One of the first multifilament strings to gain traction on the tennis court, Wilson Sensation excels using highly elastic nylon fibers that reduce dampening vibrations, resulting in a comfortable, more playable feel. This string features two outer wraps applied in opposite directions to improve durability. Now available in cool, striking blue, Wilson Sensation lives up to its established arm-friendly reputation. This 16 gauge string is slightly thicker than the 17 gauge, making it more durable.
