Best Camping Thermos: What You Need for Your Next Trip in the Woods

Written by Dennis Owens

When you’re heading out on a hike for the day or even a longer trip, you always want to make sure you have something to drink with you. Even more, you want to make sure you have something that stays at the temperature you want it to be.

That means you can’t take just any old water bottle. You need a quality thermos that will keep the cold (or the heat) in. That’s where the best camping thermos can be your absolute best friend. Of course, that’s only if you already know which one is the best thermos. If not, here is a helping hand.

Things to Consider Before Buying a Camping Thermos

Don’t pour the drinks yet, before taking that nice thermos out from the store and show him the wildlife, let’s dwell in the list of things you have to consider before reaching your pocket to pick out your wallet.


The size of your thermos may be one of the most important factors because it’s going to determine how much you can carry in it. Now, for most people, the size of the thermos isn’t going to be enough for the entire trip, but it should be large enough so you don’t immediately have to stop for a refill.

You want something that will get you at least part of the way or through one day (though that may be asking a bit much as well). What may sound completely opposite of what we’ve just said here is that you want your thermos to be easy to carry as well.

different kinds of camping thermos

If you have a free pocket on the side of your bag, you will be able to put it there. On the other hand, you may have to carry it in your hand, and that could get tiring if you have an oversized thermos. Make sure you get something you can easily carry, whether it’s by hand or in the bag.

Length of Hot/Cold Time

This is the part that has most importance, at least for the most of the people. A good quality thermos should take care of that. There is no hard and fast rule about how long a thermos should keep your drink at the right temperature, but you should get at least a couple hours out of a good thermos.

Some of the best thermoses will keep your drink hot for over 12 hours and cold for over 24. You’ll likely spend a little extra for these thermoses, however, so keep that in mind when you’re looking for what you want to take with you.

Holds Ice

Contrary to some popular beliefs, not every thermos is capable of holding ice. Just because it promises to keep your drink cold for at least 24 hours doesn’t mean anything about being able to hold your ice cubes in it. This can be a good thing because it means the bottle itself keeps your drink cold, not any cooling aid you put in it.

On the other hand, it can also be a drawback, because it may mean ice doesn’t fit. Not every thermos has a large enough opening to allow ice to easily be added. In some instances, you may be able to make smaller ice cubes to get them into the opening, but in others, you will not be able to get ice in no matter what you do.

If having ice is important to you, make sure you look for a thermos with a larger opening to accommodate the ice being added through the top. That’s how you’ll keep your drinks even colder (and even longer).


In order to retain the temperature it says it will, for as long as it says it will, your thermos needs to be made of good materials. For the most part, this means stainless steel should be present in the construction materials. That’s where you’re going to get good temperature retention and a strong thermos that won’t break under a lot of use and abuse.

You also want the thermos to be BPA free and food grade. These things should be clearly visible on any packaging so you know it’s safe to use.

You may also want to look for a double-walled thermos, which is going to make it more durable but, even more importantly, add to the length of time it keeps your drink the right temperature (which is going to help with the point we already mentioned above).

Cup Included

Okay, so this is a relatively minor factor in the long run, but it can be a nice feature and that’s why it’s important to mention. Some thermoses are small and only have a small spout, easy to drink through. Even some larger ones may still be easy enough to drink out of.

When you get to the biggest ones, however, it’s often easier to have a cup that you can pour your beverage into. If you’re going to share with other people you want a cup to make drinking more sanitary as well. Some thermoses come with a cup as part of their lid. You’ll notice the lid that screws or snaps onto the top is actually quite large.

This is because it doubles as the cup you get to drink out of. Even if you’re the only one who will be drinking out of the thermos, the sanitary factor remains and makes it less likely something will get into the thermos itself.

Ease of Cleaning

The size and shape of your thermos will dictate how easy it is to clean. If the opening at the top is small you may have a hard time getting the soap and cloth inside. If it’s larger, you’ll be able to get it clean easier and that means you’re more likely to use it frequently. You also want to look at the material that it’s made of on the inside and outside.

This is going to affect how easy they clean and how much they may stain if you’re not careful. With stainless steel, you should be able to clean it quickly and easily. The same can be said about the outside of the thermos, which should be smooth and easy to wipe off when you may drop it in the dirt.

How to Carry

Look at what you can do to carry your thermos with you. If you can get one with a handle on it this makes it easier to take along. Most, however, don’t have anything to help you. That means you need to be able to hold it in your hand or put it in a pocket. Sometimes they are made with an ergonomic style so it’s easier to hold them.

The most important thing is what you want to do for carrying it. If you don’t care how you’ll carry it then don’t worry. If you really want it to be held a certain way you also want to pay attention to that. You also want any handle to be made of quality material so you don’t have to worry about breaking it if you happen to drop your thermos.
