Leisure 2 Extreme (L2X™) denim is made from a specific blend of fibers created to maximize performance, while retaining the look and feel of true denim. Integrating COOLMAX performance fibers into the denim allows moisture to be wicked towards the surface of the pant and away from the body. These hollow fibres also act as an insulator to keep the wearer warmer when it is cold. It is 30% lighter and stronger than traditional denim fabric, and offers advanced stretch technology for maximum performance. The addition of Silvadur™ silver ions naturally repels bacteria keeping your pants fresh.
