A more sustainable choice for recreational players and coaches, the Head Reset tennis balls are perfect for training and developing skills. These ITF (International Tennis Federation) approved semi-pressurised practice balls are part of Heads Rethink project and feature a special compound including a pre-consumer recycled material that enhances durability. They provide optimal playability and a consistent bounce and have 50% lower air pressure than standard tennis balls. Additionally, the balls come in a 4-ball carton produced from 100% recycled materials.
