27oz 800ml Klean Kanteen Classic

The 27oz Klean Kanteen Classic is the most popular size and is perfect for your on-the-go life. Whether you're trying to juggle a full day of classes or work, the kids' extracurricular schedules, or a trip to dog park between your workout and happy hour, just one or two fill-ups will help you stay hydrated and happy all day.

The bottle 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 27oz Klean Kanteen Classic will keep your drinks fresh, crisp and clean tasting. Plus it weighs only 6 ounces and is durable and designed to last for years. All Klean Kanteen caps are BPA-free too, and stainless steel cap options are available for Classic bottles as well. The 27oz 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 allows you to pour in big stuff like ice cubes, and makes cleaning your Klean Kanteen Classic as simple as scrubbing it out or throwing it in the dishwasher. Yet the slim design fits into most cup holders and the the Klean Kanteen Kanteen Bike Cage.

Klean Kanteen Classic: Sport Cap 2.0

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.
