Overview
Kirschbaum Pro Line II is one of the softest and most responsive co-polyester strings available. Built on 20+ years of German polyester expertise from the company that pioneered polyester tennis strings, Pro Line II offers better pocketing and a more forgiving feel on off-center impacts compared to traditional polyesters.
