Jacket, also known as windbreaker or raincoat, is one of the necessary equipment for outdoor sports lovers. Whether you are an urban leisure group or an ordinary weekend outing enthusiast, whether you are doing long-distance hiking, professional exploration, ice climbing or even climbing seven or eight kilometers of snow-capped mountains, an "all-weather" jacket suitable for you is your essential choice.

Jackets are the first choice for all outdoor lovers because of their all-weather functions. The general jacket is mainly reflected in the waterproof characteristics. Generally speaking, jackets are jackets in terms of fabric design and processing.

It is "PU waterproof coating+glue pressing at joints". PU waterproof coating refers to the process of attaching this waterproof coating (PU polyurethane) to the fabric on the surface of clothes, and the thickness of the coating varies according to the needs. This waterproof coating is widely used in national defense, automobiles, buildings, furniture and even condoms. Even the lining of fire hose has PU polyurethane coating. Practice has proved that a good PU coating will not leak water. As for glue pressing, it is mainly to carry out special glue pressing treatment on the PU coating at the stitch and seam of clothes, which is easy to be damaged and seeped. Generally, professional glue press and adhesive tape are used to press glue at the joints at high temperature to seal all joints to further prevent water leakage and seepage. Its disadvantage is that clothes are airtight and windproof. Jacket, as its name implies, is the clothes worn when rushing to the top, and it is one of the necessary equipment for outdoor sports lovers. From the perspective of modern mountaineering, the jacket should meet several conditions: First, the structure meets the requirements of mountaineering. Mountaineering is often carried out in harsh environments, including weight-bearing walking and technical climbing. The jacket structure should meet the requirements of these activities. Secondly, the materials must meet the requirements of mountaineering. Due to the special environment and needs of mountaineering, the material of jacket must meet the requirements of windproof, waterproof and ventilation.

Now many outdoor goods stores are operating internationally renowned brand Pinrui, and its price is a fraction of that of regular shopping malls. Everything in these stores is basically from domestic processing plants, and it is all through an underground channel. This is also a factor that makes the price difference between the two several times. But this is good news for us outdoor lovers. In the past, some people divided this product into dumping and fake dumping, but since the year before last or last year, foreign manufacturers strengthened the management of surplus materials, real dumping has been rare. It can be said that there are no really dumped coats on the market (excluding big shopping malls like Saite), which are basically fake dumping, let alone genuine ones. What are the meanings of dumping and fake dumping? Dumped goods refer to those products left by manufacturers after processing for foreign companies. Generally, the quantity is not very large, and there is no essential difference in quality from Saite's products. Fake dumping refers to the processing of surplus fabrics and accessories by domestic factories. The question involved here is whether the factory uses the material of the clothes itself when processing these products. If so, then the difference between quality and dumped goods is only a matter of workmanship, and there will not be much difference. The so-called real coats on the market are basically like this. In order to pursue profits, some manufacturers will change some materials, such as embroidering non-GTX fabrics with GTX and so on. Therefore, when buying a coat, you must look for places with good reputation, such as Pinrui and Sanfu. Their supply of goods is good, and the merchants' own appraisal level is high, which is guaranteed to some extent.

Edit the clothing features in this paragraph.

The so-called professional waterproof means that whether you are sitting in a wet place or walking in a stormy environment, you can effectively block the invasion of rain, snow, frost and snow, so that water can not penetrate into clothes and make you feel wet and cold; The so-called ventilation means that when doing outdoor sports with a lot of exercise, the body naturally sweats and the skin exhales a lot of water. If you can't send it out of the body quickly, it will definitely lead to sweat trapped between your body and clothes, which will make you wet. On rainy days, it will make you feel wetter and colder. Especially in cold conditions such as mountains and canyons, it is very dangerous for the body to get cold and lose temperature, so good air permeability of clothing is very important. The so-called windproof means that 100% prevents the air cooling effect. In the changeable natural environment, when the cold wind penetrates our clothes, it will blow away a layer of warm air near our skin. This layer of warm air is about one centimeter thick, with a temperature of 34 -35 degrees and a humidity of 40%-60%. Even a slight change in this warm air will make us feel cold and uncomfortable. When cold air blows into clothes, it destroys this warm air, leading to rapid heat loss and body temperature drop, and we will immediately feel a little chilly. This is the so-called air cooling effect.

