Tent — a temporary dwelling from a fabric which is quickly erected collapsible structure, designed to protect against adverse weather conditions and temporary stay and residence of people, works, commercial needs, as well as storage of various materials, property and equipment in the field. Widely applied to temporary settlements by tourists, travellers, armed forces and representatives in mobile occupations — a soil scientists, archaeologists, geologists, shepherds, etc p. Some tents can also be used as clothing (see cloak-tent).

Types of tents for the use
Assault tents used in rugged mountain Hiking and long climbs. Average weight, firm, moderately voluminous, are going fast. If well done — will withstand any weather. Due to the detachable grids of different density is easily regulated microclimate. If the fabric is good — noticeably warmed by the breath of even one person.
Assault ultra-light tents are used for so-called "Alpine" style of climbing, with a little duration of the route. The main characteristics of assault tents is the weight and size. Very light, very strong, very small, are going fast. To live long in them seriously, as even to sit is problematic.
Expedition tents — similar to assault, but is designed for use in less extreme weather conditions. Usually there is no snow skirt, the fabric is simpler, usually a little more volume in the same class. A good option for forest stays in the middle lane.
Trekking tents — similar to forwarding, but even easier, as it is not designed for wind and severe weather. Taken for overnight stays on the equipped Parking lots along the trail.
Tents for base camp for "Himalayan" style of climbing when the climbing put the base camp. Tent for base camp is designed to ensure that a long stand in one place in any weather, so it should be wind-resistant design is tough enough to withstand the pressure of wind and snow. Its volume is large enough that it could accommodate a few people.
Camping tents — superior, which primarily affects its size (high, large) and weight (usually very heavy tents, which is impossible to bear for a long time, so they are used to traveling with vehicles). Disadvantage — due to the large volume and medium quality tissue bad breath warmed on cold nights can be quite cool. An obvious plus — high altitude. Make sense, if long (at least 3-4 days) to live in one place.
Beach tents — small tents for a short rest, mostly in hot weather without rain. Have just one camera, usually not very thick, therefore the air was not so hot during the day, as in the other tents. This is the most affordable and usually the most short-lived of the tent. Not designed for the rain, well absorb moisture.

Types of tents for construction
Tents consist of a frame and awning.
a frame tent is strengthened with wood, metal or plastic frame (frame tent):
Frameless (rack) of the tent are secured to the braces between the trees (in the forest zone) or one (type "a tent") or multiple racks.
Frame tents type "hemisphere" is a few intersecting arcs (from 2 up to 6), forming a hemisphere. Pros — great vetrostojkost, does not require stakes for installation (in the mountains preferably the fastening of storm delays). Cons — a lot of weight.
Arc tents are made of
Arc aluminum is quite durable and lightweight, but more expensive, so they are used mostly in assault and expedition tents, where the weight of the tent is of great importance. Arc made of fiberglass have the best combination of strength and cost. Steel arc commonly used in camping tents, which are designed for a large number of people and have a large frame.
Frame tents type "flip" is a somewhat parallel set of arcs (from 2 up to 5), arranged parallel to each other. Main advantages — one large height over the entire length. Negative — vetrostojkost smaller than that of the hemisphere.
Single-layer tent made entirely of waterproof material. The advantages of this design are its lightness and compactness in collapsed form. The main drawback — the drops of condensate formed in cooler weather, on the inner walls of the tent, drains directly on the floor, leading to a gradual dampness things. For this reason, single-layer tent got fairly narrow spread.
The vast majority of modern tents has a two-layer design.  Shelter in this case is really two tents: internal and external. Internal light, with walls of "breathable" fabric. External — waterproof. Between these two layers, leaving a gap of about 10 cm. The moisture released during breathing of the man, passes through the first layer and condense on the outer tent, flowing down as drops on the ground and not touching dry things inside the tent. Pros — dry things and the best thermal insulation. Minus a few more weight. The awning must not touch the inner tent (so as not to get wet in this place).
Through an open entrance is clearly visible to the vestibule of the tent
The vestibule is extra space under the outer tent. Serves as a place to store things and changing street shoes. In periods of extended bad weather in the vestibule can also prepare food on a gas burner (you must open the entrance and ventilation to not be poisoned by carbon monoxide).
Ventilation the holes in the roof or walls of the tent, providing fresh air and allowing partly to combat condensation. On some models, has access to these holes from the inside of the tent. Through the ventilation holes should not get precipitation.
"Skirt" — an additional strip of cloth around the perimeter of the tent, protects the inside of the tent from blowing wind. Can be sewn on or removable. Being under the top stones or snow skirt provides additional wind resistance and insulation of tents. The presence of the skirt should be in the mountains and at low temperatures. At the same time, in calm, windless weather can cause condensation. 
Types of tents according to seasons
Summer tents — oriented use, especially in warm or hot weather. Characterized by improved ventilation, due to the fact that the edge of the awning is raised high above the ground, and the walls of the inner tent is made primarily of a well-blown fabric or mosquito netting.
3 seasonally — designed for use in both warm and cool fall and spring weather. Able to withstand prolonged periods of rain. The inner tent is made of more dense fabric to make it warmer and reduce the blowing cold wind.
Winter (or 4 seasonal) — designed for use in freezing conditions and strong winds. Focused primarily for climbing and Hiking in the mountains, above the snow. The characteristic wind-resistant design with a large number of arcs, more dense and robust fabric awning. Not rare along the perimeter is equipped with a snow skirt.

Materials for making tents
Currently, for the manufacture of tents used by the following types of materials:
Polyester (designated: Poly (eng.)).
Nylon (Nylon (eng.)).
Tarpauling (Tarpauling (eng.)) — used to make bottom of some tents. Consists of twisted linen weave narrow strips of polyethylene, laminated on both sides melt.
Kinds of fabrics
The Ripstop Material (R/S).
Polyurethane (PU) is a traditional finish for increased water resistance of an awning or tent bottom.
Silicone (SI) — more than a new coverage. In addition to the waterproof function gives the fabric greater strength and resistance to ultraviolet light. Polyester fabric is significantly lighter PU, which affects the total weight of the tent. But at the same time, it is much more expensive.
The largest portable tent that can accommodate 34 thousand people, was used by the mission, Reinhard Bonnke from 1984-86, for evangelistic worship in Africa.
