The TreeShirt Circular in Dark Navy combines innovative design with circular fashion. Because: 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.

Made from 96% naNea, a biodegradable polyester and 4% biodegradable elastane, the TreeShirt Circular ensures that no harmful particles remain in the environment or water during its useful life. If it needs to be disposed of, it can be chemically recycled into the raw materials for new products. The innovative naNea material degrades in seawater to over 93% within 99 days (according to ASTM D6691-17) - without leaving any harmful microparticles or toxic residues. Cradle to Cradle Certified® Gold certifies the sustainability of the product and that it contains no harmful substances. The eye-catching orange circle sticker on the hem replaces the usual NIKIN flag label and symbolizes the circular innovation of NIKIN products.