When people generally mention jackets, in the catalogues of major manufacturers, most of them are called parka, and there are not a few jackets. According to Webster's dictionary, the word parka comes from Russian, which means hooded leather pullovers in the Russian Arctic. Later, it was extended to all hooded and lined pullovers or jackets. Stylistically, modern parkas are generally made into short windbreaker style, and the hooded has accessories such as sliding buttons to adjust the shape and head shape of the hooded to kiss the coat.

Close; There is usually a thick or thin wool lining at the neckline to reduce the heat loss here; Thickened shoulders and elbows to enhance wear resistance; The opening of the inner bag is outside the zipper to reduce heat loss, and the opening of the pocket is higher or there is a chest pocket to avoid the situation that the backpack belt can't take things out; The back piece of clothes is slightly longer than the front piece, and the sleeves are slightly bent forward to compensate for the movement; There are usually underarm zippers (but there are exceptions, such as TNF's notorious core exhaust system), and some have snow skirts. The style of jacket is more life-oriented, and there is generally no hood. According to the different materials, Parker coats and jackets can be divided into three types: windproof/breathable, windproof/airtight, windproof/waterproof, and the windproof/breathable representative is of course the famous GTX. Windproof/airtight may sometimes be fancy, but it is actually a plastic raincoat. As for windproof/waterproof fabrics, even if they are soaked by light rain for a long time, they will leak water, which is not practical in outdoor activities and may be considered in urban tourism. Most raincoats sold in fashion shops are of this kind. In addition to the differences in materials, the latter two categories often simplify some things in design, such as underarm zipper, snowflake skirt, sleeve-shaped jacket and so on.

Shape, sliding button of range hood, etc. It looks more active and less strange. As for raincoats, they are not bicycle ponchos or disposable plastic ponchos that we remember. It is a general term for waterproof clothes that are lighter than parkas-sometimes classified as ultra-light raincoats. In order to reduce the weight of this kind of clothes, the lining is usually cancelled, the waterproof and breathable materials are directly attached to the inner surface of the fabric, and the thickening and other small things on the leather coat are also cancelled. Of course not in velvet. A raincoat sacrifices a certain strength and gains a lighter weight-it can be lighter than a fur coat with a smaller compression volume of the same size1/3-which is less than half of that of a fur coat after compression. Most of the styles of coats are similar, the key is to see what you like and what suits you. There are mainly long models and short models, as well as color matching and monochrome. Generally speaking, the long style is better than the short style, and the color scheme is better than the monochrome style (mainly good-looking). At the same time, we should pay attention to whether it is the European version or exported to Japan, whether it is male or female. Jacket is a kind of functional clothing, and both men and women are very particular about it. Generally speaking, women have smaller sleeves and slender waist. Another most obvious difference is that the main zipper on the chest of men's models is inserted from left to right, while that of women's models is the opposite. A professional sharp jacket should have the following requirements in design: wear-resistant layers on shoulders and elbows; There should be windbreak skirts or windbreak feet in the middle and lower parts to prevent wind from pouring into clothes from the hem; There should be a breathable zipper under the armpit, which can be directly opened for ventilation when sweating a lot; Built-in hat can be put away when not in use. There are also some details, such as a small hook on the cuff, which can be used to hang gloves directly, and so on.

