Babolat's Boost D Prestrung Tennis Racquet is a cost effective racquet based off of the highly renowned Pure Drive Series. Even though the Boost D does away with many state-of-the-art technologies in order to reduce the price, it still offers a range of benefits that can help casual players and beginners up their game. For example, the 105 square inch head size gives you a large sweet spot, while the graphite racquet's lightweight properties allow for easy maneuverability and a quick swing speed. At a standard 27 inch length, the Boost D is also perfect for young players seeking their first full-sized racquet.
