It's really worth investing in a decent thermos. Warm coffee after 6 hours hits the spot much better than lukewarm. It keeps the heat well. It's great that there are two caps included and it's nice to have the option to pour into two cups. And the texture of the paint is very pleasant. It feels good to hold. The larger size is only a plus, as it doesn't take up much more space and you can share with someone.

A very good thermos; I wasn’t expecting anything special, but it turned out to be quite good equipment. From my own experience, I knew not to use those click-type stoppers, and it was a hugely positive feeling when I received both versions of the caps in the box and could choose for myself.

Great thermos! If I first pour boiling water into it to warm it up, then pour that boiling water out and brew the intended drink in it, such as tea or coffee, the thermos keeps the temperature of that drink for a veery long time. After doing an experiment—tea prepared in the way described above was still nicely warm even after two days. I recommend it👍🏼

Over the years, this is already the fourth 1-liter thermos from this brand. Always the same model, just different colors. I once tested it by measuring the temperature of the liquid inside, and at a lower ambient temperature it showed higher temperatures over time than described. In general, I used only the screw cap, not the "click" one.

I bought two 1-liter models for myself. + The rough-textured paint makes it easier to hold + Two cups included in the set is an absolutely fantastic idea + Two different stoppers included in the set - same as above + For professional drivers, manual workers, and office workers, it is an ideal solution to have access to a chilled or hot drink + It keeps the drink satisfactorily warm for a full 10 hours in 18 degrees Celsius conditions. I am curious how it will perform during winter. - There is no thermal-insulating "foot" on the bottom (for example, a 1.5 cm layer of rubber or dense foam); it would be useful to increase insulation from the surroundings. Fortunately, you can make something like that yourself (which I recommend), or for example make a thermal cover for such a thermos from a fleece sleeve, thanks to which its contents will be additionally insulated from the cold : ) I gave it 4 stars because of the lack of additional insulation on the bottom. Other than that: a really good thermos from an honestly mid-range quality tier.

It keeps the temperature perfectly during trips. I bought the green one, I have to admit it was on sale. The color doesn't matter, it does the job. I use it for everyday work because nobody wants to make coffee for workers anymore.

I highly recommend, very nice thermos! I was considering a larger capacity but 0.7 liters of coffee or tea is definitely enough for a few good hours. Nothing leaks, huge plus, and the build quality is great.

I chose this thermos for work and trips because the capacity of 0.75 l is ideal for me: it's not too small, and at the same time not as big as the one-litre model. It keeps the temperature at a good level – in the morning I pour in tea and after a few hours it's still very warm. The Olive Green colour is practical, the thermos looks good and small scratches are not visible on it. There is one detail: when filling with boiling water, the first sips may be too hot, so I usually let the drink cool down a bit. After sweet drinks, it's worth rinsing the thermos immediately to get rid of the smell. To sum up – a simple, solid thermos that is worth its price.

Great thermal bottle, perfectly fulfilling its main role, which is to keep beverages at the right temperature. The outer coating may feel a bit 'sticky', but it provides a solid grip in the hand. It is very functional thanks to the presence of two cups and a double locking system.

I considered a thermos from another company. I chose ESBIT because of other products from this company. As usual, I was not disappointed. I use the thermos every day in various field situations (forests, training grounds). It works great and keeps the heat very well! Hot coffee/tea/water is perfect.

Very good quality equipment for really little money. The thermos set includes two cups and two different stoppers. This is my next product from Esbit and definitely not the last one. Very good workmanship, works even better than you might expect and has never had any problems.

I wholeheartedly recommend this thermos. When it was -8 degrees outside, after 7 hours the tea was still hot, and even after 24 hours it was still warm. Additionally, the two cups are a big advantage.

Thermos tested in the field. With an outside temperature a few degrees above 0°C, the tea was still lukewarm after 24 hours. After 12 hours, it was very warm (the assessment of the temperature is quite subjective). At -7°C, after 5 hours in the field, the tea was hot. The best thermos I have owned so far. Extra point for the double cup.

We were looking for a new thermos because my previous one didn't keep heat long enough, which always irritated me. The most important thing for us was that the tea stayed hot as long as possible. Now the problem is solved, and additionally, the thermos in Olive Green looks excellent.

Very nice, solid, and spacious thermos. It has quite a large circumference, so you need to make room for it in your backpack, but it works perfectly. It keeps heat for a very long time.
