Always Think About...

  • The material of the flask that can determine the durability of the flask and its heat retention. While there are plastic flasks, stainless steel materials are the best for durability and temperature retention. Plastic material will especially cool down hot contents, but a stainless steel flask is best at retaining the heat.
  • Capacity, depending on how long you need to use the flask. Some flasks can accommodate up to 1.2 litres of a drink, while others are low capacity. If you need to carry a lot of drinking contents, you need to consider getting a flask with large capacity.
  • Temperature retention capabilities, for both hot and cold drinks. Think about how long you will be needing the drink to stay hot or cold. For long working schedules, you will need a flask that can retain temperatures for long hours, possibly more than 8 hours. The longer the flask can retain your desired drink’s temperature, the better it will serve you.

While thinking about temperature retention, consider other added advantages like a cool surface when the flask has hot liquids and a sweat-proof design for keeping it dry when filled with cold drinks. If you find all the features you’re looking for, you will easily get the perfect flask for your drinks.
