The Six-One Lite version is the lightest of the Six-One player series. Players will find a spin-friendly and crisp response from the Six-One Lite BLX. The BLX technology incorporates fibers of basalt, a natural volcanic rock, into the Karophite Black. According to Wilson, the result is a significant reduction in vibrations in the racquet. Ideal for good juniors stepping up into a full size senior racket!