Edit this piece of clothing material

PIZEX is talked about everywhere Whether PIZEX is good or not has been proved by many parties. Anyway, it is the best outdoor material. However, some people in China are superstitious about PIZEX. In fact, many other jacket materials are equivalent to or even better than PIZEX in performance. In addition to PIZEX, there are Conduit, Omnitech, Memo-tex, Power-tex, Hydro-dry, Weatherite and so on. The general characteristics of these fabrics are waterproof and breathable, not to mention the performance data, and there is not much difference in performance in use. Many people are asking how to identify PIZEX. I have my own secret skills here, which was told to me by a friend of mine. Real PIZEX series products, hard objects (such as nail tips) on the coating will leave black marks on it, as if it had been cut off. This phenomenon is generally PIZEX, and it also applies to pizex-dryloft. But at the price, you have to damage your matching clothes. Ha ha! The fabric we are talking about is PIZEX, which mainly refers to the film inside the outer nylon fabric, and some people call it coating, not the whole fabric. As for the outermost nylon cloth, there are plaid and non-plaid. Generally, the plaid has better tear resistance because it uses stronger fiber yarns. Tear-proof is a good outer layer material. Another key of the coat is the adhesive tape, which is the adhesive tape pressed on it at the joint to prevent water leakage. The real goods have passed strict waterproof test when they leave the factory, and the tape generally does not leak. But as I said before, the jackets we are wearing now are generally fake, and there is no strict inspection procedure, so there is water leakage, but generally not much. This is a technical problem. A good rubber strip is breathable, and an airtight rubber strip has little effect on the overall permeability. The lining of the jacket is also made of breathable material, generally coolmax, which is mainly to enhance sweat conductivity and warmth retention. The light jacket is made of mesh fibers and won't stick to the body. There are also those without lining, that is, the so-called three-layer glue and two-layer semi-pressed glue. The three-layer adhesive directly presses a layer of breathable material on the inner side of the waterproof breathable film to protect the breathable film from being worn. Two-layer semi-laminated adhesive mainly refers to gore-Tex PAC of Gore Company. Its principle is similar to that of three-layer composite glue, and it looks like a point from the inside. This kind of clothes is characterized by light weight and better air permeability, but it is more expensive. There are also some accessories, including zippers, bayonets, shackles and so on. The zipper of a jacket is usually YKK zipper. There must be something wrong with the fake YKK zipper jacket, so don't buy it. YKK zippers can be bought in China now, so the accessories are not very important.

Edit the price of clothes in this paragraph.

Of course, waterproof/breathable snow coats are the most expensive, generally ranging from 0 to 500, while waterproof/wind-resistant ones are much cheaper, ranging from tens to zero. Waterproof/breathable raincoats are also at this price. Waterproof/airtight is the cheapest-no matter how luxurious a plastic raincoat is, it's just a plastic raincoat-it can be done for a few dollars to dozens of dollars (but the strength of this thing is doubtful: I saw with my own eyes how someone bought a new plastic raincoat step by step from clothes to sacks in two days in a weekend). Because most outdoor goods stores in China do not clearly distinguish these kinds of clothes, they are just collectively referred to as coats, which requires you to pay attention to yourself when buying, ask more questions and see more.

Edit the production brand in this paragraph.

As can be seen from the structural characteristics of parka mentioned above, this kind of clothes mainly keep warm in cold environment, so you can never expect it to have high performance in not too cold environment-even GTX-XCR clothes will be worn in spring, summer and autumn in the climate in the suburbs of Beijing, and then you will jump up and down for half an hour with a big bag weighing dozens of pounds, and sweat will accumulate inside the clothes. Because I mainly go out in spring, summer and autumn, I pay more attention to weight and permeability, so I prefer raincoats. ; Of course, waterproof/breathable snow coat will be more suitable for those travelers who are more active and pay more attention to the strength and reliability of clothes. If you just travel in the city, you can definitely find shelter from the rain within an hour. A cheap waterproof/windproof coat is enough, and there is no need to spend more money to pursue those functions that will never be used. In the final analysis, it's the same old question: what do I need? If you know your own needs, you will spend less. As for the brand of jacket, compared with the situation that TNF dominated the country in the past, there are more brands that can be seen in China now, and new brands are constantly appearing, which can also explain the development of outdoor sports in China from a certain aspect. TNF first entered the China market and is the most common brand at present. Generally speaking, its coat is good, especially several classic styles, which are enduring for a long time. Unfortunately, there are too many fakes. Anyone walking in the street is fake TNF, which is inevitably disgusting. MHW is the most popular clothing brand now, which is very good in details and more attractive in style. In addition, there are some brands, such as Mormot, Black Yak, Saloua, Colombian, Big Packaging, Lao Alpes, Montebell, King Tex ak Club, and Orsoka. Personally, I feel that MHW and TNF products are still relatively good, and other brands have never experienced them. Well-known foreign brands include Columbia, Archaeopteryx, Lespheus and so on. The price of these brand coats is at least above 1000 yuan. If it is lower than 1000 yuan, it is definitely not genuine, such as foreign trade original orders, tail orders, high imitation and so on. Well-known domestic brands include Mustar, Snow Wolf and Polaris. These brands are characterized by the use of domestic DENTIK fabrics or self-developed fabrics. Although there is a gap with GORE-TEX in performance, they are more than enough for ordinary outdoor mountaineering activities.

