High-performance regular-fit tracksuit bottoms in moisture-managing stretch material with a decorative reflective logo and pattern by BOSS Menswear. For our RESPONSIBLE products we always use at least 60% more sustainable raw materials. This garment is made from at least 60% certified recycled polyester. Recycled polyester is an artificial fibre made from oil-based waste such as old PET bottles. It is a more sustainable option compared to conventional polyester, as we can reuse a material that has already been produced. Using recycled polyester also reduces plastic waste and stops it from ending up in landfills. We only use raw materials with a verified chain of custody to ensure the use of certified recycled polyester.
