Whether you're heading out for a short hike or giving that big presentation at work, the 18oz Klean Kanteen Classic holds enough to keep you hydrated but is also small and compact so it fits easily into your bag, pack or briefcase. The very first Klean Kanteen ever made was about this size, so not only is this the 18oz Klean Kanteen Classic, it's also the original. So of course 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 some other metal bottles. The large-mouth design makes it easy to pour in ice cubes or a smoothie packed with frozen berries. And 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. Features: BPA-free
