The car allows you to take everything you need for recreation on the road: tents, camping mats, folding chairs, badminton rackets, and a soccer ball. And also, of course, containers with provisions.
When a long trip into nature is planned, many drivers prefer to pack pre-prepared food in a thermal box or cooler bag — this eliminates the need to eat cold dishes or heat them over an open fire. However, not every such bag can boast decent quality, so its selection should be approached with all seriousness.
What to pay attention to when choosing the size and checking quality?
First of all, when going shopping, it is worth deciding how exactly the thermal bag is planned to be used. The volume of such products can range from four to fifty liters! Naturally, if the bag will be used by only two or three people, and only during short trips out of town, there is no point in purchasing a bulky and expensive model. If you are used to traveling by car over long distances in the company of friends, you should not save — a compact thermal bag will clearly not be enough in such a situation.
The second important aspect to evaluate when choosing a bag is the properties of the material and the neatness of the stitching. Maintaining the required temperature inside is ensured by a special inner layer. A dense layer of polyvinyl chloride reflects light and prevents the leakage of heat or cold. Therefore, if you notice that this layer is too thin or attached carelessly, it is worth doubting the reliability of such a product.
When choosing a thermal bag, do not be lazy to carefully inspect it both outside and inside, and also thoroughly feel the fabric. When ordering through an online store, you will have to judge the quality from photos — however, you can examine the purchase in detail after receiving it.
Cold accumulator — a necessary addition to a thermal bag
Even the most solid thermal bag is not capable of maintaining cold for many hours in a row — after all, it has to be periodically opened, letting warm air inside. That is why cooler bags, as a rule, use additional cold accumulators.
Such a device looks like a small plastic container filled with a solution with high heat capacity. Without an accumulator, a thermal bag can hold cold for about 12 hours, but with its use, this period doubles. Thus, the accumulator will be very useful if you are planning a trip with an overnight stay or even for several days.
