The 2025 TFight 300S is the racquet Iga Swiatek uses as her base. It weighs 300 g unstrung and has a 98 in² head, a 16x19 pattern, a 22.5 mm beam and a swingweight of 321, with 66 RA. For 2025 Tecnifibre thickened and stiffened the RS Beam for more power, kept the strategic foam for a solid impact, and added the ISOFLEX system, which makes the string response more uniform and reduces losses on off-center hits.

The RR Score is not yet a precise figure. It summarizes the data we have today (specs and reviews) and changes as more information comes in. A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy.
