the wilson ncaa championships game basketball is a slam-dunk ball creation! The national collegiate athletic association (ncaa) and national federation of state high school associations (nfhs) approved ball is the official basketball of the ncaa championships and ncaa march madness. With a high-grade microfiber composite leather cover, this basketball has a moisture-absorbent exterior for long-lasting performance. The ncaa’s patented aqua-grip laid-in channels replace traditional rubber with pebbled composite leather to displace moisture and enhance grip control. The cushion core technology carcass combines low-density sponge rubber and durable butyl rubber and provides a soft feel easier to grip and touch around the rim. The solution game ball, available in sizes 6 and 7, is suitable for top future athletes on indoor courts.
