Wilson NXT Power 18 Tennis String - Set - Size 18G

NXT Power features high crystallinity xycro microfibers bonded with polyurethane for an ideal combination of soft feel and explosive power upon contact. It's been rated as the #1 comfort string by USRSA, and it features a 15% larger sweet spot and 80% less vibration than traditional synthetic gut string. The core is composed of a ribbon-like co-polymer, which increases its tensile strength and reduces the amount of tension lost while hitting shots. Originally labeled NXT Tour, this string's softness and comfort are about as close as it comes to natural gut. This 18 gauge string is the thickest in the NXT Power collection, which makes it the most durable. | Wilson NXT Power 18 Tennis String - Set - Size 18G
