We made responsible choices on sustainable sourcing, ethical manufacturing and customer delivery to ensure we minimize our impact on the world around us. All ID products are made with Lenzing TENCEL™ Lyocell, sourced responsibly and naturally from eucalyptus trees in Austria while reducing water and eliminating chemicals. The fibers are woven into fabric in Portugal where our ropa interior is manufactured using best practices certified for ethical manufacturing. We eliminate all tags, labels and most packaging by using QR codes printed directly on all styles, and we offset carbon emissions for our compostable mailers.
