Improve your baseball diamond with the Champion Sports Foam Filled Quilted Cover Base Set, built to withstand anything the game throws its way, all while maintaining a regulation size of 15" x 15" x 2". The heavy-duty quilted nylon cover is like a suit of armor for these bases, making them impervious to aggressive slides and cleat marks. But beneath that tough exterior lies a heart of foam, ensuring a soft landing for every diving runner. Securely anchoring each base are two steel spikes and two heavy-duty nylon straps, making setup and takedown a breeze. Just loop the strap through the spike, pound it into the ground, and adjust the buckle – your diamond is ready for play.
