Crystal International Group Limited denim division has been pioneering sustainable textile innovation. The division, Crystal Denim, launched a revolutionary CirClimate sustainable denim collection, designed to be climate-adaptive while advancing circular fashion. Crafted by Advance Denim using innovative biodegradable fabric made with Eastman Naia Acetate Renew and TENCEL fibres, the capsule collection is biodegradable, and seamlessly blends sustainability with all-season functional performance.
Inspired by “Design to Disappear” concept, the collection incorporates 100% cellulosic fibres, 100% cotton threads, removable shank buttons, and compostable packaging, reducing waste and promoting fashion circularity. Unlike traditional synthetic performance fabrics, the CirClimate collection doesn’t require the usage of polyester in order to minimise environmental impact. Made with Eastman Naia Acetate Renew, a biobased fibre from sustainable wood pulp and recycled waste, this innovative denim fabric is entirely biodegradable, soft and durable. With the power of breathability, the CirClimate jeans combine temperature-regulating and moisture-wicking performance for year-round comfort, adapting to all seasons.
With temperature-regulating and moisture-wicking performance, the CirClimate jeans provide year-round comfort.
“We aim to bring more nature-based, eco-friendly collections to the industry. We are redefining denim to embody our dedication to integrating climate-adaptive design and sustainability performance. Our collection has passed temperature-regulating and moisture-wicking performance tests,” said Janet Lui, Senior Manager – Product Development at Crystal Denim.
In response to the evolving consumer needs and environmental challenges, Crystal International will continuously pioneer resilient fashion products to mitigate climate impacts, echoing with the Group’s commitment towards Net Zero 2050.
