Tecnifibre brings Lacoste styling and ultimate performance in T-Fight RS 305. The 305 is endorsed on the ATP Tour by top ten player Daniil Medvedev. RS refers to "R section", a unique 5 sided "R" shaped beam which combines the control benefit of a square beam design with the power of elliptical one. The T-Fight RS models have a constant 22.5 mm beam which is a change from the previous gen. Dynacore HD returns in the new T-Fight 305 with long braid continuous fibers to increase flex for more comfort at contact. The Xtreme Touch Construction returns and is placed just above the grip and in three key portions of the racquet head. XTC is a blend of graphite, alloy & polyester fibers specifically woven to enhance stability while improving the flex of the racquet. Tecnifibre filled the inside of the T-Fight 305 with foam to improve comfort and vibration dampening.
