Gamma Jet Tennis String is a co-polyester string with a twisted, ribbed shape profile and a textured surface. Jet is designed to help players get tons of spin while experiencing greater ball pocketing. Jet rewards players who deliver punishing shots from the baseline all day long. Gamma`s polyester strings use high energy co-polyester materials and are manufactured with a proprietary, multistage drawing process to increase strength and minimize tension loss for maximum durability and longer play duration.
