Babolat RPM Soft Tennis String

Babolat RPM Soft Tennis String

Babolat RPM Soft is the arm-friendly, comfort-first member of the RPM co-polyester family — a string engineered to deliver the RPM brand's characteristic topspin bite and tension stability in a construction that produces dramatically reduced arm impact compared to standard co-poly monofilaments. For players who want the competitive performance advantages of co-polyester string — spin generation, control, tension maintenance — but have experienced arm sensitivity, elbow issues, or physical discomfort with stiffer RPM Blast or similar co-polys, RPM Soft provides a genuinely protective alternative that doesn't require abandoning co-poly performance entirely.

• Soft Co-Polyester Compound Engineering - RPM Soft uses a specifically formulated co-polyester compound with meaningfully higher elasticity than standard co-poly monofilaments — the softer compound absorbs more impact energy at contact rather than transmitting it through the string bed to the arm, producing the reduced arm stress and more comfortable hitting feel that distinguishes RPM Soft from conventional co-polys. This is not simply a different gauge of standard co-poly — the compound itself is reformulated to change the fundamental stiffness-to-elasticity ratio that governs how impact energy is distributed between ball, string bed, and player arm.
• Arm Protection Without Performance Compromise - The critical achievement of RPM Soft's design is that the comfort improvements don't come at the expense of the co-poly performance characteristics that players are protecting. RPM Soft maintains meaningful spin bite from its string-surface friction properties, retains better tension stability than nylon multifilament strings, and provides the directional control that co-poly construction inherently offers. Players stepping from standard multifilament to RPM Soft get both better arm comfort and better co-poly performance — not a trade-off between the two.
• Appropriate for Arm-Sensitive Players - Players who experience lateral epicondylitis (tennis elbow), forearm soreness, or general arm sensitivity from their current string equipment should consider RPM Soft as a primary string solution rather than abandoning co-poly format entirely. Many arm problems in tennis are exacerbated by string stiffness rather than technique alone — reducing string stiffness through RPM Soft's softer compound can meaningfully reduce the repetitive impact stress that contributes to these overuse conditions while allowing players to maintain their competitive string setup.
• Senior and Masters Level Applications - Senior players whose arm resilience has decreased with age find RPM Soft provides the ideal balance between competitive performance and physical protection — the string's softer compound accommodates the reduced arm conditioning of older players while delivering far better competitive performance than the recreational multifilament strings many senior players retreat to for comfort. RPM Soft is the string that keeps arm-sensitive competitive players in the co-poly format rather than forcing a full equipment regression to accommodate their physical needs.
• Tension and Setup Recommendations - RPM Soft benefits from being strung at slightly lower tensions than conventional co-polys — the softer compound performs optimally at 48–56 lbs, where its elasticity can contribute meaningfully to power delivery and comfortable feel. Stringing too tight reduces the compound's comfort advantage without meaningfully improving control. Players transitioning from full co-poly should string RPM Soft 2–3 lbs lower than their standard co-poly tension to allow the compound's elasticity to express itself fully in the finished string bed.

Babolat RPM Soft is the solution for competitive players who need co-polyester's spin performance and tension stability in a construction that protects sensitive arms — the ideal string for players managing arm issues, senior players prioritizing comfort, and anyone transitioning from nylon to co-poly who wants the gentlest possible introduction to monofilament performance.
