Quick install system
The special design of the tent frame, which
facilitates its installation.
The specific design of quick install systems may vary. Often, a rigid folding frame is sewn directly into the awning, which eliminates the need to reattach the awning to the arcs every time. An inflatable frame (see "Frame type") or a base made of an elastic material can also be used. The disclosure system itself may also differ from model to model. For example, in many classic tents, an umbrella-type mechanism is used (there are even so-called umbrella tents — see “Purpose”; although the matter is not limited to them). In other models (mostly small products like winter fishing tents), the product is first “flattened” and then bent in a special way, turning into a small flat disk.
The advantage of quick set up systems is evident from the name — they greatly simplify the deployment and folding of the tent. As for the disadvantages, most often this is a high cost due to the complexity of the design, and somewhat reduced reliability (for the same reason). In addition, ease of unfolding does not always mean ease of folding — in some models this is a rather "cunning" procedure.
Bedroom entrances
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.
Frame type
— External. The external frame is considered more convenient to set up, especially in the case of double-layer tents (see "Inner tent"), since both the inner tent and the outer awning are put on the frame at once. On the other hand, such a frame is more susceptible to the negative influence of natural conditions and does not allow the inner tent to be set up separately.
— Internal. The internal frame is somewhat more difficult to install than the external one; at the same time, it is less susceptible to the influence of unfavorable external conditions, and in double-layer tents (see "Inner tent") with an internal frame, it is usually possible to install only the inner tent, without an awning.
It should be noted that only tents in the shape of a hemisphere or half-barrel have a classic frame (see "Body shape"); in the case of
gable tents, the characteristic "external/internal" refers primarily to the location of the supports, and the term "frame" is not applied at all to tent models.
—
Inflatable. In such tents, the role of the frame is played by sealed hollow tubes made of flexible material (rubber or polymers), usually arched. When folded, they can be rolled up quite compactly, and when the tent is set up, they are inflated (usually with a special pump), acquiring the desired shape and sufficient rigidity to support the awning. The advantages of inflatable frames are their
...light weight and ease of installation; they usually belong to quick-setup systems (see above for the latter). On the other hand, inflatable elements are very sensitive to damage: a small crack or hole, not critical for an element of a regular frame, disrupts the seal and makes the tent unusable.
— Pop-up. An automatic type of arc frame — it unfolds automatically when the tent is removed from the cover. This type of frame is often used in small budget tents, intended for those who prefer camping, nature trips and music festivals. Such tents are packed in a small round bag, which takes up a minimum of space in a car trunk or among the hand luggage of vacationers.Water resistance of tent
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.
