"The Original" Stainless Steel Water Bottle

In 2002 we unveiled a 27oz Klean Kanteen® Classic; the original 18/8 stainless bottle designed to be the healthy alternative to polycarbonate and lined-aluminum reusable bottles. From the onset; free of BPA, Phthalates, lead or other toxins. Today, our Classic line continues to be revered by many for its iconic place in history and for its durability and prolonged performance.

Made from high quality, 18/8 food-grade stainless steel, the Classic is safe and toxin-free, and doesn't retain or impart flavors. No matter how many times it is filled, or what is put into it, these Kanteens keep drinks fresh and clean tasting. With a variety of cap and color options, tailoring a Classic to your lifestyle is effortless. The 1.75" mouth opening is easy to drink from and is large enough for ice cubes and bottle brushes (for thorough cleaning). The slim design of the 18 and 27oz size fit in most cup holders and many bike cages.

The award-winning Kanteen® Reflect raises the bar and is the ultimate expression of our ongoing crusade to change the way people think and drink. Beautiful in its simplicity and deliberate in its design, what you don't see is as important as what you do. No paint. No plastic. Made with just stainless steel, sustainably harvested bamboo and food-grade silicone.
