Salming Challenge Squash String provides excellent power and feel to anyone's game. Made by DoubleAR in Italy, Challenge is a monofilament string which has had tremendous success in other racquet sports and making strides in squash. Slightly stiffer than comparable gauge multifilament squash strings, this string is made out of Ultranyl and features very good feel and durability for a string of its diameter (1.18 mm). We recommend dropping the weight of your usual string tension by 1-3 pound when using Salming Challenge to maximize the performance of this string.
