Klean Kanteen bottles do not have to have a special lining like some other metal bottles, and they won't ever leach nasty tastes or chemicals into your drinks--no matter how many years you use it. The large-mouth design makes it easy to pour in ice cubes or a smoothie packed with frozen strawberries. It's also easy to clean--just scrub it out with white vinegar and baking soda (or mild soap and water), or load it in the dishwasher. It's topped by a polypropylene looped cap that makes it easy to grab on the go. All Klean Kanteens are backed by a 1-year manufacturer's warranty.

The Klean Kanteen Kolor range.

Can I put hot liquids in my Klean Kanteen?
No. Klean Kanteen bottles are single walled and not for use with hot liquids. Warm beverages can be used at personal comfort level. The single-walled construction allows for more volume and the option to put your Kanteen on a flame.

Can I put my Kanteen in the freezer?
We do not recommend it and it will void the one-year warranty against manufacturer defects.

Can I put my Kanteen on a stove?
In a pinch, the Kanteen can be placed on fire or a stove. Beware not to melt the plastic lid or burn yourself.

What is stainless steel?
Stainless steel is an iron-containing alloy made from some of the basic elements found on earth: iron ore, chromium, silicon, nickel, carbon, nitrogen, and manganese. Properties of the final alloy are tailored by varying amounts of these elements. There are more than 57 stainless steels recognized as standard alloys on the market. Klean Kanteens are constructed from high quality sanitary grade 304 stainless steel which has a low nickel content. Stainless steel has excellent resistance to stain or rust due to its chromium content making it a material of choice among the food processing, dairy and brewery industries. Stainless steel is easy to clean, durable, inert and sanitary.
