The Babolat RPM Blast is a monofilament string that offers an excellent combination of effects, power and a unique feeling on impact. Thanks to its bonded silicone coating, the potential it provides is surprising. This string is the perfect choice for the modern player with a style of play like Rafael Nadal, Jo-Wilfried Tsonga and Sam Stour. This version of 1.30 mm calibre is even more durable.
