Babolat's Powergy provides comfort and power in a reasonably durable 16 gauge tennis string. Features a polyamide core (which lasts longer than traditional nylon), with two layers of monofilament wrappings (that increase flexibility), and a polyamide coating for added durability. The result is a softer playing string vs. the Co-Polyester strings, and more durability than traditional multifilaments.
