New Team Sports Throw Mats are the best value in the industry! A great additional landing surface for practice, at home or in the gym. Designed for light to moderate impact! The cover features 18 oz. premium vinyl covered polyester fiber fabric combined with a mesh breather cloth on the top surface. The Poly-Foam filler has been tested to provide the proper density and weight specifications required to achieve successful low to moderate impact absorption and stress-free landings Unlike other brands using 1.4. or 1.5 density Poly-Foam, Team Sports uses 1.8 density, which translates to a better quality and longer lasting foam. All Pro-Skill Throw Mats come standard as non-folding, and with blue vinyl and mesh breather cloth tops. (This is not a tumbling hard surface mat!)
