The 4G features maximum tension maintenance and a cushioned feel at impact, giving it excellent playability and adaptability to the modern game defined by power and spin. Featuring the elements of a control string without the loss of tension and discomfort of early polyester strings, 4G sets the standard for players seeking precision. The entire composition of this string has been designed to help players reach the next level, where molecular chains are strategically aligned to minimize tension loss over time and polyether-ether materials enhance strength and flexibility. The 1.25 mm gauge is slightly thinner than the 1.30, offering more feel and control with every stroke. In addition to its high-performance properties, the quality of these strings is unsurpassed. Even extreme weather conditions, such as rain and humidity, do not affect playability. These strings are highly appreciated by tour professionals, and are used by the Williams sisters and Grigor Dimitrov.
