Babolat Tonic+ Ball Feel is the same quality natural gut as Babolat VS, but without the same consistency in gauging (Ball Feel will be the thinner gauge of the two Tonic strings). Babolat’s exclusive Thermogut Technology Finishing increases durability by 25% and resistance to humidity by 60%. The new BT7 design reduces the number of filaments in the string from 15 to 7, but increases their size for added durability for the modern style of play.
