The ProPenn Infinity balls are a step up in the realm of tennis balls. Featuring a completely new design with a whole host of internal improvements, these ProPenn Infinity balls are durable and longer-lasting than some other options. Penn has optimized these Infinity balls to offer a high-end experience with premium felt and consistency from one can to the next. For starters, their internal Impact Core is thicker and designed to promote increased stability and more energy return on your shots. Keeping the ball bouncing high and consistently is Penn's TrueBounce, while their new Spin Weave keeps balls from fluffing up as much while still feeling good on your strings. The felt is also brighter than normal for better visibility, thanks to Penn's Smart Optik 360 design. Lastly, Penn's reinforced rubber makeup in DuraPlay keeps the ball bouncing longer and truer over the course of extended hitting sessions. For a ball that's more than up to the demands of the modern game (USTA and ITF approved), consider the ProPenn Infinity. This is the Regular Duty version.
