The HEAD Graphene 360+ Speed PWR Tennis Racquet is the most powerful racquet in the Speed lineup. The 115 square inch head helps the ball explode off the string bed, and makes the sweet spot enormous. At 27.4 inches long, there is more reach and extra oomph on stretch volleys and overheads with the Speed PWR. The 16x19 string pattern is a perfect for players who impart impressive spin on their shots, be it slice or topspin. Lastly, Graphene 360+ combines the stability and ball speed of Graphene 360, with innovative Spiralfibers in the lower hoop which untwist and stretch at contact for a unique, flexy, feel. At only 9.0 ounces unstrung, the Speed PWR is an incredibly lightweight and easy to maneuver.
