The 40oz Klean 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 Klean Kanteen Classic so it's easy to fit one or two into a backpack or a cooler.
It comes with a Stainless Loop Cap that clips right onto a Kanteen S-Biner. Or you can opt for the stylish, functional and trail-tested Flip D-Ring Cap, available as an accessory.
Both caps are 100% stainless steel on the inside, 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).
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 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 Wide will keep your drinks fresh, crisp and clean tasting.
