TENCEL™ Lyocell fibers naturally manage the transportation of moisture, enhancing fabrics by keeping your skin feeling pleasantly comfortable. Composed of natural material, the microscopic fibrils of lyocell cellulosic fibers are structured to regulate the absorption and release of moisture. This contributes to breathable fabrics that support the body's natural temperature regulating properties, creating a refreshingly cooling sensation on your skin. The fiber is also an environmentally-friendly yarn manufactured in a closed-loop system. The chemicals used in creating the man-made yarn are recycled and kinder to the environment. By using TENCEL™ Lyocell, we know that the material used, Eucalyptus in our case, is certified and that all raw material comes from forests that are not endangered. TENCEL™ Lyocell
