Yonex Poly Tour Air is a co-polymer monofilament with an elastic HR polymer additive. The result is a control string with impressive shock-absorption. In fact, this is the softest poly-based string we've tested by Yonex. This string also has great snapback for added ball rotation. Big hitters looking for a control string with above average comfort should love this one.
