Let's be real. Sometimes you want to ditch the backpack, the messenger bag or the briefcase and go light. When itty bitty bags, purses and even pockets call for an equally small H2O bottle, the Klean Kanteen 12oz Kanteen Stainless Steel H2O Bottle (Wide) is a Great fit. It's a little shorter and more small than the Klean Kanteen Classic and the 2-inch wide mouth gives it a Mason jar feel. Plus the Additional wide opening makes it super easy to fill and clean. It's an ideal size for juice and other naturally sweet drinks, and it also works great as a flask. Because it's made from 18/8, food-grade stainless steel, these acidic beverages won't damage or corrode the metal. It comes with a Stainless Loop Cap that works seamlessly with the Kanteen S-Biner. Or you can opt for the swank and effective Flip D-Ring Cap, available as an accessory. Both caps have a universal thread design and 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 bottles are made from 18/8 stainless steel so they don't necessity to be lined and will never retain or leach flavors. No matter how many times you refill it, no matter what you put into it, the drinks in your Klean Kanteen will stay New and delicious.
