Introducing the Jack Sock Selkirk AMPED Pro Air Invikta! As opposed to his prior paddle of choice (the LUXX Control Air) the AMPED Pro Air produces more power, while still maintaining precision which matches Mr. Sock's style of play. And like the LUXX, part of the AMPED Pro Air's precision and speedy feel is due Selkirk's Air Dynamic Throat plus ThroatFlex Technology. Power starts with a thinner 16mm X5+ Polypropylene Core which is encased by Selkirk's 360 Proto Molding construction. Combined they produce a lively and consistent shot response in both offensive and defensive situations. Additional power and great feel across the entire paddle face is derived from the FiberFlex + Fiberglass base ply of surface material. And for long lasting world class spin potential and precision, Selkirk applies an outer layer of their ProSpin + NextGen Micro Texture to the AMPED Pro Air. The elongated shape of the Invikta AMPED Pro Air affords extra reach, a handle length of 13,3 cm and ranges in weight from 220-230 grams. All in all the Jack Sock Selkirk AMPED Pro Air is easy to swing and control points from anywhere in the court making it a great paddle option for newbies and elite players alike.
