Sustainability Score

65%
While COMME SI uses high-quality natural materials and maintains ethical manufacturing in Italy, they lack transparency in their complete supply chain and detailed sustainability reporting. They have made progress with organic cotton usage and plastic-free packaging, but could improve their environmental impact documentation and worker welfare disclosure. Their animal welfare policies are adequate but not comprehensive.
