For players seeking additional spin without sacrificing comfort, Volkl Power Fiber II 17 is designed to offer incredible playability and save a few cows in the process. The synthetic multifilament construction offers a soft feel with a large sweet spot and an added power boost. Power Fiber II features a unique high pressure resin misting process that requires less binding resin, allowing for enhanced tension maintenance. The final manufacturing step is to apply a patented coating designed to resist wear and prolong string life by protecting against fraying and notching.
Construction: Multifilament polyamide

Power Fiber II Review
String has good power and comfort. I used Power Fiber to dampen the string bed commonly associated with Poly in the mains. Unfortunately, the Power Fiber in the crosses only lasted two weeks. Nice string but it needs enhanced durability.
Excellent Spin Poly
The Volkl Power Fiber 17G has excellent spin and power. The string has consistent control and is soft on the joints. The string is fairly easy to string with too.
I got this string because my friend wanted me to help him string it on his racket. He likes it because its soft and powerful
Plays close to gut are far less cost.
I have never tried these strings but they turned out OK. Shifts a little but nothing you cannot fix, I get good pop on my serves and good amount of top spin.
I am satisfied the strings are comparable to Wilson 17g strings.
