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?

Our tester found that the thermos could keep her drinks hot for up to three hours and that the battery lasts for about as long. Another standout feature (one also convenient for driving) is the thermos' lid: it's leak-proof, only needs a push to open, and gives you a 360-degree drinking experience—meaning you can essentially sip from any side of the mug.

"The lid is one of the mug’s best design features. ... When driving, I could lift the mug from any angle and begin drinking—no need to search for the side with the opening."Cheyenne Elwell, Product Tester

What to Look for in a Coffee Thermos

Hot vs. cold: Will you be using your thermos for hot coffee every morning, or do you prefer iced coffee? Some mugs keep beverages cold for hours upon hours but lack in the heat department, and vice versa. No matter the type of drink you plan to store, there’s an option on our list that will suit your needs.

Size: A huge coffee thermos may be great for the office, but if you’re bringing it on a walk or a bike ride, a smaller, lighter model may make more sense. Also, some larger thermoses might not fit in your car’s cupholder, so it’s wise to check those dimensions beforehand.

Lid Style: One factor that differentiates thermoses is the way you drink out of them. Typical options include a trigger-action lid, which is especially handy while sipping on the go, or a twist lid, which is common among leakproof models. Thermoses don't often have straws, like other reusable mug brands, but you can always buy a permanent straw separately if this is the style you prefer.
