Featuring an AirLite Alloy construction for lightweight strength and power, the Energy XL delivers value for new tennis players. An oversized head combined with innovative V-Matrix Technology provides a much larger sweet spot, delivering more power with added forgiveness for better results. Stop Shock Sleeves at the 3 and 9 of the frame help reduce racket vibrations for improved feel, making this a solid choice to develop your game. It also is slightly longer in length, which gives players that little bit of extra reach to hit one more shot. Racket comes pre-strung so it's ready to hit the court when you are.
