Dunlop Biomimetic S-Gut 17 utilizes a large monofilament core to provide a solid feel and tension maintenance. S-Gut also features smaller outer wraps to increase feel and soften the stringbed. The result is a comfortable basic synthetic gut string, perfect for players looking for a solid playing string without breaking the bank. Biomimetic S-Gut also makes a good string to use in a hybrid, such as to soften the stringbed when used with a polyester string.  Gauge: 17 / 1.22mm Length: 40ft / 12.2m Composition: Monofilament core + Outerwrap Color: Green
