Out the door? My pick for best thermos to keep food hot or cold is the Ember Temperature Control Travel Mug.
If you're currently hitting the drive-thru for your morning coffee – have you considered carrying a thermos instead?
Not only will it save you time and money, but it's better for the planet. Today I'll share a few tips and reviews to help you start shopping for the best thermos for your needs.
In this section, I'll cover what you should consider when picking out a thermos. By the end, you'll be able to find the best container to keep food hot – or cold – without any feature envy.
You don't want to get too small a thermos or one that doesn't work for your food. You can technically use most thermoses for both liquid or foods, but certain thermoses work better for cold drinks while others are geared more towards food.
Having a cold thermos with a built-in straw is handy for drinks. On the other hand, having a thermos with a wide mouth is better for lunch applications.
If you are only planning to use your thermos for coffee, you may only need to look for the standard-sized 16-ounce mug type. (Although depending on your coffee intake, you may want to go larger!)
Find a size that fits your needs... and also fits in your bag or purse.
Depending on their construction, high quality thermoses can keep food temperature stable for 5-10 hours. If you need to store food longer, you can also grab an electric thermos which holds a charge and heats or cools on batter power.
Your next significant consideration (and it is an important one) is the thermos' insulation. You want to make sure it keeps what you put in the thermos stays hot (or cold).
There are several options when it comes to insulation. I particularly like vacuum insulation, which is an excellent feature if you plan to use the thermos for a long time. With no air between the outer and inner walls, heat is not able to transfer out, allowing for very little heat loss from your contents.
The most critical part of these products is the amount of insulation that they have. Since vacuum insulations vary, consider how long you need the content to stay warm.
A good guideline is that a hot item should keep about five hours of heat retention. High-quality thermoses can even beat that time.
You also want your thermos to be durable – thermoses tend to be used a lot outdoors.
If your thermos breaks, you run the risk of hot liquid potentially spilling out (or you may lose the heat retention feature and render it useless.)
If you choose a vacuum insulated product, this shouldn't be a problem as durable materials are needed to hold the void together – these thermoses are usually well-made.
Stainless steel is typically what you will see thermoses made out of – it's strong enough to hold a vacuum and withstand any accidents. Plus, stainless steel tends to be rust-resistant, which is an excellent feature in a thermos.
Remember, any product that you are carrying liquids or food in should be leak-proof.
There is nothing worse than buying a container that ends up leaking all over your purse. Not only does a leak-proof product help you avoid spills, but it also shows you how well your coffee is going to stay hot.
When evaluating your thermos, also consider the lid. There are several types of lid designs that you will see as you shop. Some lids come with push-buttons for ease of use while others use screw tops to ensure the best insulation. You can also find thermoses with a straw in the cap for easy access.
Which design you end up with it is entirely preference-based, but keep in mind that for the most insulation, a cap is the best choice.
Capacity is another critical issue in a thermos. Depending on how much you eat or drink, also consider how much the thermos will weigh in your bag.
If you plan to take your thermos backpacking, a larger one is not only heavier, but it also takes up valuable pack space. If you plan to use your thermos in your car, make sure the capacity isn't too large to fit in your cup holder.
As long as your circumstances allow for it, though, I prefer a larger thermos.
As with any product, thermoses have differentiating features that may appeal to you depending on your needs.
Like I mentioned above, lid construction is an interesting design feature. You can get a lid with a straw inside, or one with push-button operation.
Of course, if you aren't interested in a fancy lid and are just drinking coffee on your commute, a simple lid will do.
The size of the thermos' mouth can vary a lot depending on the manufacturer. Some will have wider mouths, so you can drink or eat from it easily, while others use a small opening to make the most of the insulation feature. If you have a food container, it is fatter and shorter, which makes it easier to maneuver a fork or spoon.
The thermos' grip is another feature that can vary widely. Depending on how slippery or wet your hands are when using it, a stainless steel thermos may not be the right choice. In that instance, finding a thermos with a rubber grip or a powder-coated finish will help to improve the grip.
Thermoses can also come with a carry handle. I love having this feature for food while I know others find it annoying. Again, it also depends on your personal preference.

Unlike other travel mugs, the Zojirushi gives more heat retention thanks to its tight-fitting lid – you can store it in your purse without worrying about spillage.
