Hugo Boss shirt made with 87% HeiQ AeoniQ, a regenerated cellulose fibre made with a unique manufacturing process, using PH-neutral chemistry and >99% of the water is recycled. This is different from conventional regenerated cellulose production, which relies on some hazardous chemicals and solvents to extract and spin the cellulose, and it is not a closed loop process. HeiQ AeoniQ fibre has similar elongation and tenacity to polyester (PET). Image HeiQ AeoniQ.
