The best thermoses with a capacity of 1 liter

Thermos of the Ukrainian brand Terra Incognita is made of food grade 18/8 stainless steel. Plus, the beige and gray versions have a powder coating on the outer walls, which creates a laconic matte surface and additional protection from scratches. Also note that in addition to different color variations, a related 1.2 l model is also available for sale - Duett 1200.

The thermos is made using vacuum insulation technology - there is a hermetic layer between the metal walls. Thanks to this design, the model maintains the initial temperature well. For example, factory tests show that boiling water cools down slowly: after 6 hours - to 86 degrees, after 12 hours - to 77, and after 24 hours the liquid will still be hot - about 62 °C.

The container is hermetically sealed with a blind screw cap. It is supplemented with grooves, thanks to which drinks can be poured into cups by partially unscrewing, rather than completely. This saves time and reduces heat loss.

The outer lid is traditionally ready to serve as a container for drinking drinks (200 ml). In addition, the set also includes a second mug of a slightly smaller size (190 ml): both have a heat-insulating design so as not to burn your hands and lips.

Terra Incognita Duett 1000 is a good thermos for reasonable money.

The Thermos brand liter thermos differs from its analogues by its narrow form factor. Thus, with a height of 32 cm, the model has a small base diameter of 8 cm. Thanks to this feature, Thermos PLF-1000 easily fits into any side pocket of a city backpack or school bag, and is also compatible with many car cup holders (and this feature is more typical of thermo mugs).

The thermos also has a silicone ring on the lid: it acts as a handle for carrying, and when not needed, it is recessed into the body. There is a plastic pad on the base of the product, thanks to which the model should stand firmly on various surfaces. Separately, it is worth highlighting the screw cap with a partial unscrewing function for pouring drinks.

Structurally, the thermos has an outer layer and a stainless steel flask, and a vacuum layer is located between them. The manufacturer claims that the cold inside can be maintained for at least 12 hours, and the heat - about 8 hours. In practice, when pouring boiling water in the morning, the contents, as a rule, remain quite hot even in the evening.

Other features include the matte outer coating, which should preserve the product's appearance longer and prevent scratches. By the way, the narrow form factor also makes the diameter of the flask's neck smaller: this complicates the maintenance procedure somewhat and is one of the model's shortcomings. Otherwise, the Thermos PLF-1000 is a stylish and practical thermos from a well-known manufacturer.

In the Esbit brand line, Vacuum Flask thermoses are positioned as classic solutions. The liter model is made of stainless steel and does not provide for additional external coating, unlike the related version Esbit Stainless Steel.

The thermos flask is also made of stainless steel - food grade 18/8 is used. And the lids and other components do not contain potentially hazardous components - BPA and phthalates.

The model is designed for use with hot and cold drinks. The double-walled design and oblong shape (275x90 mm) help maintain the original temperature for a long time. In the case of boiling water, even after a day the contents will still be quite hot (about 60 degrees Celsius). At shorter time intervals, the situation is as follows: 85 °C after 6 hours and 75 °C after 12 hours.

Two people can drink drinks without additional utensils, as there is an external mug lid and another plastic cup included.

Another advantage of the thermos is that it has two lids. The first is a valve with a pouring button, which is convenient to use with one hand. There is also a blind screw cap: it can be a spare and/or useful for drinks with additives (for easy subsequent care).

Esbit Vacuum Flask 1.0 is an interesting liter thermos with an adequate price tag and an extended delivery set.

The specialized manufacturer of thermoses Zojirushi recommends the SJ-JS10 model for maintaining the temperature of drinks for a long time. It can be considered a liter one, because the total capacity is only slightly larger - 1030 ml. By the way, compared to its analogues, it is slightly lighter without contents - 400 grams.

Thanks to the vacuum insulation technology, the heat inside will be retained for at least a day - after 6 hours, boiling water will cool down to only 82 degrees Celsius, and after 24 hours - to 62 °C. In the case of soft drinks, the situation is even better - the contents with an initial temperature of 4 °C in 6 hours heat up by only 3 degrees, that is, it remains very cold.

Zojirushi SJ-JS10 is made of 18/8 stainless steel. The outer metal walls effectively protect against impacts or falls. Inside, the flask has additional protection against oxidation - a special two-layer coating is used, thanks to which you can safely pour sports drinks into the thermos (for example, isotonic, protein shakes, etc.).

The outer lid is ready to act as a cup as usual. Under it is a practical valve with a push-button opening for easy pouring of the contents. This lid is made of plastic, which does not contain bisphenol A or other potentially harmful components.

The model's long service life is confirmed by a 5-year warranty on insulation properties. All this, together with the brand's legendary status, makes the Zojirushi SJ-JS10 an excellent choice for a variety of scenarios, including tourism, sports, and everyday use.

The famous American brand Stanley is so confident in the high quality of the Classic Legendary thermos that it provides a lifetime warranty (according to other sources, the warranty period is 25 years).

The thermos has a memorable appearance with a characteristic narrowing closer to the top of the body. The top is crowned with a lid to match stainless steel, which also serves as a mug with a capacity of 250 ml. The body of the model is also steel, but unlike the lid, it can be painted green, blue or black. The paint is not afraid of damage, and the body is also not afraid of falls.

The model has a folding handle on the side, which adds convenience when carrying the thermos. It has one minor drawback - when unfolded, the handle rattles against the body. You can also hold on to the body of the model - double vacuum insulation of the walls of the body eliminates changes in its temperature regardless of the type of drink poured in.

The long time the liquid temperature is maintained inside the stainless steel flask deserves special respect. Real measurements showed that boiling water cools down to about 60°C after 24 hours, and to 80°C after 12 hours. That is, the owner of the thermos will be able to taste something hot a day after filling it, and you can brew tea in the model even after half a day.

It is highly recommended not to wash the thermos in the dishwasher, as this may lead to a breach of the seal of the structure. Stanley Classic Legendary does not require any other handling rules, so the high cost of the model pales in comparison with its declared characteristics. With adequate handling, the thermos will serve its owner for a long period of time in almost any situation.
