Whether you take your coffee hot or iced, a reliable thermos will keep the drink at its ideal temperature for hours. In fact, the century-old vacuum technology used in thermoses was originally invented to keep liquid hydrogen (aka, rocket fuel) cold.
Today, thermoses can be found in the hands, bags, and cupholders of everyone from campers to commuters. Most are affordable, so picking the perfect one comes down to your specific needs. Do you want a trigger-action lid to sip while driving? Or a leak-proof bottle you can trust in your purse? Below are some of our favorite options, broken down into different categories to make it easier to decide.
For the coffee drinker on the go, here are the best thermoses to buy.
