Klean Kanteen: 40oz BPA-free Stainless Steel Water Bottle

When 27 ounces just isn't enough, this is. The 40oz 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. The 40oz is available with the Sport Cap 3.0; featuring a soft silicone spout, 25% higher flow rate and "chirp" free hydration. Easy drinking and no whistling sound!

Klean Kanteens are made from high quality, 18/8, food-grade stainless steel; totally free of BPA and other toxins. Because stainless steel itself is safe, we don't need to coat the inside of the bottle with a plastic or epoxy lining, one of the main differences from aluminum bottles. Stainless caps are also available and all of our caps are BPA-free.

Supplier Code of Conduct

At Klean Kanteen, we provide high quality, long-life, sustainable solutions that replace single-use items. "Sustainable" is a word we don't use lightly. It means a lot more than just carbon offsets, recycled packaging or wind energy. A sustainable business consciously adopts practices that benefit more than the bottom line. We must consider the sum total of our interactions with people, the environment, culture and technology. We continually work to lessen our impact in four key areas: energy, water, waste, and chemicals. As we strive be a model and a leader, sustainability will continue to drive our decisions much as it was a driver of the invention of the first Klean Kanteen itself.
