Sustainability Score

62%
While Minus33 uses natural merino wool and maintains some responsible practices, they lack transparency in their supply chain and manufacturing processes. Their animal welfare standards meet basic requirements, but they don't provide detailed information about their sheep farming practices. The company shows limited public commitment to reducing environmental impact and has minimal reporting on labor conditions. Their packaging and shipping practices show room for improvement in terms of sustainability.
