All of our cotton products are made with materials sourced through the Cotton LEADS Program, assuring sustainably sourced cotton and a reliable supply chain. Slowtide polyester products (Quick Dry Towels, Yoga Towels, Fleece Blankets) are made from 100% recycled post-consumer waste, primarily plastic bottles, transforming it into premium polyester fibers. Polyester products are also certified through the Global Recycled Standard, which applies to the full supply chain, addressing traceability, environmental principles, social requirements, and labeling. All Slowtide products exceed the Oeko-Tex Standard 100 Certification, ensuring that they are safely produced and do not contain any allergic substances. The fabric has been tested and certified to be free of harmful chemicals so it is always safe to use! Visit the Responsibility page to learn more.
