The Klean Kanteen wide has a extra wide opening that makes it easy to fill and clean. It's an ideal size for juice and other naturally sweet drinks, and it also works great as a flask. Because it's made from food-grade stainless steel, these acidic beverages won't damage or corrode the metal.

It comes with a Stainless Loop Cap featuring a universal thread design. The 100% stainless steel inside ensures so your drinks never touch plastic. In fact, the only plastic on the Klean Kanteen Wide is on the outside of the cap; and of course it's BPA-free polypropylene (pp#5).

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 flavors. No matter how many times you refill it, no matter what you put into it, your Klean Kanteen Wide will keep your drinks fresh, crisp and clean tasting.
