StayPut by Isagi Heavy Duty Professional is a non-slip fabric that can be used in all areas that need a deeper density protection and to withstand tough treatment. Isagi Heavy Duty Professional is made of a thick non-slip foam melded into a strong PVC mesh, supported by polyester fibres. The unique manufacturing process produces a robust sponge like fabric which doesn’t stretch, stick or rip, but will grip effectively on both sides.
