Whether you're rockin' out to "Ice, Ice Baby" or feelin' "Hot, Hot, Hot", the 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. With an all-stainless interior and no liner, you won't have any lingering flavors either. Because the last thing you need is junior coming home from school complaining that his smoothie tasted like your coffee from the day before. The leakproof Stainless Loop Cap creates an all-stainless interior in the bottle and gives you peace of mind if you want to toss it in a bag or lunch box. You can drink straight from the bottle, which has a cup-like feel and comfortable narrow rim, or the sleek Caf Cap to convert the bottle into a to-go mug. <br /> <br />
