Dunlop Silk Pro Tennis String The Dunlop Silk Pro is Dunlop's premium natural gut alternative — a multifilament string engineered around the thermo-elastic PU resin coating and polymer treatment that most closely approximates the exceptional feel, power, and playability of natural gut within a durable synthetic construction. Where standard multifilament strings aim for comfortable performance, the Silk Pro aims higher: the gut-like feel that translates to exceptional touch on volleys, precise depth control on groundstrokes, and the elastic power response that makes gut the preferred string of the highest-level players who can afford to restring it. For players who want the closest synthetic equivalent to natural gut performance, the Dunlop Silk Pro is the answer within Dunlop's lineup. Thermo-Elastic PU Resin Construction — Gut-Like Feel — The thermo-elastic polyurethane resin that binds the Silk Pro's fiber bundles is specifically engineered to mimic natural gut's characteristic thermal elasticity — the way gut responds to temperature during play, maintaining consistent tension feel and a lively, spring-like contact quality that synthetic strings without this construction cannot replicate. Polymer Coating for Smooth Response — The polymer surface coating gives the Silk Pro a smooth, clean surface that reduces string friction during contact and provides a consistent, predictable feel across the string bed — the smooth response quality that makes gut strings so precise in touch and depth control during net play and groundstroke targeting. Exceptional Power and Comfort — Premium multifilament construction delivers the elastic energy response and impact shock absorption that generate Silk Pro's combination of effortless power and arm-friendly comfort — the dual quality that makes natural gut irreplaceable for players who have played with it and the quality the Silk Pro most closely approximates in synthetic form. Superior Touch and Feel Response — The Silk Pro's gut-like construction translates to exceptional touch feedback — the ability to feel where the ball is on the string bed during volleys, drop shots, and touch groundstrokes that separate the best synthetic strings from average-performing ones at point of contact. Available in 16G (1.32mm) and 17G (1.25mm) — The slightly heavier 16G gauge increases durability and full-bodied feel for players who hit with pace, while 17G's thinner profile maximizes the gut-like feel feedback and touch sensitivity that is the Silk Pro's primary performance advantage. Dunlop's Premium Synthetic Gut Standard — Positioned at the top of Dunlop's string lineup as the performance string for the most demanding players — tour-level construction in a format that delivers on Dunlop's string heritage and the brand's commitment to premium performance across their full equipment range.
