A single-layer 3D fabric of traditional camouflage synthetic fabric with outwardly extending random hollow tunnels therein with weldments in the fabric layer intermittently along the tunnels to hold the outwardly extending hollow tunnels in place. The tunnels have variable depth, typically ranging from between about 0.25 inches to about 2.0 inches. The 3D fabric is produced from a molding process that creates the outer dimensional layer. The 3D fabrics have unique visual properties which make them desirable for a variety of applications.
