The inner wall, which comes into contact with the drink, is made of metal or glass. • Children who are preparing for examinations often notice that they want to keep few cups of tea in the bottle late in the night to drink. Next, the heat flow from the container sides is zero when the best thermal material are used, because reflective vacuum may not pass through heat.

- In terms of outright heat-holding performance for up to 8 hours, nothing can touch the Ultimate Series.
- A rubber disc at the base adds an extra bit of grip, making it that much less likely to slip over, too.
- Three different modes of heat transfer such as conduction, conviction and radiation transfer.
We found it a bit difficult to screw the regular stopper in properly. Keep an eye out for the best Hydro Flask deals to take the price down. Thermos flasks are insulated containers made of stainless steel. They keep drinks hot or cold by trapping air between two layers of stainless steel. This insulation prevents heat from escaping or entering the flask.

It’s a good value flask with solid all-round performance, finishing a respectable sixth overall in our temperature test. It’s relatively lightweight and the slim design slips easily into a pack. Despite the ‘pouring spout’, we noted that pouring can be a bit slow and splashy if you don’t completely remove the stopper. The mouth of the flask is also quite narrow, while the integrated cup is quite small. This is a robust and durable bit of kit for even the most demanding conditions.

It punched above its weight in our temperature test, being beaten only by the Thermos Ultimate Series 500ml and the two larger capacity flasks from Sigg and Klean Kanteen. All in all, it’s a versatile option for a multitude of everyday and outdoor uses. The only design drawback is the flask’s narrow neck and mouth, which minimises heat loss but makes cleaning a little tricky. Overall, both thermos flasks and vacuum flasks have their pros and cons. If you are looking for a durable, affordable option, a thermos flask is a good choice.
The intrepid insulator: Thermos Ultimate Flask
The lightweight build means that even when it’s full to the brim of your favourite beverage, it won’t weigh you down. What’s more, it’s packed with features which we wished we saw more of. There’s a flexible carrying handle that not only increases portability but makes unscrewing the lid incredibly easy thanks to the extra purchase it provides. There’s also an extra-wide mouth, which is especially useful if you’re using it for cold drinks – you’ll be able to quickly and easy drop iceberg-sized ice cubes into this flask. The extra-wide mouth also makes it wonderfully easy to clean.
