Turf, wet grass, gym floors, morning dew, it does not care. ProNine calls it the perfect practice ball for youth leagues, and the price makes a case of them easy to justify. Sold by the dozen.\u003c\/p\u003e\n\n\u003ch3\u003eWhy a Composite Cover\u003c\/h3\u003e\n\u003cp\u003eLeather absorbs water and scuffs apart on turf and synthetic surfaces. The X4's thin composite shell resists both, so the dozen you buy in March is still in the bucket come summer. Indoors or outdoors, grass or turf, it is one ball for every practice surface, and it stays usable in wet weather that would waterlog a leather ball.\u003c\/p\u003e\n\n\u003ch3\u003ePlays Like a Baseball, Not a Toy\u003c\/h3\u003e\n\u003cp\u003eBudget-proof practice balls usually feel dead. The X4 keeps a real interior, PU and rubber center with premium yarn windings and a medium seam height, so it comes off the bat like a regular game ball and gives pitchers a proper seam to grip.\u003c\/p\u003e\n\n\u003ch3\u003eWhere It Fits\u003c\/h3\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/pronine-x5-composite-practice-baseballs-dozen\"\u003eProNine X5\u003c\/a\u003e is the step-up composite with a cushioned cork center for college and high school programs, and the \u003ca href=\"\/products\/pronine-wwa-wet-weather-baseballs-dozen\"\u003eWWA wet weather ball\u003c\/a\u003e covers rain-day work in full grain leather.
