Klean Kanteen Insulated Tumbler

Klean Kanteen is a family and employee-owned company based in Chico, California, that revolutionized the industry by introducing the first BPA-free social-purpose reusable water bottle in 2004. The brand was founded by Robert Seals and later purchased by the Cresswell family, who expanded the brand into a global leader in sustainable drinkware.

While the brand is headquartered and managed in the United States, its manufacturing occurs in China. Klean Kanteen works with hand-selected factories that meet high social and environmental standards, maintaining B Corp certification and 1% for the Planet membership to ensure their supply chain remains ethical and sustainable. The company remains independent and family-operated as of 2024, avoiding traditional corporate conglomerate ownership.
