Not all metal bottles are created equal when it comes to health and human safety. Ever since the very first Klean Kanteen was released in 2004, they have chosen to make their bottles from high quality, 18/8, food-grade stainless steel – a metal superior in both strength and safety that contains no harmful chemicals or toxins, including BPA. In fact, the National Toxicology Program recommends choosing glass, porcelain, or stainless steel containers to prevent exposure to BPA. And unlike aluminum bottles, there’s no requirement for a liner in Klean Kanteens, since stainless steel is recognized around the globe as a safe, food-contact material. 

WATCH OUT FOR SIGG – They are aluminum! Recent news in the outdoor industry has once again brought much attention and questioning about the presence of the chemical BPA in reusable bottles. Popular bottle makers, Sigg and Laken, publicly acknowledged for the first time last week that every aluminum bottle made and sold by their companies prior to August 2008 was knowingly lined with an epoxy resin containing BPA. Many scientific studies indicate BPA has the potential to act as an endocrine-disrupter when ingested, and fetuses, infants, and children are most susceptible to develop negative human health effects associated with BPA such as diabetes, heart disease, cancers, infertility, obesity, and neurological disorders.
