When 27 ounces just isn't enough, this is. The 40 oz Klean Kanteen Classic is great for long car trips, camping, a late-night session at the office, a trip to the beach or any time you need to carry a lot of liquid and don't have the option of easy refills.
Just like every Klean Kanteen, the 40 oz 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, they 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 flavors. 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 their caps are BPA-free too, and they offer stainless steel cap options for Classic bottles as well.
The large-mouth makes it easy to throw in big stuff like ice cubes and quick to clean too just scrub it out with soap and water or toss it in the dishwasher.
