Thermos flask: for hot and cold drinks

If you like to drink your beverages well chilled or nice and hot, even during a long tour, you need a well-insulated thermos bottle, also known as a thermos flask, insulated bottle, or insulated jug. You can use it to carry your beverages safely and always at the right temperature.

Thermos flasks come in many sizes and varieties, so you can choose the right model for your outdoor activity. Small and large thermos flasks, as well as models that can also be used as insulated food containers, allow you to take your favorite drinks and food with you on outdoor trips.

Thermos flask: practical for on the go

Without a thermos flask, drinks quickly lose their optimal drinking temperature. Whether it's morning coffee, tea, or cold juice spritzer for a hot summer day—without the right thermos flask, these drinks won't taste good after a short time. To keep your drinks at the optimal temperature, a thermos flask must meet various criteria.

You can recognize a good thermos bottle by the following features:

  • It is lightweight and does not weigh down your luggage unnecessarily.
  • It comes in different sizes, so you can take the right one with you for short or longer trips.
  • The material (e.g., stainless steel) is rustproof, break-proof, leak-proof, and robust.
  • The cap of the insulated bottle can be screwed on tightly to ensure that no liquid leaks out. With many models, you can also open the cap easily with just one hand.
  • Ideally, the thermos flask should be double-walled and vacuum-insulated so that drinks stay warm or cold for a long time. Good thermos flasks keep their contents warm or cold for at least six to twelve hours.
  • The outer material should be as non-slip as possible so that it does not slip out of your hand easily.
  • Many models have a lid that can also be used as a drinking cup. This allows you to comfortably drink from the cup while on the go.
  • The closure stopper often has a practical pouring opening so that it does not have to be opened completely and less heat is lost.
  • Some models have an extra-wide opening so that you can also use them to fill with hot meals (e.g., soups and stews). Here, too, you can use the lid as a bowl for eating.
  • The thermos flask is easy to clean. Some models are even dishwasher safe.
  • It is also free of toxins and tasteless.

Perfect for all outdoor activities

The good insulating effect of a thermos bottle (or thermos flask, vacuum flask) is due to its design. It usually consists of a double-walled container, so that the temperature inside can be maintained for a very long time. The thermos bottle is break-resistant because it does not use glass, but instead uses robust stainless steel material. You can use it when camping, but also on trekking tours, as well as in the office or at university. Wherever you want to take your drinks with you, they will be kept optimally cool or warm in an insulated bottle.
