First high-performance polyester string composed of 100% recycled materials that generates the perfect blend of power, spin, and control. LXN Eco Power contains a durable, heavy-duty construction that's oriented for power, spin and control, yet forgiving when hitting delicate shots. It is the first string on the market made from 100% recycled materials, and it is a sustainable option that performs the same, if not better, than existing strings. This hexagon-shaped string grips the ball upon contact, which creates additional spin and keeps more shots inside the court. For those who have an all-around playing style and are looking to level up their game using sustainable products, the Eco Power strings are for you.
