D-Ball American-Made Medicine Balls - The "Original" Slam Ball - D-Ball can make the claim to be the pioneer of the modern slam ball as we know it today with its original design of non-bouncing medicine ball, and for proudly being the manufacturer of the ONLY slam ball MADE IN THE USA! What makes D-Ball heavy balls different from other slammer balls on the market? D-Ball starts by using polyvinyl chloride (PVC), instead of rubber like most others, that goes through a unique rotational molding process perfected by parent company Mondo Polymers. Liquid PVC is poured like molasses into a mold, baked in an oven, and then cooled down to a flexible state. Each D-Ball slammer ball has a wall thickness of 3/8” no matter the diameter, as compared to 1/8” standard to most other core training balls in the industry. During product development D-Balls go through rigorous testing in an automated slam machine, being slammed repeatedly every 5 seconds until failure. What this ensures is that you will receive the toughest, thickest, most durable slam ball on the planet, designed to be thrown on any surface with as much force as possible. Plus, the fact that the D-Ball does not bounce creates additional workload during slam ball exercises as it must be picked up off the ground each time it is thrown down!
D-Ball's philosophy is to make a fitness product that is useful always and everywhere. Instead of just sand or imported metal shot like many competitors’ slam balls, D-Ball uses a proprietary mixture of 6-7 fill materials inside each ball. Because of this, each ball will have a consistent feel no matter the weight or exercise with no “slosh” effect. By merely changing the composition of the fill material, D-Ball can vary the weight dramatically from very light to super heavy (using USA-manufactured steel shot as a heavy metal filler), all the while remaining consistent within a single diameter size. This is not true with other manufacturers, who often have to keep increasing diameter of the slam ball to accommodate more, or heavier, filler material as ball weights increase. Some sand-filled balls will clump, harden, and become permanently misshapen due to moisture exposure, also referred to as the “concrete” effect. D-Balls experience no clumping, and no hardening due to the mix of fillers used. Moreover, a vent hole in the ball plug allows each ball to adjust to atmospheric conditions such as heat, cold, air pressure, and altitude. No matter where the balls are used, or whatever the temperature, the soft feel will remain constant.
