The presence of a
bedding or karemat in the kit. Bedding in this case is a dense blanket made of wool, fleece or other similar material, suitable for laying on the ground. Karemat, in turn, is a tourist rug made of foamed polymer.
Both of these products have a common purpose: they protect the person sitting on the ground from pollution and, to a certain extent, from the cold. However, they differ markedly in materials and application features. In general, bedding is considered more convenient for picnics, and it is they that are most often included in the package. This is due to the fact that, when unfolded, the bedding can be several square metres in size, which allows you to arrange rather large-scale “gatherings” in nature by organizing a “table” right on the bedspread. And for carrying and storage, such a blanket is folded into a compact bale. The karemat, in turn, when folded, is similar in size to the bedding, but when unfolded, it is much inferior to it: the size of such a rug is usually comparable to a sleeping place for one person, and in some cases it is even smaller. Therefore, mats have not received much popularity in picnic sets. However they provide a better degree of thermal insulation than bedding; however, sit-on-the-ground picnics are rarely held in cold weather. In extreme cases, no one interferes with the use of additional devices with a bedspread, such as tourist "seats" made of foam, purchased separately.
The working volume of the package in which the picnic/barbecue set is supplied.
This parameter is indicated for backpacks and bags (see "Form"). The working volume usually does not mean the total volume, but the capacity of the additional pocket (see above). It determines the amount of cargo — primarily products — that can be placed in a bag or backpack in addition to the main contents (kitchen and tableware).
When choosing according to this indicator, note that an additional pocket may have a different shape — accordingly, models with the same volume may differ significantly in actual capabilities. For example, in backpacks, an additional compartment can be made flat, “on the entire back”, and it can be difficult to fit even a small melon there, while in bags this is usually not a problem.
