This 16-oz Thermos(R) mug features double wall insulation for maximum temperature retention, hot or cold. The unbreakable stainless steel mug is cool to the touch with hot liquids and sweatproof with cold. It fits most automobile cup holders, making it perfect for travel. With traditional containers, heat or cold finds its way inside through the process of convection. Thermos vacuum insulation creates an airless space between two walls, virtually eliminating the convection process and temperature change. Your drink will stay icy cold or steamy hot no matter what the forecast.

When it comes to what makes a great tumbler, just keep your eyes out for stainless steel. Function-wise, it’s the best material for the job. It’s clean, smooth, doesn’t trap weird tastes, won’t stain, and is aesthetically pleasing. As far as we are concerned, it’s an all-around great product. In case you didn’t know, stainless steel is also very easy to clean. Just use warm water and some dish soap.

Leakproof Drinklock Sealing Lid

Here’s something to ease your mind. While it’s easy to spill out of a regular mug, the Thermos Stainless King offers a 100% leakproof drinklock sealing lid. Simply switch the lever on the top one way or another. Not only does this thermos retain heat and cold, but it also reduces spillage. And it’ll save you the trouble of getting a new laptop in case you’re the kind of person prone to accidents. You can literally shake this tumbler around or even hold it upside down. It’s not going to leak.

In addition, you’re probably aware that plastic disposable coffee cups contribute to pollution. If you want to be eco-friendly when you drink, opt for reusable water bottles and reusable travel mugs. We’ve all created islands of garbage in the ocean and we could stand to take more action when it comes to carrying out environmentally responsible practices.

What Travelers Are Saying About the Thermos Stainless King 16 oz Stainless Steel Travel Mug

Overall, travelers seem to really love the Thermos Stainless King. Reviews praised the insulation properties, noting that the double-wall insulation kept their coffee hot for hours on end. One trick that really seemed to work was boiling the mug for 5-10 minutes before putting your coffee in. This will keep it hot even longer; we’re talking for up to eight hours.

In addition, it’s leakproof. We can’t stress how important that is. Add milk and sugar or creamer in your coffee. Then, you can just close it and shake it instead of stirring. Amazingly, users haven’t had a single spill doing this. The cover to the mug also comes in 5 pieces that are easy to disassemble and reassemble. If you’ve ever had a mug where funky smells got trapped in the lid before, we’re sure you will appreciate this ergonomic design. This mug lets you clean the lid thoroughly.
