Sensation is one of the first multi -eating strands that gain significant traction on the market and contain very elastic nylon fibers that reduce dampening vibrations for increased comfort and playability. This string has two external covers applied in opposite directions to improve durability. Sensation lives up to its established arm -friendly reputation for a great value for multi -filments. This 16 Gauge string is slightly thicker than 17 gauge, making it more durable.
