Whether you’re rockin' out to "Ice, Ice Baby" or feelin' "Hot, Hot, Hot", the 20oz Kanteen® Wide Insulated will keep the temperature just right. Since it's our largest Insulated bottle, it can also hang with you for the long haul. Whatever food or drink you’re packing, whether you poured it in hot or cold, the 20oz Kanteen® Wide Insulated has double-walled, vacuum insulation to keep it that way: up to six hours for hot stuff, and more than 24 for iced drinks. Because the bottle is made from high quality, 18/8, food-grade stainless steel and has a 100% stainless interior, it won’t retain or impart flavors no matter what you put in it. That’s a good thing. Because the tastes of split pea soup, chai tea, and blueberry/banana smoothie simply should not be mixed.
