If you like the idea of healthy eating, the chances are that you probably make your own food and take it with you to school or work. Some of those meals are tasty only if they remain hot or completely cold, so you’ll need the best thermos flask you can get. Our top pick is definitely the Thermos Stainless King Food Flask. It’s made out of quality, durable materials and it will offer you reliable service for years.

Are you of a more of an outdoor type? Do you often go hiking, climbing, walking, or swimming? Or do you maybe spend a lot of time working? Either way, you have thought to yourself at least a dozen times how it would be perfect to have a cup of hot tea to drink after an exhausting climb in chilly weather or just another cup of hot coffee to keep you functional during long working hours.

Everyone has heard of thermos flasks. These nifty devices can keep your beverage hot or cold for up to 24 hours, depending on the model, manufacturer, quality, etc. Fun fact: Thermos is a brand of thermal containers, but the word has also stuck in everyday usage as a name for all thermal containers.

Types of Thermos Flasks

There are several types of flasks, depending on their features and uses, but they all ultimately work on the same principle. We are going to list them here and hope that you’ll find what you are looking for. Ultimately, it depends on your individual needs.

The types we would like to mention are categorised by what they’re used for. They are all great insulators and offer amazing thermal protection. However, for example, if you just plan to use thermos flask to keep your coffee hot, you should concentrate on choosing from those that fit that need. Let’s start!

Thermos Flasks For Warm Drinks

If you need a thermos flask for bringing your coffee, tea, and other beverages with you wherever you go, you should purchase a good quality flask for warm drinks. The majority of thermoses can be used for both hot and cold drinks thanks to the double walls of the flask. This design provides great insulation for both hot beverages (keeping them warm for up to 12 hours) as well as for cold drinks (because a good quality flask will make sure that they stay chilled for a long time).

The great thing about these flasks is that they usually have a tight seal that will prevent any leakage and keep the other things inside your bag dry. Some of them even come with a cap that can also be used as a mug, which is great for when you want to go camping and want to bring a larger amount of coffee for you and your friends/partner. This type of thermos flask can be really practical to have in your car since most of them will fit the cup holder; you can enjoy a warm beverage even when you’re travelling a long distance.

The elegantly-designed flask comes with a stainless-steel cup that makes pouring your drinks much easier.

What to Look for in a Good Thermos Flask

We have already mentioned quite a few characteristics and features of thermos flasks; these remaining tips may be of less importance but they still matter. Some flasks can be priced a little too steeply for their capabilities; you might find yourself overpaying for features you do not actually need.

  • Size
    This one is pretty obvious: if you only need an extra cup of your desired hot beverage to get you through the day, you would most likely want to get the smallest available flask there is; maybe even consider getting a thermal mug. If you need a thermos flask to bring a lot of hot tea on a family trip to the mountains during winter holidays, you might want to consider getting a bigger one. Keep in mind the actual volume of the flask can differ from what is on the label – if it says your flask can fit a litre of liquid in it, it might fit anywhere between 950 and 1070 ml, which means measurements can deviate from 50 ml to 70 ml.
  • Ingredients
    Bisphenol A (BPA) and phthalates are both fairly common in everyday household items, but their amount must be within certain limits as prescribed by law. Both of these compounds can cause the disruption of endocrinal function and might even be linked to obesity, so you should always check the label carefully for the amount of these in your thermal flask (and anything else, really). Lead is also known to be dangerous to humans if found in relatively high amounts, which is why you should try to avoid getting a thermos flask that includes even the slightest amount of lead, even if it’s within permissible limits. Note that it is quite possible to find thermos flasks that are entirely devoid of these three possibly dangerous elements.
  • Soda-Friendly
    This problem might sound a little banal, but it can be a real headache for soda lovers: some thermos flasks cannot retain the bubbles and fizziness of your drinks, even if they can keep them ice cold. So if you like drinking carbonated beverages, you might want to check on this.
  • Cap Type
    The cap is as important as the rest of the flask, if not more. If the cap is damaged or low quality, the rest of the flask could be of double-wall vacuum insulated stainless steel and still fail to retain the temperature of your beverage, or might also leak! The best type of caps are the screw-on ones – bonus points if they have additional valves or other ways to make the cap stick tighter. Different types include flip lids, tumbler lids, straw lids, corks, and tumbler straw lids.
  • Maintenance
    Thermos flasks generally don’t require much maintenance, but you still should be careful in handling them. The golden rule is to hand wash them. Although some newer, dishwasher-safe models have recently appeared on the market, it would still be best to clean these gently under a stream of lukewarm water without using any heavy chemicals like bleach. Also, no rough scrubbers to rub away at their insides, as this can cause damage. Glass flasks are pretty low maintenance – the only thing you need to do after washing them is to keep them full of water while not in use to prevent residual odour from appearing and also to make sure you do not break them. Stainless steel flasks are the safest ones to use because of their antibacterial properties. They are to be cleaned only with a mild detergent and a soft bottle brush and should also be kept with their lids opened to prevent odour. They also require a certain pre-conditioning; if you are going to pour hot drinks inside, you will need to pour in some hot water beforehand to prepare them. Or vice versa – cold water for cold drinks.
  • Price
    It is understandable that sometimes making a costly investment seems like the best option, but before you spend 40£ on a thermos flask, step back and think about what it is that you need from it. If you realise you won’t be needing it to keep your drink warm for over 6-8 hours, you don’t have to buy one of those very expensive, super high-performance flasks. A simple single-wall flask might do the trick if you don’t need your water to stay ice cold all day long.
  • Brand
    This is just more or less common sense, and it goes for anything you are buying. The brands with the most positive reviews out there are Nayasa, Eagle, and Thermos, but that does not mean others are less reliable or produce lower-quality thermos flasks. Your ideal purchase depends mainly on what you need from the flask.
  • Infuser/Water Filter
    One of the most popular additions to thermos flasks is a tea infuser/water filter. There have a filter near the top which allows only liquid to pass through, leaving everything else – tea leaves, for instance – away from the remaining liquid in the bottle.
