The main task of a thermos is the long-term preservation of cold or heat. In order not to purchase a fake or low-quality product, I will tell you how to choose the right thermos.

Thermos is an excellent invention that makes life easier. He is taken on trips and business trips, for work and nature.

A trip to nature or a walk in the forest will not bring joy without a thermos in a backpack. To take kettle and making tea on fire doesn’t always work.

Before going to the store, decide for what purpose you get a thermos. If used for storing drinks, pay attention to models with a narrow neck. For products, the wide-neck option is suitable.

  1. Bullet model. Great for storing liquids. The model is elongated, with a removable lid-glass and a cover with a convenient strap.
  2. Pomp. It is not intended for carrying, stationary option. Keeps liquid temperature for a long time. To pour cool or hot liquid into a mug, just press the mechanical button, you do not need to remove the lid.
  3. Thermo mug. If you are driving for a long time, and on the road like to taste a cup of hot tea, for example, puer, pay attention to the thermomug. The device keeps the temperature for several hours.
  4. Universal model. Suitable for storing food and liquids. In most cases, it has a double plug, which ensures perfect tightness. It is equipped with a folding handle, and the lid can be used as a mug.
  5. Sudkovy. The composition includes several capacious containers that are tightly closed. Despite the large size, it is lightweight. Not surprising, because the containers are made of plastic.
  6. Thermal bag. The invention is used for storing food at home. The main disadvantage is the short temperature retention.

Cases are made of plastic or metal. If you want to take a thermos on the road, buy a model with a metal case. If home use is intended, a plastic case will do. In addition, the cost of the plastic option is lower than the metal one.

It is useful to pay attention to the material of the flask. In most cases, the flask is made of steel, glass or plastic. Glass flasks retain heat well, but are very fragile. If you like a metal flask, opt for a stainless version. Minus a steel flask - the remains of food stick to the walls and traces of liquid remain.

The most convenient is a plastic flask that is lightweight and not afraid of bumps. However, plastic easily absorbs odors and dyes, which affects the taste of food stored in a thermos.

If you have chosen a specific model, make sure that the cork is tightly closed and smell the smell. If the smell is unpleasant, the product is made of cheap material.

If you buy a thermos for food, you can bring to work the warmth, aroma and taste of homemade food.

  1. First of all, pay attention to the ability to keep warm. On modern products it is written for food that this period of time reaches 8 hours. The time of heat storage is affected by the tightness and type of flask.
  2. Flasks are made of metal or glass. Both options hold heat well.
  3. Food thermoses that are equipped with a compact ship and a plastic insert retain heat for 4 hours due to poor tightness.
  4. If you like hot soups, pay attention to the models, which are based on an all-metal flask. In some cases, they are equipped with containers and ships.
  5. Options without containers are usually available in volumes of 0.5 liters. For an adult, such a product is not suitable. For the child just right.

How to choose a good thermos for fishing

As practice shows, it is not worth reinsurance in a question. If you ride catch pike or crucified alone, it makes no sense to buy a large-volume product. As a result, the question arises: how to choose a thermos for fishing so that it meets the needs?

The choice comes down to the main characteristics - volume, material, neck width and cork. Let's consider each item in more detail.

  1. Volume. Capacity directly affects the ability to retain heat for a long time. My friends use a one and a half liter thermos, because: they fish alone, the average fishing time does not exceed 6 hours, the product is compact and does not take up much space in a backpack. If the characteristics of your fishing are similar, listen to the tips. Otherwise, buy a larger thermos.
  2. Flask material. Flasks are made of metal or glass. Each species has its own advantages and disadvantages. In particular, a glass bulb is fragile, while a metal one may be depressurized.
  3. Neck width. A great option for fishing is a 1.5-liter stainless steel thermos with a wide neck and a double stopper. To get hot tea, a small cork is taken out, and a large one for washing. The wide-neck option is more convenient, but the contents cool much faster and leakage problems can occur over time.
  4. Cork with key. Many people like these products - it’s convenient and beautiful. However, the cork has a complex structure and may fail.
  5. Screw caps. They are highly reliable because they are equipped with an insulating gasket.
  6. Cork tree. If the cork is made of quality material, it will last a long time. Otherwise, it will become a headache.

I hope I managed to answer the question of how to choose a thermos for fishing. Do not forget about your needs and tastes. If they differ from the tips reviewed, make changes to the selection algorithm.
