TKPro Insulated Thermal Kanteen, 33 oz

Experience an on-the-go drinking experience from the OGs of reusable stainless-steel bottles. This one's got a cap that doubles as a cup, and allows you to pour from any angle, plus it's leakproof as all Klean Kanteen bottles are. And if your journey's taking you overnight, no worries—this thing'll keep your drink hot for 38 hours, and cold for even longer.

It’s hard to imagine that back in the early 2000s you couldn’t buy a reusable, stainless steel water bottle in the United States—plastic was pretty much your only option. When Klean Kanteen introduced their BPA-free stainless-steel bottles in 2004, they figured a few folks might be into them. They didn't know they'd become an international brand that has inspired dozens of other companies to make reusable stainless-steel products of their own.
