As a pioneer in sustainable and circular fashion, the TreeShirt Circular Women Dark Navy is a real highlight: when your TreeShirt is worn out, you can simply send it back thanks to our new "Circular Cashback" program. You get money back for both the material and the long wear. The longer you wear it, the more money you get - up to CHF 20. In this way, you help to close the cycle of raw materials and actively support the environment. You can find more information here.

The TreeShirt Circular was developed in such a way that it can be repeatedly returned to the material cycle and recycled without compromising on quality. It consists of 96% biodegradable polyester naNea and 4% biodegradable elastane. This allows the microparticles to break down in the environment instead of persisting in the long term. If it does need to be disposed of, it can be chemically recycled into raw materials for the next collection. The innovative naNea material degrades in seawater to over 93% within 99 days (according to ASTM D6691-17). Thanks to the Cradle to Cradle Certified® Gold certification and the use of naNea, the shirt leaves no harmful microparticles or residues behind. The striking orange embroidery on the hem symbolizes NIKIN's circular innovation and replaces the conventional flag label.
