An 18 oz vinyl cover protects 50 ILD polyurethane foam for extra softness and durability. Nylon mesh side panels let the mat breathe, and allow air to escape on landing. The 10'L x 5'W x 8" thick mat weighs 67 lb and includes attached, reinforced handles for easy portability. Primarily for competition use, the mats can also be used as teaching aids for skill development during training sessions. Mats meet all USAG, NCAA and NFHS competition specifications.
