Babolat RPM Blast 15L Black Tennis String

Babolat RPM Blast 15L Black Tennis String — 1.35mm

The RPM Blast built for string breakers. The Babolat RPM Blast 15L Black is the thickest, most durable gauge in the RPM Blast lineup — delivering the same legendary octagonal spin, firm control, and co-polyester performance that elite players trust, engineered to last longer between restrings than any other gauge in the family.

The RPM Blast’s octagonal (8-sided) structure combined with a high-density co-polyester compound generates phenomenal ball rotation and exceptional spin on every shot, while the firm, precise response keeps your shots accurate and controlled even at full swing speed. The extra-thick 15L / 1.35mm gauge maximizes durability and tension maintenance — making it the ideal choice for powerful, aggressive players who go through strings quickly and need a setup that can handle the punishment of heavy, frequent hitting.
