Entirely sterile with no markings.  The Urban Tracks pattern was one of the many camouflage patterns tested in the Natick trials (2002 – 2004) that resulted in UCP.  The fabric is 50/50 NYCO ripstop as used in most modern (2000’s) US camouflage uniforms and was probably printed by Navajo textiles: http://www.navajo-fabrics.com/PatternsAndShades.php
