Klean Kanteen Insulated Classic 64-Ounce Bottle

Able to hold half a gallon, the Insulated Classic Klean Kanteen is the company’s largest water bottle yet. The 64-ounce bottle has double-wall vacuum insulation, which keeps hot drinks warm for up to 30 hours and iced drinks cold for up to 100 hours. The electropolished interior is nontoxic and rounded corners make cleaning easy. The included leakproof Loop Cap lets you clip the bottle almost anywhere, while the optional Sport Cap has a 25-percent higher flow rate.

In 2002, before stainless-steel water bottles were used for personal hydration, Klean Kanteen founder Robert Seals began working on his first prototype with items purchased at a local hardware store. Two years later, he released the first BPA-free metal hydration bottle. Today, Klean Kanteen remains a small, family-owned-and-operated company based in northern California, with an enduring commitment to health and sustainability. A portion of all proceeds support nonprofits that help protect the earth and promote environmental awareness.
