Comparison High Peak Tulsa vs RedPoint Airlight

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.

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).

According to the density of the filler, a general conclusion can be drawn about the strength, weight and level of thermal insulation of the tourist rug. With an increase in the density of the filler, the resistance of the tourist rug to mechanical wear increases, but at the same time, the mass of the product increases. Also, rugs with a denser filler have worse thermal insulation — this is due to the structure of the filler itself, because the lower its density, the more air-filled cells that limit heat loss. To simplify: high density — higher strength, but worse heat retention; low density — lower strength, but better heat retention. In general, the density directly depends on the type of filler. So, for foamed polyethylene and ethylene vinyl acetate, it can be 25-70 kg / m³, but the density of polyurethane foam is usually 12-40 kg / m³.

Minor repair kit, originally supplied with the mat. This option is found exclusively among inflatable and self-inflating models: even a slight damage to the shell can completely render such a rug unusable. In such cases, a repair kit allows you to correct the situation: such a kit includes at least patches (with special glue or self-adhesive ones), and sometimes additional tools. Note that repair kits are usually designed for minor damage — cuts and punctures up to 10 – 15 cm in size; however, more serious "accidents" do not happen so often.

The dimensions of the rug in the unfolded position. This parameter allows you to evaluate how much the area of the product will be enough for your purposes, and whether it will fit in the intended location — for example, in a tent.

Each individual size has its own specifics. So, choosing a classic rug (see "Type") in length depends on the height of the user, in width — taking into account the physique ( wide tourist rugs will be a burden for the average person, and narrow ones will be uncomfortable for large people). Among the seats, the situation is simpler, they all have approximately the same size, sufficient for their intended use. The thickness, usually, characterizes the softness of the product: the larger it is, the better the mat smooths out irregularities and the more pleasant it is to lie on it (ceteris paribus, of course). On the other hand, for a thick rug it is more difficult to achieve compactness when folded, so an increase in thickness affects either the dimensions of the product during transportation or the price.

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.
