18oz 532ml Klean Kanteen Classic

The 18oz Stainless Steel bottle - A Safe Alternative to Plastic

Like every Klean Kanteen the 18oz is made from fully recyclable, 18/8, food-grade stainless steel, a metal that's safe and totally free of BPA and other toxins, so it 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 if you have a brushed stainless finish you can safely run 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.

The Klean Kanteen Sports Cap 2.0

From Little Acorns to Mighty Oaks, you can choose your Klean Kanteen with a range of caps - The poly sports cap 2.0 has an air vent to improve flow. This vent is plugged with a small silicone plug, the plug helps to keep the water inside, but this cap is not completely leak proof as this valve can sometimes leak a small amount if the bottle is on its side or upside down. For a completely leak-proof bottle, opt for the stainless steel flat of loop cap, or the poly loop cap. For more details on the Klean Kanteen please see our FAQ or our Klean Kanteen page.
