Öeko-Tex (sounds like echo-tex) is a process that tests for over 100 harmful substances! To give you the more official description, Öko-Tex Standard 100 is an ecological certification process. We became aware of it through our vendors in Europe, where it’s widely known and used, and we’re pioneers in embracing it here in America. Certified garments are painstakingly tested for over 100 harmful substances, which is not inexpensive, but we believe so passionately in its importance that we’re committed to the investment. Our dedicated employee Kim corrals endless paperwork and telephone calls to keep every fabric, button, and zipper certified.
