At Salts & West Clothing, we are proud to say that our made in Canada clothing items are Oeko-Tex Standard 100 certified to ensure that they are Non Toxic. You're probably thinking, "Great, but what exactly does it mean?". By definition, Oeko-Tex is "the best known and most widespread test label worldwide for textiles tested for harmful substances." Okay, let us break it down for you. Oeko-Tex Certification is a system that is used to make sure textile products, like Salts & West clothing, do not contain any harmful chemicals.
