Comparison Trek Planet Montana 4 vs Tramp Sphinx

— Hemisphere. Tents with a frame of two (sometimes more) crossed arches. The main advantage of such a case is good resistance to wind. On the other hand, the interior space of the hemispheres is relatively small.

— Half -shell. In cross section, the semi-barrel has the shape of a half circle (or more or less similar), and its frame consists of several semicircular arcs arranged in parallel. This provides a good internal volume, but the wind resistance of this type of hull is lower than that of hemispheres (which, however, is not critical in conditions of plains and low mountains, where there are no storm winds).

— Shatrovaya. In such a case, one rack is used, located in the middle, and the tent itself has the shape of a pyramid or cone. The advantage of tents is their high height, the disadvantage is the inconvenience due to the presence of a rack inside the living space and poor resistance to wind. This form is quite rare.

— Double. The upper part of such a body is a rib, from which two sides of the awning (slopes) diverge at an angle. To create this shape, two internal supports are usually used at the ends of the tent. This design provides additional water resistance, because. the awning is located at a large angle to the drops falling from above; at the same time, due to the inconvenience cre...ated by the supports located inside, and a number of other features, such tents are very rare.

— Cube. A hull shape found only in fishing tents (see "Intended Use"). Almost all such models are intended for winter use and ice fishing. At the same time, some of them do not have a bottom or are equipped with a hole in the bottom, which allows you to install an awning directly above the hole; others are closed from all sides, including from below, and fishing is supposed to be through the opening. However, among the cubic tents there are also demi-season/summer models, including advanced solutions for carp fishing.

The vestibule is a kind of "entrance hall" in front of the entrance to the main compartment (s) of the tent.

The specific design and purpose of such a "hallway" may be different. So, in small two-layer tents, the space between the inner and outer layers in front of the entrance plays the role of a vestibule (for this, the outer canopy is stretched at a greater angle relative to the vertical than the inner one). The dimensions of such a compartment are small, it is designed mainly for storing individual items, such as shoes. In larger models, the vestibule is made in the form of a full-fledged compartment, which differs from the main compartment only in the absence of a bottom (although there are exceptions). Such a compartment can be located between two sleeping compartments; and in some tents two vestibules are provided at once.

Anyway, such equipment increases the useful area of \u200b\u200bthe tent and provides additional comfort when using it. Tambour can be used to store equipment, often quite bulky; with an open entrance, it provides additional protection for the main volume of the tent from rain, sun and wind; and in a large vestibule(150 cm long or more), you can even organize additional sleeping places (if the weather permits) or even an auxiliary room such as a kitchen, dining room, administrative area, etc. " below.

The length of the vestibule provided in the tent.

See above for more details on the vestibule. As for its dimensions, the length of the vestibule is measured along the same side along which the length of the entire tent is measured; and the width of this compartment usually corresponds to the overall width of the tent, and it does not need to be specified separately in the specifications. At the same time, we note that due to such measurement rules, the length of the vestibule is often less than its width; this is quite normal in this case.

The specific ratio between the dimensions of this compartment in different tents may be different. However, in general, a longer vestibule is usually larger and more capacious than a shorter one. When choosing, it should be taken into account that a large and spacious additional compartment increases overall comfort, but it significantly affects the price and weight of the tent (not to mention its overall dimensions). So when choosing for this parameter, it is worth considering the real conditions and features of the operation of the tent. We only note that in order to organize additional beds, it is worth paying attention to vestibules with a length of at least 150 cm — usually, they can accommodate additional places at least across, and often along the tent.

The number of bedroom entrances provided in tent design.

It is worth clarifying that if there are several bedrooms in the structure (see "Sleeping areas"), then in this case it is not the total number of entrances that is taken into account, but the number of entrances per bedroom. For example, if the tent has 2 sleeping areas, each with 1 input, then the characteristics will indicate 1 input to the bedroom.

In other words, if the design states 2 entrances to the bedroom, this means that each bedroom has two exits (regardless of the total number of bedrooms). Such a design is convenient primarily because you can leave the sleeping slot in the most convenient way, if necessary, without disturbing your sleeping neighbors. On the other hand, a design with one input provides a higher degree of thermal and moisture insulation; such tents are better suited for particularly unfavorable conditions.

Number of windowsprovided by the design of the tent. Windows provide the penetration of natural light and relieve you of the need to use additional sources of lighting during daylight hours; in addition, when properly positioned, they allow you to inspect the area without leaving the tent.

Both the rigidity of the frame and the reliability and durability of the tent itself depend on the thickness of the arcs. Usually, the larger and more capacious the tent, the thicker the arches are needed for the frame. Arcs made of plastic and fibreglass most often have a thickness of 7 to 13 mm, while steel and aluminium — from 5 to 16 mm. With an increase in the section of the arcs, the weight of the tent in the folded state also increases.

— PU (polyurethane). A polyurethane (PU) coating is applied to the inside of the outer tent. The protective layer of polyurethane increases the moisture resistance of the tent, at the same time, the strength of the awning fabric also increases. The main advantage of polyurethane is the ability to reliably protect seam joints. However, polyurethane protection is not the most effective, besides, the presence increases the weight of the tent. The use of polyurethane protection alone is more typical for entry-level (low-cost) class tents. In good quality tents, PU coating is complemented by other types of protection, often polyurethane is used together with silicone (Si).

— Si (silicone). The outer tent fabric is impregnated with silicone (Si). Silicone significantly increases the moisture resistance of the tent. The fabric impregnated with silicone acquires elasticity, its strength characteristics increase. This type of protection is considered the most technologically advanced and functional. The tent itself is impregnated with silicone (from the outside), and sometimes a PU coating is additionally made from the inside for better water resistance. The main disadvantage is the inability to protect seam joints. For this reason, the seams in silicone impregnated tents are glued separately.

An indicator that reflects the ability of the tent awning to withstand moisture without getting wet. It is expressed in millimetres of water column — the height of the water column that the awning can withstand (the area of impact is out of the question, because the load per unit area under water depends only on the height of the water column and is not related to the area of \u200b\u200bits base). The significant figures indicated in the characteristics (for example, 4000 mm of water column, i.e. 4 metres) are due to the fact that raindrops can have a significant speed and, when they hit the tent, create a load at the point of impact comparable to the pressure on depth of several metres.

In general, the higher the waterproof rating, the better the awning will cope with the effects of rain and snow. Indicators up to 3000 mm w.c. Art. are considered sufficient for places where it rains rarely, awnings for 3000 – 7000 mm of water. Art. allow you not to be afraid of intense downpours, and in expeditionary (see "Destination") tents designed for extreme conditions, this figure can reach 10,000 mm of water. Art. and even more. However, more water-resistant fabrics, usually, have a significant weight, so in each individual case it makes sense to choose the option that is optimal in terms of durability and weight.

The corners of the tent are one of the "critical" places: in the unfolded state, they have almost the greatest stress, and the fabric in this place can be torn. To avoid this, many tents are equipped with reinforced corners. In this case, strength can be increased due to multi-layer sewing, special fabric or additional firmware.
