Organic cotton, and what the certificate actually covers
The fabric comes from a GOTS certified supply chain under Scope Certificate CU846673GOTS-2026-00087084, issued by Control Union Certifications B.V. to GOTS version 7.0 and valid to 26 August 2027. A Scope Certificate covers the certified supply chain rather than the finished cover, and we do not sell this product as GOTS certified goods. Transaction Certificates for a specific order are available to specifiers on request.
What the cover does is mechanical rather than chemical. A tight weave with a measured mean flow pore diameter of 4.74 microns, no membrane, no coating. Twenty-one sizes.
