Top 10 Best Metal Thermos
for January 2023

Thermos bottles have been around for decades, and for good reason. They're durable, leak-proof, and come in a variety of colors, sizes, and styles. Thermos bottles are also popular because they're reusable, making them an eco-friendly choice. But thermos bottles aren't perfect. Most models use plastic, which doesn't hold up well over time and isn't good for the environment.

Thermos, however, is taking steps to change that. The Thermos brand is now making metal thermoses, which are durable, leak-proof, and can hold cold for 24 hours or hot for 8 hours. Thermos bottles are also insulated, which makes them great for keeping your coffee, tea, or soup warm or cold all day.

Thermos bottles are a popular item on Amazon, which is why we test Thermos bottles in the Different Guide . Our testers test thermoses for durability, leak-proofness, and insulation. They also test Thermos bottles for ease of use, including how clean the bottles get, how fast they heat up, and how comfortable they are to drink from. Here's our list of the 10 best metal Thermos bottles to buy in 2022, according to Different Guide Reviews test results and online buzz:

Soup Thermos Wide Mouth - Food Jar for Hot Food 10 oz - Non-Insulated Small Stainless Steel Thermo Lunch Box - Small Travel Vacuum Metal Container - Food Flask Wide Mouth

The Chestnut Soup Thermos Wide Mouth

What We like

This thermos thermos is the lightest and smallest size we've tested. Its vacuum insulation keeps soup hot for much, much longer than soup in, say, those cantaloupe cups, and it keeps small food items like cheese sticks and cold sides cold. The lid is tight, and the lidded opening is a bonus.
