The Mikasa FIBA BD Series Compact 28.5″ Basketball (BDC2000) is a Size 6, official 28.5″ FIBA approved ball that features an ultra grip dimple composite cover and wide channel. Designed for indoor use. Mikasa finally did it. They added thousands of perfect dimples to their eight panel traditional basketball design and stamped them into the finest composite material made. It’s the least Mikasa could do for any serious athlete that takes basketball seriously.
