In principle, any modern two-layer tourist tent has approximately the same components. Rather, it will be said, not “components”, but “parts of the structure”. Namely, external awning, frame, inner tent.
External tent of a two-layer tourist tent, water resistance, tent material, methods for attaching an external tent to the inner tent, elements for attaching to the frame.
And everywhere their tricks will be present. They must be known and taken into account in order to choose the right tent, which will serve you long and true. So, where does the tourist tent begin at first glance? This is an external awning. The material from which it is made is important here. The following requirements apply to the material:
It should not leak.
Must be durable and relatively light.
The space between it and the inner tent should be large enough.
At the very least, it should be enough so that the outer awning, which is soaked in the rain and therefore heavy, does not touch the inner tent. Otherwise, everything will get wet. In addition, this space serves to drain condensate, which is always present. If condensation does not form, then either you have a good tent or you do not breathe at night. You should also pay attention to the seams connecting the parts of the tent. They must be glued, otherwise you can forget about water resistance.
Watertightness of the outer tent of the two-layer tourist tent in millimeters of water.
It is also worth remembering such a quality criterion for an awning: the height of the column of water that it can withstand. This, of course, does not mean that the tent can be put up, say, at a depth of 10 meters, and it will not get wet. Simply, when drops of water fly from heaven, they hit the outer awning with great force. And the higher the water resistance of the tent in millimeters of water, the better.
But if you know in advance that your chosen tent will never leave the boundaries of ordinary forests and plains, then you should not buy a steep tent designed for climbers, highlands and other extreme vacations that can withstand pressure up to 7000 mm of water. This is undoubtedly a good quality camping tent, but not always required.
Do not forget that over time, the material wears out and gradually begins to leak. Accordingly, the greater the water resistance of the awning, the longer the tourist tent will last you. So if you are going to put up a tent in the conditions of torrential rains, then the waterproofness of the tent should be at least 3,000 mm. If the material from which the outer tent is made has water resistance characteristics below 1,500 mm, you can be sure that the tent will flow under heavy rain.
In addition, the quality of the fabric can be determined by the presence on its outer side of a special water-repellent coating. It reduces the wetting of the material. Thanks to such a coating, water droplets will slide off the fabric and not be absorbed. In this case, when wet, the tent fabric will stretch less.
If this coating has worn off over time or if it was not there initially, then special formulations can be used to restore or apply it. This will extend the life of your tent, saving yourself at the same time from the vagaries of nature, manifested in the form of rain.
Material of the external tent of a two-layer tourist tent.
The material of the outer tent of the two-layer camping tent also matters. Today, in the production of tent tents, manufacturers use fabrics based on polyamide fibers (Kapron, Nylon, Taffeta) and polyester fibers (Polyester, Poly Taffeta, Lavsan). It is better if the outer tent of your camping tent is made of polyester fabrics.
Polyester fabrics hardly stretch when wet. They are more durable. Of course, they cost more, but in this case, the price justifies the quality, extending at the same time the life of the tourist tent. Still getting acquainted with the description of the fabric, it is worth paying attention, for example, to such designations: 175t – 250t. This is the “tack” of the fabric. The larger this figure, the thicker and stronger the material, but its weight also increases.
If the purchased tourist tent will be used in extreme conditions, then it is worth choosing a more durable fabric. To increase the tensile strength while maintaining the same weight and slight stretching when wet, thicker threads can be woven into the fabric after a certain interval (4–5 mm). The fabric will look as if in a checkered box. This technology is called RipStop..
These denser threads can be located at different angles, for example, forming a rhombus at the intersection. Sometimes the color of a dense thread is different from the color of the main. Due to this, a very original fabric can be obtained.
Another characteristic of fabric quality is Den (Denier, Denier). This is a unit for measuring the thickness of a thread in a fabric. The larger this figure, the thicker the thread, respectively, the thicker the fabric. When designating the characteristics of fabrics, the thickness of both longitudinal and transverse threads may be indicated. Then this figure will be written as a fraction: for example, 70D / 75D.
Methods of attaching an external tent to the inner tent.
The methods for attaching the outer tent to the inner tent may vary. For example, this option: the frame can be located outside the awning and fastened to it through pockets, and the inner tent is simply suspended from the awning. In this case, the tent is very easy to assemble. In addition, you can safely put it in the rain, without fear that the inner tent will get wet.
Another variant. The frame is hung on hooks or inserted into the pocket of the inner tent, and the outer tent is pulled from above. In this case, the inner tent is first set up, and the outer tent is attached only later, so if it rains, then a tent of a similar design should be put up as soon as possible, otherwise it will get wet. But in hot and dry weather, the external awning, which becomes optional, can be removed altogether.
As for the fastening elements of both the external tent and the inner tent to the frame, there is a wide variety of options:
Hooks Quick and easy.
The ties. It will take longer to mess with them, but they are more durable.
Velcro. Fasten the inner tent or outer tent to the frame very quickly, but also fail quickly.
Pockets The most reliable option, but requiring great installation effort.
