing and comfort.
Because Element Soft IR is round and smooth, it is generally less abrasive beside a soft cross than a sharply shaped polyester. The polyester mains can still notch the softer material over time, so longer physical life is not guaranteed.
Softer Mains With Element Soft IR in the Crosses
Natural gut or multifilament mains provide the dominant power and comfort, while Element Soft IR crosses add control and limit excessive launch. The round surface is appropriate for allowing the soft mains to move with less interference than a rough cross would create.
This orientation is the more comfort-focused hybrid. It also lets players use a polyester cross without choosing one of Luxilon’s firmest products, although any polyester can still increase the overall stiffness and wear of soft mains.
General Tension Guidance
Element Soft IR usually works best at a lower tension than the same player would use for synthetic gut or multifilament. Its softer category positioning does not make polyester equally elastic to nylon.
Players seeking deeper pocketing, easier depth and maximum comfort can begin toward the lower part of the racket manufacturer’s recommended range. Players who want a firmer launch can move modestly higher if the response remains comfortable.
Open patterns and powerful rackets can make the string feel livelier, while dense patterns can reduce movement and create a firmer result. Hybrid orientation also changes the appropriate starting point.
The Tennis String Tension Calculator can help organize these variables. An experienced stringer can then refine the setup through small adjustments based on actual depth, launch and comfort.

Luxilon Element Soft IR Compared With Other Strings
Element Soft IR vs Luxilon Element
Luxilon Element is the standard Multi-Mono option and provides a slightly firmer, more direct response. Soft IR adds flexibility and pocketing for players who prioritize comfort.
Element Soft IR vs Luxilon Element Rough
Luxilon Element Rough adds a textured surface and stronger mechanical bite. Rough is the more spin-focused choice, while Soft IR is rounder, smoother and easier to use as a hybrid cross.
Element Soft IR vs Luxilon 4G Soft
Luxilon 4G Soft emphasizes control and tension stability. It is firmer and lower powered, while Element Soft IR provides more pocketing, liveliness and initial comfort.
Element Soft IR vs Luxilon ALU Power Vibe
Luxilon ALU Power Vibe integrates dampening material to change impact feedback. Element Soft IR uses flexible internal fibers instead, producing its own plush and pocketing response.
Element Soft IR vs Wilson NXT
Wilson NXT is a multifilament with greater power and comfort across the complete market. Element Soft IR offers more monofilament control and spin for faster swings but remains the more demanding material.
Final Verdict
Luxilon Element Soft IR is a genuinely forgiving option within the polyester category. Its three-fiber Multi-Mono construction produces useful pocketing, moderate power and strong spin without the rigid response associated with many control monofilaments.
Its name still requires context. Soft IR cannot reproduce multifilament or natural-gut comfort, and its useful playability is limited by tension loss and notching. The 1.27mm gauge was intentionally selected and should not be simplified into a more common but inaccurate size.
For intermediate and advanced players who want a softer full bed or a smooth polyester component in a hybrid, Element Soft IR offers a balanced response. Players who prioritize long-term tension stability should compare 4G Soft, while players who need genuinely easy power and comfort should choose a softer string type.
