Best Thermos for Coffee: Zojirushi Stainless Steel Mug

zojirushi best thermos

Something of a cult favorite and loved by everyone from GQ’s writers to that coworker who practically grows his own coffee beans, Zojirushi is a hundred-year-old brand from Japan renown for its quality and lifestyle designs.

Its stainless-steel mug is vacuum sealed, the standard when you’re shopping for the best thermos and is slated to keep hot beverages hot or cold beverages cold for hours.

The mug comes in a variety of finishes and colors that seem to hold up reasonably well, but here’s here’s what we like about this thermos:

The flip-open lid is secure, keeping your coffee from spilling and keeping the heat from escaping, without being difficult to drink from.

Most thermoses are difficult to travel with; either you have to unscrew the lid to drink (a pain and lets out heat) or you have an-easy-to-drink-from open lid that allows spills and heat seepage.

 Zojirushi’s like manages to avoid all these flaws.


  • 18/8 stainless steel interior means no weird smells or tastes
  • Easy to travel with
  • Two sizes (16oz and 20oz)
  • Stylish, modern colors and design
  • Extremely durable (even the paint); no complaints of lids popping open, either
  • Affordable


  • Some complaints about replacing the rubber seals; these might hold onto smells or tastes after a few months, and can be expensive to replace

Best Thermos for Soup: Stanley Classic Vacuum Bottle  

Stanley Classic best thermos

It’s difficult to beat a classic, and that holds true here. Another hundred-year-old company, Stanley is responsible for the green thermoses we saw our fathers, grandfathers, and even great-grandfather take fishing. 

One of the best thermoses for the money, the Stanley Classic Vacuum Bottle comes with a lifetime warranty. Depending on the size (16oz up to 2QT), the bottle will hold drinks hot for up to 32 hours and iced drinks iced for up to 160 hours. 

All sizes are leak proof and come with insulated lids that double as 8oz cups; this is part of what makes them suitable for lunch. No packing extra bowls here! You’ll also enjoy the thermos’ wide mouth (makes it easy to clean) and its classic, vintage appeal. 

We should note: while this thermos has nearly 3,000 reviews online, with 85% of those reviews being four-star or higher, many raise questions about whether it’s as good as it was in the old days. 

The answer is that the construction has changed: Stanley’s parent company went under and to cut costs, the new owners nixed the charcoal packing on the thermos’ outer wall in exchanged for thicker steel. The new thermos is lighter and costs less to make, enabling a classic American brand to continue. 

We think it’s as good as it’s ever been. 


  • 18/8 stainless steel construction 
  • Lifetime warranty covers parts and thermal efficiency 
  • Larger thermoses come with flat-packed handle for ease of use 
  • Extremely durable (just ask your grandfather about his!) 
  • Very affordable 


  • Made in China 

Best Thermos for Kids: Thermos Foogo   

ThThermos Foogo best thermos

In today’s school lunch world, in the midst of growing allergy concerns, children often aren’t to take advantage of the school lunch or the old stand-by: the sandwich. Thankfully, however, our best thermos pick for kids offers a way to send your kids to school with a hot lunch! 

The Foogo from thermos comes in two sizes (7oz and 10oz)--the largest holds almost a cup and a half of soup, pasta, meatballs, or other food. It’s slated to keep hot foods hot for up to five hours and cold food cold for up to seven hours. 

We love that this product is stainless steel; studies have found stainless to be highly effective at limiting bacteria growth, an important concern for children! The thermos strikes a good mix of not too wide for little hands to grasp (the lid is rubberized), but not too narrow. It’s both easy to eat out of and easy to open. 

Plus, the Foogoo is dishwasher safe, somethings parents adore, and comes in a variety of colors and designs to appeal to kids’ imaginations! 


  • Extremely durable 
  • Rubberized bottom to help keep thermos from flying off the table at lunch 
  • Double wall vacuum sealed insulation 
  • BPA free 


  • Might look too childish for older kids 
  • At 1lb, this thermos might weight down very small children’s backpacks!  

Best Thermos for Tea: Bamboo Tumbler With Infuser and Strainer  

Bamboo Tumbler best thermos

If you’re a tea-lover, you’ll love this thermos created with you in mind! While the interior is made of stainless steel and vacuum insulated, the outside is a bamboo, providing a beautiful, zen aesthetic in a world of sleek coffee tumblers. 

The other thing you’ll love is that this thermos comes with a removable stainless infuser and strainer so that you can make your tea on the go. The lid is also stainless, so if you value a no-plastic bottle, this product will get high marks from you. 

A question that many reviewers had before purchasing was about the infuser: can you drink tea from the thermos? The answer is, yes. You may drink from the thermos directly with or without the infuser still inside the thermos. You can also pour the tea into a ceramic mug or another kind of drinking vessel. 


