The 10 best thermos flasks to buy in Switzerland
The best thermos flask keeps beverages hot or cold for many hours, making it a great option for commuting, taking drinks to work, camping, hiking, and much more. However, many flasks are low quality and will not maintain the optimal temperature for long, so it helps to know what to look for to ensure you get the best thermos.
Check out the buying guide below for all the information you need to know to find the best thermos flasks:
What are thermos flasks?
A thermos flask, also called a vacuum flask, is a container designed to keep beverages hot or cold for prolonged periods. The design features an interior and exterior flask, with the double insulation creating a vacuumed atmosphere that maintains the beverage’s temperature by reducing heat loss.
Why should you buy a good thermos flask?
The best thermos flasks keep drinks hot for many hours, making it a great buy for anyone that enjoys coffee, tea, and other hot beverages. It can also maintain colder temperatures in drinks, preventing them from reaching room temperature, so it’s ideal for anyone that enjoys a refreshing cold drink. Being able to keep drinks both hot and cold makes a vacuum flask a great buy for many situations, such as taking drinks to work, outdoor excursions, or even just sitting in the house.
How to choose the right thermos flask in 2025?
Here are some things to consider when looking for the best vacuum flask:
- Size: Flasks comes volume capacities ranging from 500ml to several litres, so you’ll want to consider how liquid it holds, choosing something that meets your daily needs. A large flask is great for people that drink lots of hot drinks throughout the day, such as taking a large flash of coffee to your work, while it’s useful for sharing. Smaller flasks have lower capacity but are lighter to carry and still great for individual use.
- Materials: While the best thermos flasks are made from metals like stainless steel, some are made from glass. Providing it has the double insulation design, glass flasks can be just as good as their metal counterparts and provide a nice view of the drink inside, although they aren’t as durable and could break if you drop it.
- Heat Retention: Always check how long the flask retains heat for, as some are better at this than others. Cheaper flasks tend to retain heat for 2-5 hours, while the best flasks can retain heat for upwards of 12 hours, although these will cost more and may not be necessary if you’re going to drink it sooner rather than later.
