Napapijri’s Circular Series of fully recyclable jackets has been recognized as Cradle to Cradle Certified Gold, the standard for safe, circular and responsible materials and products. In order to receive certification, products are assessed for environmental and social performance across five sustainability categories: material health, material re-use (achieved via either a biological or technical cycle), renewable energy and carbon management, water stewardship, and social fairness. The levels of certification include Basic, Bronze, Silver, Gold and Platinum. The items in Napapijri’s Circular series are 100 percent recyclable thanks to their mono-material composition. Fillings and trims are made of Nylon 6, while the fabric is made of Econyl Regenerated Nylon, a high-performance yarn recycled from discarded fishing nets and other waste materials. Their mono-material composition is said to simplify the recycling process as the fibers can be upcycled without losing any of their original characteristics.
