Best Thermoses TechnoBuffalo 2020

Nobody wants lukewarm coffee or any other beverage for that matter (but especially coffee.) A well-designed insulated thermos will keep your beverage at the desired temperature for hours. Some thermoses like the Stanley Classic Vacuum Bottle have lids that double as cups for sipping, while others can be popped open with the press of a button for drinking with one hand. A wide-mouthed thermos is great for soup or other hot foods when you're packing a lunch. Here are some of the best thermoses you can buy.

Which one should you choose?

The word "thermos," while initially a brand name, has come into popular accepted use as any insulated beverage container. Regardless of the name, the purpose of this type of container is to keep your hot beverages hot and your cold ones cold. All of the containers on this list have two or more layers of stainless steel and are vacuum insulated to keep your food or drink at a consistent temperature. You can't go wrong with any of them, but if you want a reliable classic, the Stanley Classic Vacuum Bottle is a safe bet. Stanley promises to keep your hot or cold beverage at right temperature for a crazy 32 hours. That's nearly a day and a half! The 18/8 stainless steel won't rust, and the hammertone powder-coat on the outside of the bottle is quite durable. The outer lid doubles as an insulated cup, so your drink can still stay warm or cool as you drink. The bottle is leak-proof for carefree packing. You can easily put ice into the bottle since the mouth is wide. Stanley has been making containers like this since 1913 and offers a lifetime warranty on their products.

However, if you're looking to sip your coffee or other beverage while you drive, you'll want something you can operate with a push-button rather than having to unscrew a lid. In that case, go for the Zojirushi Travel Mug. Go to any coffee forum online and ask people about their favorite travel mug, and this one comes up every time. Zojirushi has been making vacuum bottles, starting with hand-blown glass, since 1918. The lid of this mug forms a tight, leak-proof seal; you can toss it in your bag or purse and go. Press the button to drink on the go, or lock the button closed to avoid any liquid escaping unintentionally. The lid can be fully disassembled for thorough cleaning. Choose from two sizes, 12 or 16 ounces, and a handful of colors in each size.
