Nobody unites fashion, form and function quite like Adidas. Specialising in sneakers and streetwear, the mega-brand has become a symbol of sports luxury. These black logo fleece sweat pants from Adidas feature an elasticated waistband, side slit pockets, an embroidered logo to the left leg and three signature side stripes. POSITIVELY CONSCIOUS: Adidas Group scores 4 out 5 by independent ethical brand rating agency Good On You. It uses eco-friendly materials in many products - 100% of its cotton is from sustainable sources and it's committed to use 100% recycled polyester by 2024. It traces and audits almost all of its supply chain to ensure good labour standards, and has committed to reduce carbon and water stress across its whole supplier base.
