From the very beginning, Klean Kanteens have been built with love — the love of adventure, the love of conserving wild places, and the love of replacing single-use plastic. From water bottles to insulated tumblers, coffee mugs to pint cups, food canisters and lunch boxes to kids' sippy cups and baby bottles, we offer reusable stainless steel solutions for every day life. Climate Lock® double-wall vacuum insulation keeps drinks and food hot or cold for hours. Klean Coat® chip-resistant, powder coat finish is safe for people and planet. Steel straws, interchangeable caps, and other Klean accessories offer ultimate flexibility.
