Everything at the Blue suit is built on organic and certified materials — with one deliberate exception. The sewing yarn on our highest-stress seams is made from recycled yarn.
Why? Because the seams around the armholes of a jacket, and on the front and back rise of trousers, take considerable strain — every time you move, reach, cycle, or sit, those points are under pressure. We tested pure organic thread on these seams and it failed. After extensive research, we found the answer in a recycled yarn alternative, it held.
