An enhanced outer wrap with wear-resistant microfibers further prevents notching, providing high levels of string durability. The patented Gamma TNT2 process provides comfort, control, and long-lasting performance. The React Pro design enhances string action, promotes great spin, and helps you pinpoint accurate shot placement. Play better and smarter.
