Volkl Power Fiber Pro
Multilayer polyamide multifilament: thin-fiber core, polymer layer, two layers of thicker fibers and a polymer jacket; firmer polymer than Power Fiber II
Performance ratings
Overview
Volkl Power Fiber Pro is a firmer, more controlled and more durable version of Power Fiber II. Bigger filaments of a firmer polymer give it more control than a typical soft multifilament, while it still absorbs shock and vibration. Reviewers rate its power and feel above average and its spin below average, and durability reports are mixed. It comes in four gauges and several bright colors.
