Comparison SOL Anchor 4 vs Tramp Bell 4

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.

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.

— Reflective elements. The outer surface of the tent is equipped with special reflective inserts. Thanks to this, the location of the tent will be visible from afar, which allows users to quickly navigate in the dark, easily determining the location of the tent city / tent. Often, reflective fibers are woven into wind braces so that at night they do not catch on.

— Mosquito net. Fine-mesh mesh covering the openings in the tent: entrances, windows, ventilation openings. Its presence is highly recommended if you plan to use the tent in the warm season: it allows you to ventilate the interior without letting mosquitoes and other unpleasant flying insects inside.

— Lantern loop. A special mount (loop, hook or carabiner), usually under the ceiling, designed to secure the lantern inside the tent. It will allow you to easily organize indoor lighting and eliminate the need to hold a flashlight in your hands or independently find a place for its best location.

— Internal pockets. Pockets located on the inside of the tent. They facilitate the organization of the internal space, allowing you to conveniently place relatively small items — glasses, watches, some tools, etc. It also reduces the risk of accidentally crushing fragile items.

— Shelf for small items. The purpose of t...he hanging shelf is generally similar to the inside pockets (see above): to organize the space inside the tent so that small items are not lost and are not accidentally crushed. In some tents, there may be several such shelves. Shelves are usually located in the upper part of the tent, which allows them to also be used as a stand for a lantern if there are no loops for it (see above) or it is impossible to use it for some reason.
