The Babolat 2020 Boost A W Prestrung Tennis Racquet is made of 100% graphite to provide a good amount of stability and play-ability in a recreational racquet. The 16x19 string pattern is spin-friendly, and the sub ten ounce weight is very maneuverable. The 102 square inch head size offers ample forgiveness, comfort, and power. The 2020 Boost A is slightly head heavy so it offers a little bit more stability than racquets of a similar weight. The racquet comes prestrung for further convenience.
