Made from fully recyclable, 18/8, food-grade stainless steel, a metal that's safe and totally free of BPA, phthalates, lead. Cleaning the 18oz bottle is as easy as giving it a quick scrub or running it through the dishwasher. The large-mouth design makes it easy to pour in ice cubes or a smoothie packed with frozen berries. The slim design fits most bottle/cup holders and standard bike cages.

Ever tried to chug water from a metal bottle with a sport cap? You know, a bottle you can't squeeze? Klean Kanteen's revolutionary Sport 3.0 is simply the best sport cap in the metal bottle market. Made with BPA-free polypropylene (pp#5), it was designed with one, simple moving part so it won't break or get crud in the works. 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. Cap is interchangeable with all Kanteen; Classic bottle sizes.

Review by sarah.a.montgomery on 9/10

It took me a little time to adjust to a stainless steel water bottle (and know when it's full or empty) but now that I have, I love it. I was a little worried at first that my water might taste like metal out of this kanteen, but it doesn't at all. The sport cap is very substantial (it has held up fine despite being dropped twice) and the cap that goes over the spout (not pictured) prevents spills.

Review by tdiehl on 9/1

This product is great. The Sport Cap is very nice and easy to use and the 18oz size is perfect for working out or around the house.
