18oz 532ml Klean Kanteen Classic

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.

Just like every Klean Kanteen, the 18oz Classic is made from high quality, 18/8, food-grade stainless steel that's totally free of BPA and other toxins. Because stainless steel itself is safe, Klean Kanteen don't need to coat the inside of the bottle with a plastic or epoxy lining, which is one of the main differences between a stainless steel Klean Kanteen and aluminum bottles.

Food-grade stainless steel is used in the brewing, food and winemaking industries too. It's the material of choice because it doesn't retain or impart flavours. No matter how many times you refill it, no matter what you put into it, your Klean Kanteen will keep your drinks fresh, crisp and clean tasting. All Klean Kanteen caps are BPA-free too, and stainless steel cap options are offered for Classic bottles as well. The 18oz Klean Kanteen Classic is also available with the new and improved Sport Cap 2.0 that's six times stronger and more impact resistant.

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

Klean Kanteen Classic: Sport Cap 2.0 (Included with purchase)

Ever tried to chug water from a metal bottle with a sport cap? You know, a bottle you can't squeeze? You end up feeling like a Hoover and yet you're still thirsty! Goodbye Hoover. Hello sweet hydration. Klean Kanteen went back to the drawing board and spent a year developing a new sport cap that delivers some serious flow, the Sport 2.0.

With 3x the flow of the first Klean Kanteen sport cap, a quieter valve, and a new and improved spout that's six times stronger than the earlier version of the Sport 2.0., this cap is guaranteed to quench your thirst.

If the old sport cap was a tiny, trickling creek, the new Sport 2.0 is Niagara Falls. It's also designed to last, just like Klean Kanteen bottles. Made with BPA-free polypropylene (pp#5), Klean Kanteen designed it with one, simple moving part so it won't break or get crud in the works.
