How to choose a cooler bag?

Cooler bag is a heat-insulated bag or container. Some models have a cooling device, thanks to which products will remain fresh for the required time (usually up to 24 hours).

Dr. models keep the temperature inside with a cold accumulator. The battery for an isometric bag is a plastic container filled with a special solution. Before using it for 9-12 hours, put it in the freezer. Often cold batteries are already included in the bag.

Isometric bag is chosen according to several criteria.

The volume of the thermo bag is up to 180 liters with a weight of 300 g to 15 kg. For people who travel on foot, the ideal option would be a bag with a capacity of 3 liters and a weight of 400 g. Such a model will maintain a suitable temperature for 5 hours. If you use cold batteries, the time will last up to 12 hours.

If you have a car, you can choose a cooler bag large enough and powered by a cigarette lighter. Such models are connected to the cigarette lighter, and the heat from the products is removed outside, dissipating it with a cooler. The degree of cooling depends on the ambient temperature, and the temperature difference in the bag and outside does not exceed 20 degrees. There are also compressor auto-refrigerators, which are able to freeze products up to - 20 degrees.

As a rule, manufacturers make isometric bags of durable synthetic fabrics that repel water and sunlight. The outer part is made of polyester, nylon and polyvinyl chloride. When choosing a cooler bag, pay attention to the inside, where cold batteries and food are located. It so happens that manufacturers are trying to save on internal materials, using ordinary colored polyethylene, and not durable PVC.

Some models are made of high-strength plastic and have several layers, thanks to which products retain their freshness for up to a day. Before buying, pay attention to the thickness of the walls of the thermo bag. Feel it. If the inner insulation layer is not felt, it is better to discard such a device, since it will quickly heat up.

Car isometric bags must have built-in locks and handles that will reliably protect against arbitrary opening. Mobile devices should have special comfortable carrying handles, soft padding for the shoulder, wheels and adjustable straps.

When buying, pay attention to the manufacturer and the warranty period. It is better to give preference to well-known brands that specialize in the manufacture of such products. Many manufacturers give a guarantee for thermo bags from 3 to 5 years.
