LXN Eco Power offers a durable, heavy-duty construction that's oriented for power, spin and control, yet forgiving when hitting delicate shots. Designed for all-around players who want to level up their game and make a sustainable choice, this hexagon shaped string grips the ball upon contact to create additional spin and keep your shots inside the court. Adding a textured rough surface adds even more spin to each shot. It's like ordering spin with a side of spin. It is the first string on the market made from 100% recycled materials. A stringing note from Luxilon is to lower tension by at least 10%. Gauge: 16L Diameter: 1.25 mm. Construction: Monofilament Composition: Co-Polyester Shape: Hexagon Texture: Rough Colour: Grey Length: 40 ft. / 12.2 m. Made in Belgium
