UltraSoft Diamond-Plate SpongeCote proves the old adage that two is better than one. The Nitrile enhanced Nitricell sponge is twice as thick but still absorbs repeated compression and bounces back to its original form better than any PVC sponge alternative. That means longer life and greater productivity improvement for hard working industrial athletes. UltraSoft Diamond-Plate SpongeCote doubles the defense against productivity robbing fatigue.
