Weight
The weight of a tourist rug depends both on the materials of manufacture and on the geometric parameters, type (inflatable or self-inflating) and the purpose of the model. It can increase due to the presence of an additional thermal insulating layer based on aluminium foil, etc. Note that this parameter is of priority when transporting on oneself (on foot, especially in difficult conditions) — for such cases, models with a
minimum weight are best suited. In situations of tourism in transport, or going out into nature, the convenience of the product will play a greater role than its weight.
Qty. valves
The number of valves for inflating and releasing air provided in the design of an inflatable or self-inflating product (see "Type").
— 1. One valve used for both inflating and deflating the mat. The advantages of this option are simplicity and low cost. On the other hand, the throughput of valves is in most cases low; this is not a serious disadvantage when filling the mat with air, but can greatly slow down the folding.
— 2. The features of this option depend on the number of seats (see above) for which a certain model of the rug is designed. So, in single equipment each valve has its own specialization. One is designed to inflate and is often designed to prevent air from escaping even when the plug is open; the other, which is responsible for the release of air, has a high throughput and allows you to quickly blow off and roll up the product. However such models cost more than similar single-valve ones. And double mats usually consist of two separate halves, each of which provides its own universal valve; in terms of inflation / deflation, they are no different from the single-valve models described above.
- 4. Four valves can be installed in two-seat models: each separate half of these mats has an inlet and outlet valve, similar to single-seat two-valve products (see above).
Dimensions (folded)
Dimensions of the rug when folded. This parameter determines how much space the product will take up during transportation. Note that in this case, “perfect” sizes are usually indicated, corresponding to the most dense packaging according to all the rules; actual dimensions may be slightly larger, depending on the quality of folding.
