Environmentally friendly and beneficial for your game. This is what the Luxilon Eco Power Rough tennis string can do for you. This string is made from 100% recycled material and has a hexagonal structured shape, allowing players to achieve maximum spin without altering their swing path. The textured surface also makes the string more flexible, providing players with a softer feel and greater tolerance for errors with every shot. These strings are not only a great choice for players looking to add more spin to the ball, but also for anyone seeking an arm-friendly string that causes no pain while hitting.
