From Austrian based, Lenzing, Tencel™ Lyocell and Tencel™ Modal fibers are utilized in many of our premium denim development processes because of their sustainable cellulose properties and their soft and smooth hand with almost 50% greater wickability than cotton. These cellulose fibers are created from sustainable forests–processes that reduce CO2 emissions.  For our mass merchant lines, we utilize various Rayon fibers that generally use less water and energy that the cultivation of cotton.
