ProNine X5 Composite Practice Baseballs – Dozen

The ProNine X5 is the composite practice ball built for programs that practice hard and hate replacing baseballs: a thin composite cover that outlasts regular leather, wrapped around a cushioned cork center with premium yarn windings so it reacts off the bat like a real game ball. ProNine rates it a great practice ball for college and high school, and it earns that on turf, in cages, and in weather that ruins leather dozens. Sold by the dozen.

Game-Ball Interior, Weatherproof Shell

The cushioned cork center is what separates the X5 from budget composites: it is the same center class found in quality game baseballs, so hitters get honest feedback and pitchers get a ball that feels right. The composite cover keeps water and turf abrasion from retiring it early, indoors or out.

Built for College and High School Practice Volume

A varsity season of live BP, machine work, and team defense drills is a meat grinder for baseballs. The X5’s medium seam height gives pitchers and coaches a true grip reference while the shell shrugs off the mileage, which is exactly the combination programs want in their everyday bucket.

Where It Fits

The ProNine X4 is the value composite with a PU and rubber center for youth programs; the WWA handles dedicated wet weather work in leather. Comparing composites? See also the DBat PRO C.

What is the difference between the X4 and X5?

The center. The X5 uses a cushioned cork center for game-ball response; the X4 uses a durability-first PU and rubber center at a lower price. Same composite shell idea on both.

Does a composite cover feel different?

It is thin by design. Off the bat the X5 plays like a regular baseball; the difference shows up months later, when it is still round and the leather dozens are not.