Edit the production process of this paragraph.

The manufacturing technology of jacket mainly includes: laser shearing, three-dimensional shearing, glue pressing, waterproof zipper, waterproof coating and windproof parts. Laser shearing can make the cutting surface smooth, tidy and hairless. Three-dimensional cutting can make the elbows, knees and other parts of clothes and trousers more conform to the human body curve and be more comfortable to wear. Glue pressing treatment at the joint can prevent water seepage. Stereo shear

Glue pressing treatment

The waterproof zipper is covered with a layer of waterproof glue to prevent moisture from penetrating. Waterproof coating, such as DuPont Teflon, covers the surface of clothes and trousers to enhance the waterproof effect and reduce the corrosion of materials by rain. Seamless zipper

Distinction between true and false

The "genuine products" only refer to the products sold through the channels approved by the manufacturer, such as stores, agents or retailers, and can enjoy the after-sales service provided by the manufacturer. Products purchased through other informal channels are generally referred to as "fakes" in this paper. The quality and service of international professional brands are guaranteed, but the price is too high for most people. The only way to buy such products is the specialty stores of various brands. If you plan to invest more than 30 thousand yuan in outdoor equipment, or those who are going to climb the snow-capped mountains (except big girls) are suitable to buy such products. Non-professional, non-international brand, high quality and high price. The high-end products of this kind of brand have guaranteed production lines and raw materials; However, due to the huge promotion and sales costs, the price is very high, so it is called high quality and good price. Non-professional means that the special design of such products for outdoor environment is not as good as that of real international professional brands. Non-international brands mean that such brands have not been accepted by the most developed outdoor sports market in Europe and America, and can only be barely maintained in the domestic outdoor sports market, which is still in its infancy. In addition, the low-end products of such brands are basically low-quality and high-priced, and there is no choice value. Growing domestic professional brands. Generally, it is a brand established by outdoor enthusiasts, which considers the needs of the domestic outdoor market in positioning and constantly improves products according to user feedback. However, due to the constraints of cost control, design experience and other factors, it is not as good as the above two types of products in terms of production technology, materials and comprehensive performance.

Fabric selection

The fabric of jacket is generally divided into the outermost protective layer, the middle waterproof and breathable layer and the inner lining. The protective layer and waterproof and breathable layer are pressed together, and the inner lining is separated from them, usually nylon wire, mesh cloth or some sweat-absorbing materials, mostly black. The adhesive tape at the joint is blocked by the lining and cannot be seen (unless it is separated by a grid cloth). Three-layer fabric: protective layer, waterproof and breathable layer and lining are pressed together to look like a layer fabric. Generally, the color of lining is mostly silver gray. You can see the layering at the seams of the lining. Generally speaking, the permeability and warmth retention of the two-layer fabric are slightly better than that of the three-layer fabric, but the three-layer fabric is light in weight, comfortable to wear (the two-layer fabric is a little timid) and small in folding volume (the coat is put in the bag most of the time in spring, summer and autumn). So unless you only consider using it in winter or snow-capped mountains, it is generally better to choose three-layer fabric. Two-layer material and three-layer material

Style selection

These are different types of coats, which can be understood as mountaineering, outdoor and rainproof mountaineering: the style is relatively simple, taking into account some special requirements when climbing. For example, the one-piece hat-windproof is better; There are no pockets below the waist-it's convenient to wear a seat belt. On the premise of ensuring strength, try to reduce the weight. -If you have a fever while playing outdoors, it is recommended to choose this one. Outdoor style: suitable for many types of activities, with complex styles and diverse functions (basically more pockets), which is heavier than mountaineering style. Rain protection: the simplest style, the lightest weight, the thinnest fabric, the cheapest price and the worst air permeability! -If you don't have a fever when playing outdoors and don't want to invest too much, this is recommended. It is best to put it in a backpack when traveling (airtight) and put it on when it rains (stuffy is better than soaking wet).

