The Wilson Ultra 100UL V4 tennis racket is designed for the player looking for an ultra-lightweight racket that packs a powerful, effortless swing. The racket's sleek design allows the Ultra V4 to swing faster through the air and feel more natural in the hand, all while retaining best-in-class power that hits deeper through the court. The FortyFive high-performance carbon fiber construction is optimized to increase stability and energy return, while decreasing frequency. The Ultra V4 features a dynamic, color-shifting design where the racket color changes from ocean blue to purple haze as it moves. The V4's bumpers, grommets and end-cap are made of bio-based Agiplast, helping reduce waste while maintaining high performance.