  • Made from sustainably-harvested bamboo
  • Keep hot beverages hot for up to eight hours
  • Infuser for easy on-the-go tea drinking 
  • You can also use the infuser to create fruit-infused water!  


  • Screw off lid means possible heat leakage 
  • Older models will have a plastic lid 

Best Handheld Thermos: Yeti Rambler 30oz Tumbler  

YETI Rambler best thermos

You can’t have a conversation about the best thermoses available without discussing Yeti. An Austin, Texas original and cult classic, Yeti was originally known for its vacuum sealed coolers. Today, it has an entire line of thermoses in a variety of different sizes. Our favorite? The 30oz Rambler Tumbler. 

Accordingly, it’s possible that if you have a friend with a Yeti. Then he’s made you look at the ice in his tumbler because chances are it’s still there. Even after it’s sat in the car on a hot day. Furthermore, Yeti has combined the kitchen-grade stainless steel you’d expect from a top-of-the-line product with a shatterproof lid. 

This isn’t a thermos you can throw in your bag. However, the magnets in the unique lid will allow you to enjoy the perks of a sliding drink opening without fear of spilling. Plus, you’ll lose minimal cold or heat. 

Also, if you love taking a hot or cold drink out and about with you. Then you’ll give this huge marks. 

Finally, reviewers also love the many different color options now available in DuraCoat and custom engravings. The entire tumbler is dishwasher safe. 


  • Double wall means thermos won’t sweat as you hold it 
  • One of the best-rated thermos for thermal retention 
  • The magnetic snap lid makes thermos secure yet easy to drink from (no unscrewing lids) 


  • Can’t carry in a bag; must stay upright 
  • Very heavy! 

Best Thermos for Camping: Thermos Stainless King 

Thermos Stainless King best thermos

With over two thousand online reviews (and most of those highly favorable), the Stainless King from Thermos is a great combo of affordability and versatility. This thermos is another to take advantage of high-quality stainless steel and double wall insulation. 

Additionally, this thermos has a very wide mouth, and at 24oz, it’s a great size for handling everything from coffee to soup to oatmeal on a cold morning by the campfire. 

Furthermore, thanks to the wide mouth, it’s also very easy to clean. And Thermos promises it will stay hot for up to fourteen hours. 

Also, the screw on lids mean you get maximum thermal retention and increase spill prevention. When you’re camping, the last thing you need to worry about is spilling liquids! 

Finally, you’ll also find that the Stainless King is cool to the touch no matter how hot the interior gets. 


  • Won’t leak 
  • Easy to clean (great for camping situations!) 
  • Extremely durable 


  • Handwashing only (no dishwasher--though this won’t be a problem in the wilderness!) 
  • Large, which makes it inappropriate for backpacking 

Buyer’s Guide  

Now that you’ve reviewed some of our top picks for the best thermos award let’s talk about how to make sure you’re picking the right thermos for you and your needs. Firstly, you need to consider is the thermos’ material. 

Thermos Construction

Accordingly, as you can see from our list, we’re big fans of stainless steel construction, and for a good reason. Stainless is durable, resists bacterial growth, easy to clean, and does not retain odors or tastes. 

The downside? It’s heavy. 

Additionally, you can find thermoses made from plastic, glass, and other materials, but these typically have inferior thermal retention and durability. 

Furthermore, regardless of the materials used in construction, you want to make sure your thermos utilizes double wall insulation. A single wall will allow convection, or the transfer of air temperature to pass to the contents of the thermos, or vice versa. 

Two Walls Mean Better Heat Retention

When a double wall vacuum insulation is used, the air is removed from the space in between the inner and outer thermos layers. Because there’s no air in the space, convection can take place, and the contents of your thermos stay hot (or cold!) significantly longer. 

Also, your next consideration should be the lid and the size. Do you want a travel thermos that’s easy to grab with one hand and sip on while you drive to work in the morning? Do you need something that will keep your lunch piping hot for hours? 

A Few More Considerations... 

If you want to completely eliminate heat leaking, you’ll need a screw on lid. If, however, you want to be able to easily drink from your thermos. Then you’ll want something you can slide open with one hand. 

Be careful with size, as bigger isn’t always better. In fact, with thermoses, it usually means heavier! However, wider mouths typically make cleaning easier, so keep that in mind. 

Finally, pay special attention to the warranty.

A good thermos company will stand behind its product. Also, in this industry, lifetime warranties are not uncommon. 

​Which Will You Choose?

Accordingly, thermoses allow us to enjoy our favorite foods and beverages at times that we normally wouldn’t (like when we’re campingcommuting, or at work). So they’re an investment that should be carefully considered. 

Finally, the fun thing about choosing the best thermos, however, is that there is (almost literally) something for everyone. 

We can’t wait to see what you select for yourself!
