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 17 gauge string is slightly thicker than the 16 gauge, which makes it a more durable option.
