Klean Kanteen Classic 40oz Steel Bottle

Great for outdoor pursuits, road trips, and everyday use, the 40-ounce Klean Kanteen offers a versatile, reusable alternative to traditional plastic bottles. It’s made from durable stainless steel with rounded corners for easy cleaning, an electropolished interior that won’t retain or impart flavors, and a large opening for filling, pouring, and adding ice. Finally, the Sport Cap 3.0's soft silicone spout allows for an increased 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.
