Klean Kanteen 40 oz. Wide with Loop Cap

The extra wide opening is more than 2 inches in diameter for quick filling, pouring and cleaning, and the stainless steel thread design works with standard water filters. Even though it holds 8 ounces more than a quart-sized bottle, it's shorter and more compact than the Klean Kanteen Classic so it's easy to fit one or two into a backpack or a cooler. -Wide mouth for easy filling and pouring -Made of 18/8, food-grade stainless steel, no liner needed -100% stainless interior (18/8 stainless caps) -BPA-free and eco-friendly -Doesn't retain or impart flavors -Rounded corners are easy to clean with no hard angles where dirt, germs or bacteria can stick -Stainless steel threads -Dishwasher safe
