At Klean Kanteen, we're a family & employee-owned business on a mission. And it's been that way from the start. We introduced stainless steel, BPA-free, reusable bottles in 2004 because we wanted a safe, non-toxic alternative to plastic water bottles. Klean applies rigorous third-party standards so we can be confident in our business and products-and so can you.
