Wide-Mouth 40oz

The 40oz Kanteen® Wide is the ultimate bottle for long trips on the road or in the backcountry. When your adventure spans days or weeks instead of hours, when you need enough water to go the distance, when you're out all day and don't have access to easy refills, this is your bottle. 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 backcountry water filters. Even though it holds 8 ounces more than a quart-sized bottle, it's shorter and more compact than the Kanteen Classic so it's easy to fit one or two into a backpack or a cooler.

The 40oz Wide comes with either a Stainless Loop Cap or the swank and functional Flip D-Ring Cap. Both caps are 100% stainless steel on the inside, so your drinks never touch plastic. All Klean Kanteen products are 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, we don't need to coat the inside with a plastic or epoxy lining, which is one of the main differences from aluminum bottles. 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.

  • BPA Free

    Klean Kanteen has been free of Bisphenol A (BPA) since the very beginning. Our vessels are stainless steel inside and out (no plastic liners necessary), our lids are stainless and/or BPA-free polypropylene #5, and we use medical-grade silicone for our gaskets and baby products. We do it because we want the very best for our friends and family.

  • Easy Clean

    Our focus on health doesn’t stop with the materials we use. True to our name, we make products that are easy to clean—and keep clean. All our bottles, cups, and canisters feature rounded corners, large-mouth openings, and large-radius threads, so there are no hard angles that allow germs and bacteria to hide out inside. And most of our products are dishwasher safe.

  • 18/8 Stainless Steel

    Why stainless? It’s safe, durable, doesn’t react with other chemicals (like aluminum does) and doesn’t absorb, impart flavors, or leach who knows what (like plastic does). 18/8 stainless steel—the same material used in industrial kitchens and hospitals—is completely free of BPA, lead, phthalates, and other toxins. Why would we use anything else?

  • Lifetime Warranty

    Our goal is to reduce single use, plain and simple. So we make products that last a lifetime. We hope you’ll use (and use, and use) your Klean Kanteen bottles, cups, and canisters until there’s no life left in them. Many of our products are recyclable, too.
