Popularized in the early 2000’s by Andy Roddick and Babolat’s top pros, Pro Hurricane is one of their earliest entries in the co-polyester family. Xtreme Futur Polymer was added during the manufacturing process to soften the response. Pro Hurricane is a throw-back of sorts and doesn’t play as stiff as RPM Blast, or RPM Blast Rough. The round co-polyester offers a good amount of pop and stronger durability than synthetic gut or multi-filament strings.   Construction: Extruded polyester monofilament   Color: White   Gauge: 16 g / 1.30mm   Features: -Softer than the average polyester -Xtreme Futur Polymer makes the string more comfortable -Durable
