Our premium hybrid exercise mono-fold mat uses XLPE for a crush-resistant core and polyethylene (PE) for the top and bottom layers for durability. This combination provides this premium exercise mat with the most comfort with the maximum durability in a commercial setting. The cross-linked PE center layer has the ability to crush and bounce back. The outer layer of tough PE has a thinner, but higher density material that is easy to keep clean and protects the softer form in the center of the fitness mat. This premium mono-fold fitness mat is equipped with a cutout handle for easy mat transport and positioning. The dimensions of this premium folding exercise mat are a large 1" x 2' x 5' to fit your biggest students. This folding exercise mat is ideal for junior high through adult.
