The container is isothermal The container is isothermal
For the experiment, we purchased three cooler bags (two original and cheap Chinese ones, as well as a cool and expensive one from Germany), and in addition, a rigid isothermal container (French!) And a picnic set, which allows not only to save drinks and snacks, but also culturally use them in nature. Also, naturally, Chinese.
As an experimental product, we chose drinking water in plastic 1.5-liter bottles. As recommended by the manufacturers of bags, they kept it in a stationary refrigerator. In the freezer compartment at the same time isothermal containers were frozen - two per bag, each with a volume of 0.3 l. The temperature was measured both in the bags themselves and directly in the bottles - before and after the experiment, which lasted the whole summer working day.
We start, like on a picnic, at eight in the morning: during the night, the water in the refrigerator cooled to + 7 Β° C, and the containers froze to -12 Β° C. All bags were loaded into the black Getz interior, set out in the sun. Here in the cabin already at 35 Β° β¦ Six hours have passed. That's all, we βcame to the beachβ, βswamβ, now you can drink (water!) And have a bite. How many degrees are there in bottles and about βsandwichesβ? Now let's see β¦ The answer is in the captions to the photo.

A cheerful pattern, a bargain price β¦ It is curious that the bag kept the water more or less cold. Honestly, they thought it would be worse.

There are several external pockets. They promise to maintain a temperature of + 5 Β° C for 14 hours. However, already at the end of the working day there was more than 12 Β° C. But this result is one of the best. A little expensive, but the largest volume.

It has an additional thermally insulated pocket on the outside and two thermally insulated cup holders for bottles. The water in it was heated only 4 Β° C during the day, but the cold-loving products would have been capricious.

It has an external pocket with a set of dishes for four, as well as a corkscrew. Although the manufacturer, generally speaking, did not say anything about freshness, efficiency is the best. That's just the volume is small.

Capacious hard container unexpectedly lost. Alas, there is no thermal insulation in the plastic lid; it is simply blown and even leaky.