Waterproof and breathable options

If common materials are waterproof, they are often airtight, such as plastic and rubber. Materials with good air permeability, such as cotton products, cannot be waterproof. The material used to make the coat has both waterproof and breathable properties, but the price of this consideration is that both waterproof and breathable properties are limited, so don't expect too much. Generally, when climbing a mountain continuously, I feel bored. In the continuous heavy rain, it is always wet inside. Waterproof: the fabric of the jacket is waterproof as far as possible on the basis of ensuring a certain air permeability, but its waterproof performance is far less than that of plastics, rubber and other materials. Breathability: steam method: pour hot water into the cup, cover the cup with the fabric of the coat, or press a piece of glass on the fabric. If you see hot air coming out through the fabric, or water vapor condensing on the glass, it means that the fabric is breathable. However, it should be noted that the permeability of different materials is different, and there is a high bottom. The above tests can only qualitatively prove that the material is not completely airtight, but the air permeability is still unknown.

Edit the detailed explanation of this garment fabric.

Gortex

The so-called waterproof and breathable fabric is actually a kind of synthetic polymer composite membrane, whose molecular gap is larger than air and smaller than water molecules, so it can shelter from rain and sweat at the same time. Gore-Tex, this is Gore's flagship product. Its scientific name is polytetrafluoroethylene (PTFE), and Gore-Tex is a porous film that needs to be laminated in a layer of nylon material before it can be used as a clothing fabric. Because its pores are smaller than water molecules and larger than gas, it is theoretically waterproof and breathable. Through the mesh lining of the suit, you will see the white colloidal film pressed on the nylon material. Three-layer gore-tex is a kind of double-layer material with a layer of breathable material added inside. Because the three layers of materials are tightly stuck together, the Gore-Tex film inside can't be seen. Its advantage is that the inner layer can better ensure the Gore-Tex film is not worn, but its disadvantage is that it is heavier than the two-layer Gore-Tex and its air permeability is slightly lower. Because most Gore-Tex is laminated on nylon, you feel like a layer. Gore-Tex products are waterproof, but the air permeability is not as good as other waterproof materials. Generally speaking, Gore-Tex has a good comprehensive effect and is the most commonly used waterproof vent product at present. Of course, Gore-Tex's speculation in recent years is too vague. I hope everyone will not be superstitious. Gore-Tex PacLite This is Gore's latest waterproof and breathable material. It is at least 15% lighter than ordinary Gore-Tex, and the compressed packaging volume is also very small. Actually, the jacket made by PacLite is very light. TNF's Ama Dablam jacket made of PacLite is only half as heavy as the traditional mountain jacket. Gore Company authorized only a few manufacturers to produce in the autumn of 1999. For example, woodchucks, mountain hardware, and the northern face of the United States. Mammut, Berghaus, Schoffel, the highest performance of manufacturers outside the United States. OMNI university of technology

Omni-Dry Columbia Company has developed its own moisture-absorbing and quick-drying material, which can not only absorb water quickly, but also effectively volatilize the moisture outside the fabric. Its water absorption is three times that of ordinary cotton cloth, and its volatilization speed is twice that of ordinary cotton cloth, so it can keep the wearer dry and comfortable, and is suitable for various outdoor activities. This material is mainly used to make T-shirts, shirts, casual pants and so on. Omni-Stop Omni-Stop Fleece is another special product of Columbia Company. It is made of waterproof, windproof and breathable Omni-Tech and warm MTR wool, thus becoming windproof, warm and breathable clothing, which is very suitable for cold environment. Omni-Tech Omni-Tech is a patent of Columbia company, which has the same waterproof, windproof and breathable functions as Gore-Tex material. The surface of the fabric is coated with DWR (durable water repellent) waterproof coating, so that rainwater cannot penetrate. The breathable film is pressed on the bottom of the fabric to help discharge body sweat, and the glue pressing treatment at the wiring makes it have professional functions in harsh environments. Even after 20 washes, it can still maintain 80% waterproof effect. Dentik

