Crystal International Group Limited’s denim division, Crystal Denim, has unveiled CirClimate, a groundbreaking denim collection engineered for climate adaptability and full biodegradability. Developed in partnership with Advance Denim, the capsule uses Eastman Naia Acetate Renew and Tencel fibres merging environmental responsibility with high-performance functionality.

The CirClimate collection is entirely biodegradable and built on the ‘Design to Disappear’ philosophy. It incorporates 100 per cent cellulosic fibres, cotton threads, compostable packaging, and removable shank buttons, eliminating synthetic elements like polyester to reduce environmental impact. Unlike conventional performance denim, CirClimate offers all-season comfort without compromising on sustainability.

The key material, Naia Acetate Renew, is derived from sustainably sourced wood pulp and recycled content, offering a soft, breathable, and durable fabric. Unlike traditional performance denim, CirClimate is free from polyester, yet it delivers year-round comfort through temperature regulation and moisture-wicking capabilities.

“Our aim is to introduce more nature-based, eco-friendly collections to the industry,” said Janet Lui, Senior Manager - Product Development at Crystal Denim. “We are redefining denim to integrate climate-adaptive design and sustainability performance. CirClimate has passed rigorous moisture-wicking and temperature-regulating tests.”

Based in Hong Kong, Crystal International is reinforcing its commitment to circularity and resilient fashion solutions amid rising environmental challenges and shifting consumer values. The launch of CirClimate aligns with the Group’s Net Zero 2050 roadmap, underscoring its vision to lead the industry toward regenerative and climate-conscious fashion innovation.
