Wilson New Ultra 100 is loaded with power, spin and precision. With a weight of 11.2 ounces, the Ultra 100 is perfectly suited for the intermediate player looking for an easy swinging weapon. It should also work for the advanced player who wants a light, explosive option. Comfort is improved thanks to the addition of Countervail, a material technology that lightens the load on your tendons and muscles. This model also comes with Wilson's Uncontaminated Design, which means it has the same bold simplicity and velvety paint finish found in the Pro Staff and Blade lines. To help with stability and control, the Ultra 100 features a structural reinforcement in the shaft (called Power Rib). This technology also features Crush Zone grommets in the throat, which compress at impact for added dwell time, comfort and power.
