The ONE45 BLX's BLX frame construction utilizes the volcanic mineral basalt and Karophite Black woven together. Basalt has enhanced vibration reducing qualities while Wilson's Karophite Black compound binds the basalt tightly together at a molecular level, providing further vibration dampening, resulting in cleaner feedback and a better feel. Additionally, the ONE45 BLX's 145g frame weight, 498 sq. cm/77 sq. in. size and 36.5cm balance all work together to produce a versatile racquet.
