Certifications Glossary

Although the fashion industry is slowly recognizing the need for standardized measurement and verification of responsible production, there is currently no single independent certification standard. Many certifications focus primarily on just one step of the production process: either how the raw material was produced, or the environmental management of the mill or tannery where the raw material is transformed into fabric or leather.

We welcome you to learn more about the environmental certifications that independently verify that our products were made responsibly, and which stage of the production process that certification aligns with.

BlueSign
Mill/Tannery

Ensures that the material was produced with responsible use of resources and lowest possible impact on people and the environment, taking into account measures like traceability, water usage, chemical management, and worker safety.

FSC (Forest Stewardship Council)
Raw Materials

Verifies that the forest or other resource harvested for cellulose fiber is being managed in a way that preserves biological diversity and benefits the lives of local people and workers.

Global Organic Textile Standard (GOTS)
Raw Materials

Ensures that the cotton was grown organically, made without harmful chemicals (like chlorine bleach, heavy metals formaldehyde, and aromatic solvents), and that all chemicals that are used in processing meet requirements on toxicity and biodegradability.

Global Recycle Standard (GRS)
Raw Materials Mill/Tannery

Certifies that the fiber content was recycled with a clear chain of custody and ensures social and environmental compliance in its production.

ISO
Mill/Tannery

The International Organization for Standardization (ISO) has established multiple voluntary standards for certification. As examples from our supply chain, ISO 14001 assesses environmental management, ISO 9001 assesses quality management, and ISO SA8000 assesses factory social compliance.

Leather Working Group (LWG)
Raw Materials Mill/Tannery

The Leather Working Group maintains an Environmental Audit Protocol that promotes sustainable business practices within the leather industry, and ensures compliance along measures such as traceability, energy & water consumption, waste management & effluent treatment. There are 3 levels of certification (Gold, Silver, Bronze) based on the tannery's level of achievement against the protocol.

Oeko-Tex 100
Mill/Tannery

Verifies that no hazardous materials are present in the dyed, spun or woven material in accordance with the European REACH standards.

Responsible Wool Standard (RWS)
Raw Materials

Ensures wool comes from farms with a progressive approach to managing their land and from sheep that have been treated responsibly.

Sedex Members Ethical Trade Audit (SMETA)
Mill/Tannery

As one of the most widely used ethics audits, the Sedex Members Ethical Trade Audit (SMETA) ensures responsible business practices in labor, health and safety, environment and business ethics.

Worldwide Responsible Accredited Production (WRAP)
Mill/Tannery

Verifies lawful, ethical, and safe manufacturing based on audits by accredited 3rd party monitors.

Learn about our material origins
Substantial Silk
China

Deeply rooted in heritage and tradition, our silk is sourced from China where the fabric was invented nearly 5,000 years ago. Substantial in weight, our silk has a very high momme count, creating a finished product that is durable and luxurious to the touch.

Recycled Cashmere
Italy

Spun in the hills of Bologna, our recycled cashmere is made at a family-owned mill that has been in business for over 130 years. This regenerative process gives a second life to materials that would otherwise go to waste by creating a beautiful new fabric that is designed to soften with each wear.
