Investing in a good thermos can make your life easier in many ways. Besides saving you the morning hustle, a thermos flask allows you to extend the warmth or coldness of your beverages or food to the outdoor so you can enjoy your drinks on your own time. Sometimes all you need to boost your moods is a cup of hot coffee or a steaming bowl of soup. These convenient drink containers have been around for quite some time but now come in several different colours, sizes shapes, designs, and so on.

Buyer’s Guide – Choosing a Thermos Flask in the UK

A good thermos flask can give you several years of service and even add greatly to your lifestyle. If you need a Flask for those cold camping trips, see our guide on the Best Tents. Other than having your favourite drink at all times, it allows you to take drinks all the time, especially when on long trips. There are numerous excellent options to choose from when shopping for a thermos flask. They come in different models, sizes, and with varied features. Therefore, if you are thinking of getting one, here are some of the important features to look for.

  • Size

Do you find yourself wishing for a new thermos every time you have a different need? Well, it’s probably because you tend to look for different capacities in them. For instance, if the contents in your thermos are intended to hydrate two or more people, then its capacity would have to be larger. If you prefer something small and light then it would make sense to go for the smaller options.

  • Insulation

The level of insulation determines how long the thermos flask can maintain its contents temperature, whether hot or cold. There are two major types of insulation; foam and vacuum insulation. The best option would be a vacuum flask as it able to keep your drinks at their original temperature for longer hours. Vacuum flasks are made with double-walled stainless steel that creates a gap between your drinks and the exterior part of the bottle, which stops heat or cold from getting in or escaping. So, if you need a thermos for overnight use, you’ll have to invest a bit more in vacuum flasks. In addition, a good flask should be able to keep cold stuff longer than it would maintain hot drinks.

  • Useful Accessories

Depending on how you plan to use the flask, there are several accessories that can come in handy. Some of them include multiple lid options, a long spoon carry, handle/strap, a stainless steel serving cup, a tea hook and much more.

  • Attractive Looks

There are many thermos flask models and designs around these days; therefore, you can get one that fits your needs. For instance, there are elegant flasks, others with sports models, and others with a fun look to choose from.

  • Durability

Your thermos sees a lot of outdoor use; therefore, go for something that can take a few dings without losing its thermo-regulation capacities faster. Your best bet would be stainless steel options that have solid or protected lids. On the other hand, those with quirkier designs are best used at home as they are more likely to falter with a few blows.

  • Leak-proof

Imagine reaching out for your drink and finding your bag drenched in your favourite soup, coffee, or tea. Some thermoses remain leak-free if not shaken about, which means left in an upright position, as their cap and lid designs are poorly made. If you use your thermos in the outdoor, go for one that is leak-proof from all angles.
