What the seals mean
An extensive portion of our catalog holds at least one standard, certification or seal. That is your assurance that what you bring into your home has been tested for harmful substances, made with environmentally responsible processes, and produced under socially responsible working conditions.
Tested, traceable, responsibly made. Everything Standard 100 covers, plus production in environmentally friendly facilities and safe, socially responsible working conditions. Each label carries a unique ID you can look up.
Tested for harmful substances. Every component, down to thread and trim, is laboratory tested against more than 300 harmful substances, both regulated and non-regulated.
Organic fiber, verified end to end. The Global Organic Textile Standard covers certified organic fiber content plus environmental and social criteria at every stage of processing.
Authentic Egyptian cotton. The Cotton Egypt Association tests finished goods with DNA analysis and licenses the gold seal only to products made with genuine Egyptian cotton.
Cashmere from responsible herds. The Sustainable Fibre Alliance standard addresses animal welfare, herder livelihoods and grassland health at the source of the fiber.
