This two-piece mat fits securely over a vault's base, providing an additional 4' x 8' of padded surface during practice or meets. The two pieces easily connect together with hook and loop fasteners to prevent it from slipping away from the base. The back side of the mat features a 4" flap with loop fasteners, allowing for extra landing mats to be anchored to the existing. These are made with 2 layers of foam— prime polyurethane foam and a thick cross-link polyethylene foam for additional padding, comfort, and safety. It's covered in a blue, 18 oz antibacterial vinyl to stop the spread of germs in group settings. 8'L x 4"W x 4½" thick.
