What is the Best Thermos Flask? UK Vacuum Flask Reviews

Flasks are exceptionally useful when you are out hiking or camping, especially in the winter months. They are there to keep your coffee and soup nice and warm so that you can enjoy it when you finally get a moment to rest. Of course, it’s not always easy to find the right one. In this guide, we have gathered thermos flask reviews in order to find the best thermos flask or best vacuum flask for you. Take a look and see if the one for you is listed here.

How to Choose a Flask

There is a huge range of flasks available for purchase, so it’s not always easy to decide which one is going to be right for you. In this section, we give some advice about choosing the right flask for you, as well as a few things to look for in the next one. All of this will help narrow down your search for the perfect thermos flask.

The first thing you need to do is ask yourself what purpose the thermos flask will serve. Are you planning on taking it with you when you go hiking or camping? Do you want hot food and drinks on your trip or are you not bothered by it? Answering these questions is important when it comes to moving on and finding the right flask.

Is the thermos for food or beverages? This is important because the thermos for each purpose is different. Those that were designed for foods, like soup, have a very large mouth so that it is easier to pour into the lid or a bowl. The thermos for tea and coffee (as well as other hot beverages) has a much narrower neck to control the flow of liquid when you go to pour.

You should also look at the material a flask is made from. Plastic is the worst material and should be avoided. It does not do well when it comes to retaining heat, and it is also very fragile which makes it tricky to carry around. Metal is the best material, and the most commonly used, namely stainless steel. The inside chamber is sometimes made of glass because it is more hygienic and easier to clean.

You should always check out the reviews for the flask you are looking to purchase. They can tell you a lot about a product and its overall quality, giving you good insight before you buy. While expensive flasks are often more durable and reliable than the cheaper ones, this is not always the case, and so the reviews can come in very handy. Look at the quality and not the price tag.

Things to Look for

When you go to purchase your thermos flask, there are a few things you should bear in mind. The first of these is the volume. If you don’t plan on sharing with a group of people, then it is often worth going for the smaller sizes because they are easier to carry around with you and you will be able to get through the serving better. For sharing with large groups, the larger volume models are suggested.

The cap is also very important. Many people forget to check how efficient the cap is when you close it. Ideally, it will fully close and lock the heat into the thermos flask without any being lost. Ones that are sealed with a cork are not recommended as the seal is insecure and can cause leakages. Screw caps are the best option because they are incredibly secure and provide a tight seal.

The Advantages of a Flask

Here are a few of the benefits to using a thermos flask on your hikes and treks.

  • Keeps your food and drink hot all day
  • Keeps the liquid contents secure in your bag with no leakages
  • They are durable and safe to use
  • They can even keep your water cold for up to 24 hours
  • Help you to stay hydrated while you are on the move
  • Ideal for sharing with others in your group

All that’s left is to choose the perfect one for you. Take a look at our thermos flask reviews for some of our favourite models.
