A faithful companion for hikers, fishermen, and hunters, a reliable keeper of hot and cold drinks and food, and extremely low-maintenance – all of this describes a type of Dewar flask. Or, simply, a thermos.
With so many options available, choosing a quality thermos that will keep hot things hot and cold things cold for as long as possible can be a challenging task.
10. Hangzhou EXCO Industrial MC180 (1.8 l)
- body material: plastic
- flask material: glass
- Features: handle on the body, cup-shaped lid
- weight: 875 g
The cheapest option on our list of thermoses that retain temperature better. But in this case, "cheap" doesn't equate to "low-quality.".
This Chinese product has a convenient handle so you don't have to press your hand to the thermos body, holds almost 2 liters, and retains heat for 8 hours. What more could you want from such a thermos?

- Features: vacuum, cup-shaped lid
- dimensions: 29 x 7.50 cm
- weight: 490 g
According to "Marka Kachestva," the domestic brand Amet has the best recognition on the market. And it's hard to argue with that; even the author of this article owns an Amet thermos, which has served him faithfully for several years.
The Amet Premier KN is the perfect choice for commuting to work or school. It's made of durable, thick steel, maintains heat for the manufacturer's stated 6 hours or even longer (up to 12 hours), has a tightly screwed lid, and stays cool. And it's quite affordable.

- body material: steel
- retains heat for up to 24 hours
- keeps cold for up to 12 hours
- dimensions: 29.50 x 10 cm

This thermos from a Japanese brand (made in Thailand) features a handle and a removable strap for easy carrying. It's quite compact for its size and is odorless.
The advantages of using Zojirushi SJ-SD12 also include:
- wide neck,
- long heat retention time,
- a hermetically sealed lid with a convenient opening button,
- as well as a presentable appearance.
The flask's Teflon coating makes it easy to clean and prevents the beverage from coming into contact with metal, preserving its flavor. So, if you're wondering which thermos to buy but don't like Chinese models, we recommend the Zojirushi SJ-SD12.
Pros: light weight, holds heat exactly as stated by the manufacturer, Teflon coating of the flask (however, this can also be considered a disadvantage - more on that below), reliable construction.

6. STANLEY Classic
- body material: steel
- flask material: steel
- retains heat for up to 20 hours
- keeps cold for up to 20 hours
- Features: vacuum, cup-shaped lid
- dimensions: 29.80 x 8.90 cm
This model has a classic design with a small opening and a cup-like lid. On the one hand, this means you don't have to carry around an extra container for hot tea or coffee. On the other hand, drinking on the go can be difficult, just like in a moving car. To do this, you need to find a place to place the cup-like lid, then pour the drink into it through the small neck of the thermos.
But this inconvenience is accompanied by exceptional insulation of both hot and cold drinks.
One of the advantages of STANLEY thermoses is their high impact resistance. While you're unlikely to hit or kick the thermos, the possibility of it accidentally falling over isn't out of the question.
The STANLEY Classic is made of wear-resistant steel and plastic elements, which make the frame lightweight and resistant to cracking at high temperatures. It's also dishwasher safe.
Pros: beautiful, comfortable, well made.
Cons: the price is slightly higher than similar models.

This thermos is so attractive that it's a perfect gift. It's very comfortable to use and has a convenient strap for carrying or hanging, for example, from a backpack.
The Zoku lid closes with a satisfying click. When you hear this sound, it means the lid is completely closed, ensuring you won't lose a drop of what's inside.

Cons: costs more than similar products.

Therefore, users recommend filling the Thermos JNL-350 at a comfortable temperature.
Pros: the body doesn't get dirty too easily, it's comfortable for a child, and it's a great option for car trips (when you need to quickly open the thermos with one hand). It retains heat perfectly.
