67% of the denim in the men’s SS21 collection are part of Closed’s “A Better Blue” eco-friendly denim line, which the brand has developed with partners Candiani and Everest in Italy since 2018. The production uses 50% less water, 65% fewer chemicals and 25% less electricity in comparison to conventional jeans. The materials used include organic and recycled materials including cotton, polyester, and elastane. The dyeing methods also use less water, energy and chemicals with Candiani’s Kikotex® technology. Finally, Everest laundry’s washing techniques achieve used-denim looks with laser or ozone gas to reduce water and chemical use.
