In 1985, Zhongdian Bitahai. tent? I didn't know what the tent looked like. It was probably a hidden bag or a class tent in the army. I was definitely unable to carry it back. So I took a large piece of plastic sheeting and folded it into a shape of "whole" at night. To block the rain, one side is covered with moisture. After two nights of distorting, the feeling of excitement is unforgettable.
The second tent is a girlfriend's sewing, a triangle, a plastic bottom, two hanging on the tree, too warm. This shows, on the other hand, how important secondary equipment is, and content is the most important.
Now many people cannot have such a feeling. You must think that the North Face is what you want. Then, let me talk about a bit of experience in shopping.
The more popular in the 1980s was the "inflatable" type. The skeleton of the tent was a pipe with a diameter of 10cm. After inflation, it was OK. In one investigation, lost in the swamp, the tent was placed in the mud, and the rain and water resistance were incomparable. Last year actually saw a British expedition still in use.
In the 1990s, the most common thing to see was the scaffolding of metallic materials. There are triangles, yurts, sheds and snails in a few shapes.
In general, the triangle is the oldest style, but it is generally heavier. The yurt is the most common.
When picking yurts, it is best to support the tents and observe whether there are any special forces in all parts of the tent. This is mainly whether the shed layout department is too tense or stressed. A good tent should be evenly supported by all parts. The seams should be glued. You gently fold the seams and you can see the glue on the seams. This is very important, otherwise rain will seep through the needle eye.
In terms of rain protection, the two floors are more reliable than the single floors. Mainly pay attention to workmanship, you want to carefully select pins and seams like a woman. Then imagine if a drop of rainwater will flow from the top to the bottom, if it will accumulate somewhere. If this is the case, even the best fabrics may seep. For tents, the first element is to prevent rain. (Of course, for alpine tents, it is wind-resistant, and the rain-proof is a little bit worse.)
For the tent bottom, generally more similar to the "woven bag" bottom, "PU" paint, more common in low-end products. This moisture resistance is still very good, but after repeated folding, some parts will be damaged, but also heavier, pay attention to preservation. The other is similar to the "Oxford Bottom." It will not be damaged after repeated folding, but many can not afford to "seep", that is, sleeping in a more humid place. At the end of the tide, special attention should be paid. Perhaps many of my opinions do not agree. The external account is the main force of the rain, the higher the density, the good is the coating, but expensive. Or Gore-Tex and other **-Tex materials are even more expensive. If the foreign account is able to reach the ground, with a little skirt, it would be better to rely on the air inside and outside the account to form a heat insulation layer, which also has a certain warming effect. It seems that there is a kind of fabric that is "anti-ultraviolet" and it is really ridiculous! Not to mention whether it really has that function. Isn't it UV that we want to come out for?
In terms of wind resistance, the more bars there are and the lower the tents, the better the effect. This is why the “alpine tents†are always smaller and lower, generally about 100-120 cm.
Vendors usually divide tents into three quarters and four seasons. I don't think it's an indicator of performance. It doesn't necessarily fully explain its use.
Because, the top tents are professionally distinguished.
The top alpine tents are often single-layered and have good air permeability so that the gas exhaled by the body does not condense on the inner wall. Moreover, the rain resistance is not the best. It considers that there are more snow in the environment and less rain.
The top of the wetland tents, bottom of the shed is like "inflatable boat material", I do not know the specific material. There was once one, Missi came during a joint inspection tour with Japan, and later gave a famous Chinese explorer on Dulong River, who devoted himself to Luo Bupo.
My suggestion is that if you are a junior player, buy a 300-500 double-deck tent, which can be 200*200 in size, and more people can participate with you. If you want to be able to go out often, buy a 150*220 pair of two people. It's lighter and you can get on your girlfriend, enough. If I want to "get in one step," I don't think I can do it, no matter what the purpose or quality is. The alpine tent that I use now is about 12,000RMB, which was sponsored by a Swiss mountaineering activity. It is difficult to obtain personal income.
It is important to go into nature and exercise our physique and spirit. This is the soul of the field sports. I oppose the pursuit of the brand and bring the concept of the city into this movement. Even if I mentioned the brand of The North Face, it is just an outdoor sporting goods brand. From the point of view, it is not professional enough. For an outdoor camping, 1000 specialties should meet the needs, and 2,000 yuan should be considered senior. If you have more budget, you can buy a 50-60 meter climbing rope, perhaps to use it when it is dangerous.
