Declared certifications.
And what they guarantee.
We list only third-party certifications declared by the manufacturer: some concern the environment, others the safety of substances or working conditions.
Certifies that every component of the finished product — fabric, stitching, buttons, labels, prints — has been tested against a list of over 1,000 harmful substances. Guarantees that what you wear contains nothing chemically dangerous to health. It says nothing about how the product was manufactured, by whom, or with what environmental impact: other certifications exist for those verifications. It is the world's most widely used and rigorous chemical safety standard for finished textile products.
