Engineered rubber overmold with reinforcing mesh provides extreme durability during slams. The interior ballast allows exercisers to slam extremely hard without having it bounce. High friction rubber with raised texture gives incredible grip, even when hands are sweaty.
Nice addition to my home gym
15 and 20 lb slam balls are of high quality and grip nicely and weight distribution is perfect so you can slam them as fast as tou can and transfer all your power smoothly. 10 lbs one seems to have uneven distribution of sand which moves when you throw, which doesn’t feel good, maybe the one that i got is bad.