I never think that shopping can make you happy in outdoor sports. Always remember that you now spend a lot of money buying things you can't use, and five years later they have become a pile of bad things. Big deal, you buy one. A madman said to me that the best polar gloves are worn to be able to pick up a button. Do you need it?
Say a little more --- Alpine Tent
The previous article did not mention the specific brand. A friend talked about the experience of specific products. I also added it based on my understanding.
Ve25: Account 264×213×124CM, account 213×213CM, weighing approximately 4.7kg. Standard configuration for the United States "EASTON'7075 aluminum alloy, diameter 8.5MM struts, a total of 5. But sometimes operators will be equipped with glass fiber rods, strut strength greatly reduced.
Mount24 (also known as Mount Tent) is the typical product of The North Face in the high mountain account, weighs about 1kg than VE25. More domestic mountaineers use it. The main reason is that the price is affordable, can be bought, and can also be used. There are three factors.
Its structure is a geodesic dome structure, and then it is accurately called "multifaceted dome". To put it plainly, it is yurt-shaped. The newer product of The North Face is “Northwindâ€, which is the new version of The North Face classic product “Westwindâ€. It is a channel structure and can't stand up. In order to make way for the dome structure, Westwind stopped production for a while. Now it launched Northwind and re-routed the structure of the channel. My opinion is: There are differences between the two structures, but it is not essential unless higher-strength materials are used.
It should be noted that the wind resistance of the tent is directly related to the quality of the fixed rope pull; it is related to the overall strength of the tent; and it is related to the wind direction corresponding to the tent.
What needs to be bought is the correct "shopping view". More than 100 pieces have not been used now, and they do not dare to talk nonsense. Introductory, I also said a little experience, meaning that I don't necessarily need expensive equipment, or I need to “purchase my own equipment as neededâ€.
Speaking of high mountains, I do not recommend that entry-level practitioners enter the mountains with high altitudes, complex terrain, and even topple without much experience, even if you have a strong body! Mountain climbing is a sport that requires a very comprehensive technology. It is not only a matter of equipment, but courage is not enough. Outdoor sports (because it is the entry) is to let us go into nature, enter the arms of the mountains, feel the natural changes in people, resolve life and misery, and gain the power of life. What I hope to enter is this "gate." Do not talk about "conquest," and don't use mountaineering as a competitive sport.
Talk about conquest? There is no doubt that human ugly nature is exposed.
Tent-3
Just like GORE's introduction to GORE-TEX, it is waterproof, windproof and breathable. No mention was made of fire protection, and BIBLER stated that its material "ToddTex" for breathable tents was "only" passed the flame retardant standards of the United States and Canada.
According to bible's introduction, “ToddTex†is made of three layers of nylon, and the outer layer is made of polyester film. The middle layer is “Extended PTFEâ€. “Polytetrafluoroethylene, also known as PTFE, is Among all synthetic polymer materials, the hydrophobic materials with the best resistance to high temperature and low temperature, strong acid-alkali resistance and solvent resistance can be used in many harsh environments. Therefore, it is also known as the "king of plastics." Polytetrafluoroethylene (PTFE) microfiltration membranes are produced by re-stretching membranes produced by non-solvent processes. They are invisible to the naked eye and exist in practically uniform pore sizes ranging from 0.1 to 10 μm. It can be used as a filtration membrane in medical sterilization, filtration, chemical antisepsis, air filtration and liquid filtration devices, which can filter out organisms as small as 0.01 micron, thus ensuring the removal of harmful substances such as bacteria and viruses. In fact, ToddTex is very suitable for tent fabrics, and also sees the quality of bibler from one aspect. Gore uses a type called “CROSSTECH†for fire protection and water separation. However, the statement regarding the prohibition of using GTX as a tent has not been seen. I used GORE-TEX tents made by Phoenix on the UK IRC, provided by Phoenix. At the same time, when Goretex is so hot, it is rarely used. There may be some truth to this, as Garuda uses "ByroTex."
