Babolat RPM Blast 18 is a co-polyester tennis string designed for aggressive players seeking maximum spin potential, precise control, and enhanced ball feel. Its octagonal profile and silicone-based surface coating promote string movement and snapback, helping generate heavy topspin during fast, full swings. The thin 18 gauge delivers increased responsiveness and ball bite compared to thicker versions, although it sacrifices durability and resistance to breakage.
Intermediate to advanced players with fast swing speeds who generate their own power and prioritize spin, control, and responsive ball feel. Particularly suitable for aggressive baseliners who prefer a thinner polyester string and do not frequently break strings.
