Things to Consider Before Buying

Before jumping into buying your new thermos, there are a few options to consider. Below are five of the most important specs to look at and some tips on how to make the best choice for you!


Material always matters for gear, but especially when you’re going to be drinking out of it. Typically, beverage containers are made out of plastic, glass, or metal. Glass is great for home – easy to clean and sturdy, but a nightmare if it breaks in your pack. For camping, we tend to rely on plastics and metals, and there are a few things to keep in mind when choosing which one you want to use.

Stainess Steel Camping Thermos

There are several types of plastics used in thermoses, and you can even buy some products that only utilize plastic. However, many of these options have poor heat and cold keeping times and contain chemicals that can be hazardous to your health. While many of the products below use some plastic, all of them are BPA free.

Metal offers good insulation, sturdiness, and durability, but similarly can have some drawbacks for your health. Some types of metals rust more easily or can be bad for your body, so it’s important to check that your thermos is made from a bio friendly material like stainless steel.

Heat Keeping Time

This is perhaps the most common consideration in buying a thermos. Heat keeping time refers to the amount of time that your bottle will keep your beverage hot, and surprisingly, it can vary a lot. When looking for your ideal purchase, make sure you consider just how hot you need your drink to be, as extra insulation often means extra weight.

Thermos Hot Keeping Time

For car camping, fishing trips, and short hikes, a little extra weight may be worth it for piping hot coffee 12-24 hours after you leave the comforts of home. However, if you’re backpacking, a hot drink may not be as much of a luxury if you break your back carrying it in. In this case, 6-10 hours may get you your after dinner cup of cocoa without too much extra effort.

Cold Keeping Time

Just like heat, cold keeping time refers to how long your thermos will keep a drink cold. And, just like heat, this number varies quite a bit! Some thermoses claim to keep iced drinks cold for several days, while others just keep them from warming up in the sun. Make sure to consider the environment you’ll be using your bottle in extreme heat may make sense for a better cold time than a breezy mountain pass.

Thermos Cold Keeping Time

Another thing to consider along with the cold keeping time is how well your thermos keeps cold liquids inside the bottle. While most well built products won’t leak, a cold drink in a warm environment means condensation build up, which can leave your pack, camp chair, or table drenched if not wiped off regularly. If you want to stay dry, make sure you look for a condensation or sweat free product. If you’re tubing down a river or fishing on the lake, this may not be as important.


This consideration is more of a preference than an indication of quality, but it’s important nonetheless. Thermoses come in a range of sizes, and just the products below vary from 12 ounces to 2 quarts. While the “two liters a day” rule is always good to follow, you don’t necessarily have to fit all two liters of your hydration in your thermos.

Thermos Capacity

For solo hikers, self sufficient campers, and people with sharing problems, a small thermos is likely all you need – you probably shouldn’t drink two quarts of coffee. If you’re going to an area that’s especially hot or dry, consider upsizing, but for one individual 16-24 oz is generally an adequate size. If you’re bringing enough of your beverage for the whole crew, load up with one of the bigger options.

Cap Style

The last thing to consider in buying your thermos is what style you need. Most people looking for a thermos are content with the traditional design – a bottle with a stopper and a screw on lid. Most people, however, don’t know that you have options!

Traditional thermos caps are great for lazy campfires or trail breaks when you have your hands free and a place to sit down. They start to fall flat when you want to drink while mobile or keep your dishes to a minimum, and that’s where some of the alternatives come in.

Thermos Cap Style

Several thermoses feature wide mouth designs with vacuum sealed lids that allow for drinking like a regular bottle without losing the same amount of heat or cold. Others feature push buttons, permanent straws, or valves that make one handed (or, for the talented, no handed) hydration easy and convenient. If you plan to use your thermos on the go, such as backpacking, hiking, or running, these options might be for you.

Now that we’ve gone over some of the things to consider in buying a thermos, let’s get into the details!