Moreover, Sweden's HilleBerg believes that it does not necessarily need to use **tex materials. The double-decker accounts with good ventilation and can meet the requirements. The internal accounts are not dew. However, it is worth noting that each manufacturer promotes products from the technologies and patents they own to seek a bigger market.
When I wrote a few articles, I wanted to explain one thing. I chose tents to determine my own use, and I was able to do what I could. Bibler Americans were yelling expensively, and generally considered it to be its only drawback. In fact, I very much hope that there will be discussions on domestic products, or that I can give the purchasers a little reference.
Tempest23 is a weird product because it is not in the TNF catalogue, and I have never seen reviews of Tempest23 in North America, including in some rich review magazines and websites. However, it can be seen at home.
Tents (4) - Materials
Several posters were posted on the tents. They wanted to evaluate several models based on their own experience. However, if they think about it, they would inevitably have a few words or even be misled, and some would be difficult to buy in the country. The choice is too small. So let's talk about fabrics, but I'm not working on textiles. It's hard to avoid mistakes.
The domestic tents are not doing well. The main difference is that the quality control and material selection are quite different, and the detailed processing is rough. Naturally, the picky environment and discriminating users will not see it, but if you are not "critical" Can be used.
For shed cloth, the "base material" is basically nylon and cotton cloth, and there is no external waterproof coating or not.
We are concerned with the density of the fabric and it seems that it can be stronger and more rain-proof. This is also the case in general. There can be such an introduction, which is already the details we can understand.
"190T Nylon PU Waterproof Coating Joint Adhesive Inner Liner: Non-Tearable Nylon, Bottom 217T Nylon PU Waterproof Coating Seam Adhesive"
So now let's analyze it. What does it say?
190T refers to the density of nylon cloth, which is a general system (Tex) for marking the density of textile materials. What exactly is the density? A qualified down jacket should be 230T-250T, preferably 250T. After fluttering, fluff flies out and the density must be below 230T. The general umbrella is 150T. Such an explanation believes that you should have a basic concept. For better waterproofing, use anti-paint material or simply composite material (** TEX).
Nylon, probably we are too clear, this is it?
Polyamide fiber is also called nylon (Nylon), which is mainly nylon 66 and nylon 6, and is designated nylon in China, namely nylon 66 and nylon 6. Nylon fiber was developed and put into industrial production earlier. Because of its good abrasion resistance and resilience, it was the world's first synthetic fiber in the 1970s. However, because polyester fibers wear better than nylon, they gradually replace nylon. Nowadays, nylon accounts for only 20% of synthetic fibers worldwide. And usually see some very soft material is polyester fiber, as well as in the tent. And the nylon material is divided into filament and staple, the difference in manufacturing methods. Even need to "modified", such as nano-nylon (NC-Nylon) affects the quality of the shelving.
Seeing here, maybe it's already confused. Perhaps what the manufacturer wants is that you don't understand.
Let's take a look at "PU waterproof coating". PU (Polyurethane), which can be a big class, use it well, too much, defense, cars, construction, wood floors, furniture, even condoms. Good PU coating is not It will seep water, right! Fire hose lining is PU. Polyurethane (PU) according to its raw materials can be divided into aliphatic and aromatic polyurethane, aromatic urethane in sunlight UV yellowing decomposition, can only be used as interior paint, The aliphatic polyurethane coatings are UV resistant and hydrolysis resistant, and can be used both indoors and outdoors, but the aliphatic polyurethane raw materials are relatively expensive. Polyurethane can be divided into its coating types, and can be divided into water-dispersible and solvent-based polyurethanes. Water-based polyurethanes are non-toxic and safe. The protection of the environment has become one of the standard coatings of advanced countries in the world. However, there are few domestic productions, and most of them are low-grade. Products, products are almost all solvent-based (oily) and low-grade highly toxic TDI series of aromatic polyurethane coatings (indoor type). UV resistance is the meaning of it in it. It seems that this article is also easy for home improvement.
Finally, there is "pressing glue." This thing has a lot to do with machinery. GORE-TEX products have stringent requirements for glue. One domestic company is in Shenzhen and the other is in Nanjing. Finally, it is finally finished. Why? Write is so complicated? Just give beginners the choice of the tent. The last suggestion: the actual user word of mouth.
