Polyfibre Panthera is a medium firm co-poly designed for big hitters with long, fast strokes. This one comes loaded with bite, precision and durability. Our TW playtesters reported exceptional control from the baseline, even on their biggest swings. Comes in a very sleek & shiny red color. This one is slightly firmer than the average Polyfibre co-poly, so it is best suited to players who like a firm and controlled response.
