Like every Klean Kanteen™ it's made from fully recyclable, 18/8, food-grade stainless steel, is 100% BPA- and toxin-free and doesn't need to be lined like aluminum bottles.

The large-mouth design makes it easy to pour in ice cubes or a smoothie packed with frozen berries. Cleaning the 18oz bottle is as easy as giving it a quick scrub or running it through the dishwasher.

It's also durable enough to last years and will never retain or leach flavors. No matter how many times you refill it, no matter what you put into it, the drinks in your Klean Kanteen™ Classic will always taste just right.
