Wilson Natural Gut Tennis String

The Wilson Natural Gut is the absolute pinnacle of tennis string technology. While synthetic strings attempt to mimic certain properties of "gut," this string remains the gold standard for tension maintenance, comfort, and pure playability. It is crafted from the fibrous serosa of bovine (cow) intestine, creating a unique molecular structure that no man-made material has perfectly replicated.

Wilson Natural Gut is legendary for its resilience. Unlike synthetic materials that stretch and stay stretched (losing tension), natural gut has "elastic memory," meaning it returns to its original state after every hit for a much longer period. This 16G or 17G string provides a "pocketing" sensation that is exceptionally soft, yet provides a distinct, crisp "thud" upon impact that many professional players refuse to play without.

Performance Profile

1. Comfort (10/10): The highest rating possible. It is the most arm-friendly string in existence, absorbing the highest percentage of shock and vibration.
2. Tension Maintenance (10/10): While polyester strings lose significant tension in 5–10 hours, Natural Gut stays "playable" and retains its tension until it actually breaks.
3. Feel & Touch (10/10): Provides a "connected" feel to the ball, making it the premier choice for players who rely on touch volleys, slices, and precise placement.
4. Power (9/10): Extremely efficient energy return. It provides "easy power," allowing the ball to travel deep with less physical effort from the player.
5. Durability (5/10): While it resists tension loss, it is sensitive to friction and moisture. It will fray over time and eventually snap.

Best Suited For

1. Players with Chronic Injuries: The ultimate "cure" for Tennis Elbow or shoulder issues.
2. Competitive Players: Those who want the same performance on the first day of stringing as the last.
3. Hybrid Users: Most commonly used as the "Main" string (paired with a polyester cross) to provide a pro-level blend of power and control.
4. Traditionalists: Players who appreciate the history of the game and want the highest-quality equipment available.

Care and Maintenance

Because this is an organic material, it requires more care than synthetic strings:

1. Avoid Moisture: Never play in the rain or on very damp courts. Moisture will cause the fibers to swell and lose their structural integrity.
2. Temperature Control: Store your racquet in a thermally lined bag (bag with "Thermoguard") to prevent the gut from drying out or over-expanding in heat.
3. Use String Savers: If you are a topspin hitter, using small plastic string savers can significantly extend the life of the gut by reducing friction at the intersections.
