The newest protective coating improves the ever popular king of natural guts making Babolat VS Touch BT7 one of the most sought after strings around. Improving on the previous Thermogut coating, the new BT7 treatment claims to increase longevity by up to 15%, increase durability by 25%, and improve the resistance to humidity by nearly 60%. In addition to the new coating, VS Touch BT7 also features one more striking change from the classic natural gut, its new black color. Our testers found that the combination of the dying process and improved coating made this string play very slightly stiffer than the original VS Touch, but still provided all of the comfort and pop they love. Evidence of fraying was also lessened, hinting at the new improved durability. Definitely designed to be a favorite among all court players seeking ultimate feel, power, and most importantly, comfort, VS Touch remains the very definition of natural gut that other companies aspire to match.
