Constructed with a higher density core than Agility mats, giving them extra weight and grip required for use in martial arts whilst still being suitable for rolling, tumbling, landing and other general gym activities. Ideal for Schools, Sports Clubs or Gymnasiums. British Standard BS 1892-3:2003 for flammability. All feature Blue PVC flame retardant covers, long-life heat welded corners and a non-slip latex base. The anti-slip surface of the mats needs to be cleaned periodically to maintain their efficiency. The upper surface (PVC) needs a wipe over with a mild cleaning solution as required. Tears should be repaired at once.
