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.
Esbit Vacuum Flask 500 ml - Olive Green
Spacious 0.5l vacuum flask crafted from stainless steel provides ample capacity to carry enough warming beverages for a full day for an adult. The Olive Green matte finish with anti-slip texture guarantees a firm grip, even with thick gloves on. Owing to its generous volume and lightweight design, the flask is ideal for responsible guardians, rescuers, or group leaders who need to supply others as well!
An essential companion for chilly days on hiking trails, ski slopes, outdoor work, or long hours of fishing. Engineered to keep drinks cold just as efficiently as it preserves heat, the flask easily stores both refreshing and isotonic beverages. Versatility ensures reliable warmth and energy in winter, while in summer, it provides essential hydration and refreshment.
Two cups
The flask is equipped with a secondary cup (positioned beneath the main cup/lid) as well as two stoppers for enhanced versatility:
- a One Touch stopper enables pouring without the need to unscrew,
- while the other uses a classic screw cap design.
Selection between the stoppers can be tailored to suit your beverage—whether it's tea, a chilled isotonic drink, or a hearty thick soup. The additional cup makes it possible for multiple users to share the warming contents simultaneously.

Engineered for superior thermal insulation performance with both hot and cold beverages, the model offers outstanding resistance to mechanical impacts.

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.
-
Thermos purchased on October 17, 2025, 16:49; delivery October 18, 2025, 07:04. Shock! Respect. P.S The thermos keeps drinks hot for a very long time—after 23 hours, the drink was still hot. I RECOMMEND MILITARIA.PL as well as the ESBIT 1l thermos.

I chose Esbit because I’ve had one of their thermoses for almost 10 years. I knew it wouldn’t let me down. Now I can have both tea and coffee at hand at the same time. It’s nice that they’ve kept up the standard, still adding two cups and two types of caps.
-
It keeps the temperature very well. After 12 hours it's still hot, after 24 hours it's still warm enough to heat up. Tested in weather: heavy rain, strong wind, about 10 degrees Celsius. The only downside is the paint, which feels nice to the touch, but after one fishing trip, where the thermos was standing on the ground, tipped over a few times, and maybe rolled a bit, it got really scuffed, the paint came off, and you can already see the silver color (probably aluminum). I give 4 stars for heat retention, minus one star for that paint.
-
The best thermos I've had so far. It keeps the temperature the whole day even in really extreme conditions. It's also great in summer if you want to keep ice cubes inside, as they don't melt for many hours even in strong sunlight.
-
It doesn't leak, keeps the temperature for a very long time, and is handy and lightweight. Two cups are a plus, though it's a pity one tends to fall out when opening. The two stoppers are also a nice feature. I recommend the product and the store. Bought it again.
-
Esbit as always is reliable. It cools well on hot days and keeps drinks warm on cold ones. The rough structure prevents light reflections if you care about concealment. Very solidly made. Simplicity and reliability. The extra cup is a big advantage. The only downside, at least in my opinion, is the size. However, it would be hard to find a thermos of this capacity in smaller dimensions. There is always some trade-off.
