Sustainability Score

72%
While the brand demonstrates strong commitment to organic materials and ethical manufacturing, there are areas for improvement. They provide good transparency about material sourcing but could be more detailed about their supply chain. Their carbon offset program is commendable, though their packaging could be more eco-friendly. Animal welfare policies are strong, but labor practice documentation needs enhancement. They show promise in sustainability but have room to grow in their ESG reporting and environmental impact reduction strategies.
