Volkl Power Fiber II

The Power Fiber II is engineered to mimic the soft, responsive feel of natural gut. While it is a synthetic multifilament, it offers a similar level of comfort and elasticity, making it an excellent, more accessible alternative for players who want that classic feel.

Volkl uses a high-pressure resin-misting process that packs more fibers into the same gauge while using less bonding resin. This denser construction significantly improves durability and tension maintenance compared to standard multifilament strings.

Yes, this string is specifically designed to be arm-friendly. Its multifilament construction provides a soft, dampened impact that absorbs shock better than stiffer polyester strings, making it a great option for players managing arm discomfort.

The Nylon 6.6 coating is primarily designed to protect the fibers and make the string easier to install during the stringing process. It does not negatively impact the soft feel or performance of the string, but it does help the string resist fraying and wear over time.

The 1.25 mm gauge is considered a thinner, '17 gauge' string. This thinner profile enhances the string's elasticity and feel, providing more power and spin potential, though it may wear out slightly faster than a thicker 1.30 mm gauge.
