Klean Kanteen has always been stainless. Before Klean Kanteen, hydration bottles were made from either polycarbonate plastic or aluminum. We now know that both those materials are associated with a host of diseases and illnesses, info that wasn't common knowledge in 2004 when Klean Kanteen released the first food-grade stainless bottle onto the market. But there were studies, even then, that worried us and caused us to doubt the safety of the existing bottles on the market.The founders of Klean Kanteen wanted to give health conscious people a safe alternative to plastic and aluminum. So the very first Klean Kanteen was made from high quality, 18/8, food-grade stainless steel-a metal superior in both strength and safety that contains no harmful chemicals or toxins. No BPA, phthalates, lead or toxins.Now all those other companies that started out making plastic or aluminum bottles are crowing about their new stainless bottles. We got it right the first time because health has always been our top priority.Features include: Eco-friendly, recyclable, durable, designed to last, reusable, refillable. Large mouth openings - fit ice cubes and other big items like frozen berries, easy to fill and pour, easy to hand-wash. 100% stainless threads - no plastic threads or liner. BPA-free caps - made of BPA-free polyproylene (pp #5), all caps have safe, toxin-free silicone seal. Rounded corners - rounded corners are easy to clean with no hard angles where dirt, germs or bacteria can stick. Flavor free - food-grade stainless steel we use doesn't need to be lined with plastic or baked-on epoxy like aluminum bottles, so you'll never have to check to make sure the inside of your Klean Kanteen is still safe and intact. Because our bottles don't have a liner, they don't retain flavors or make drinks taste funky either. Easy care and use - easy to clean, dishwasher safe (some products should be hand washed).