DENTIK fabrics developed by DENTIK China Dengtian Company also have excellent properties and are often used in domestic brands such as Mustag. This fabric has obtained the national patent of waterproof and moisture permeable fabric, and has been designated as the designated product by Alpine Armed Police Force of China People's Liberation Army. The waterproof and breathable index is above 20000. CoolMax, this is a kind of polyester fiber produced by DuPont company in the United States. It has strong perspiration performance, and can quickly excrete sweat from the inner layer to keep the body dry. CoolMax dries quickly and is comfortable to wear. It is an ideal material for underwear and socks lining. Some jackets also use CoolMax as a mesh lining. Cordura, this is a kind of high-strength nylon produced by DuPont company in the United States. Taking the denier of XX as the strength standard, the higher it is, the stronger it will be. For example, 160 D is the thinnest and 330 D is stronger. 500 D has high toughness, and many good backpacks choose it as the fabric, while 1000 D Cordura is only used for the best backpacks. Not only backpacks are made of Cordura, but also many coats and pullovers are reinforced with Cordura in places where shoulders and elbows are easy to wear. ConduitThis is a waterproof, windproof and breathable material developed by Shan Hardware Company, which is mainly used in various outdoor clothes of our company, such as Ascent, Tundra Jacket, ExposureII and so on. This kind of material is called active desiccant, which is the bane of wind, rain and snow in nature. DryLoft is an extremely light waterproof material introduced by Gore, which is mainly used to make sleeping bag jackets. The sleeping bag made of it and down is light, warm and waterproof. In recent years, this material has also been made into down jackets, which are especially popular among mountain climbers. Air outlet Air outlet can be called human body temperature regulator. It can absorb, store and release the body's heat, so that our body can keep normal temperature in extreme weather. It is often used as the material of underwear and socks (Lorpen chooses this material). Polartec, this is the material imported from muldoon Mills Company in the United States. It is by far the most popular pile product in the outdoor market. Polartec is lighter, softer and warmer than ordinary fleece shirts, and it won't fall off. It not only dries faster, but also has good expansibility. Polartec is divided into lightweight, middleweight and heavyweight. 100 series is light and suitable for making fleece pants. The 200 series is the most common, its warmth retention is better than that of 100 series, and it is not as heavy as the 300 series, so it is a generalist. The 300 series is warmer, so there is no need to go to a very cold place. There are also 200 bipolar and 300 bipolar series. This is a double fleece coat, which is thicker. Bipolar is warmer and suitable for wearing in cold areas. It is worth noting that ordinary people had better buy 200 series. You can wear a down vest if it is cold. More than 300 clothes are heavy to wear, and some are still wrapped in waste. It's too hot to wear and too cold to take off, which is not suitable for everyday wear. SympaTex SympaTex is a patent of VAUDE company, which has the same waterproof, windproof and breathable functions as Gore-Tex material. Often used in jackets and pants designed and manufactured by the company itself. TexApore is a waterproof, windproof and breathable material developed by Jack Wolf Skin. Thermastat, which is a material of DuPont. Sweating and keeping warm is an ideal material for underwear. Windbloc, this is a windproof material introduced by muldoon Mills. Wind barrier is a kind of film. Wool made of windproof cloth is very warm and windproof. It can prevent some water, but its air permeability is average. It can be used as a coat, or as a fleece for a warm layer (but it has poor air permeability). WindStopper This is a windproof material introduced by Gore, and it is also a kind of film pasting. There is no waterproof function, but it is windproof and breathable, and it is warmer than ordinary velvet products. It can be used as a coat or a stacked garment with a warm layer.

Edit this passage, clothing categories

According to the scope and environment of use, we divide Pinrui jackets used in outdoor sports into three categories: ultra-light and light functional jackets: these jackets are very light in weight and can be rolled into a ball to carry, and the materials used in these jackets are almost entirely suitable for fast marching, orienteering or hiking with low load and simple terrain. However, due to its very light weight, it has to make some compromises in scratch resistance and tear resistance. Moderate functional coating: more durable, but heavier than light functional coating. The middleweight functional coat is mainly used for moderate-intensity hiking, cycling or low-altitude mountaineering. Obviously, the range of application of middleweight functional outerwear is wider than that of light functional outerwear, but in order to reduce the weight of clothes on the basis of enhancing their functionality as much as possible, major manufacturers still make great efforts in manufacturing materials and processes. From the jacket products we recommend in this issue, you can also find that some well-known manufacturers have made efforts in this regard, such as using waterproof zippers; Use better materials to replace the wear-resistant layers used in traditional jackets on shoulders and elbows, and so on. Adventure-specific functional coat: The design concept of this coat is relatively simple, and it is usually the explorer's most loyal friend. With such a dress, you can cope with all kinds of complicated and bad weather conditions that ordinary people can't imagine. When the situation around you is getting worse, you will find how lucky you are to have such a dress. For example, when marching on foot in complex terrain, it is likely to be hit by heavy rain and there is nowhere to hide. You know, being in heavy rain for a long time is exactly the same as being in the snow, and the temperature around you is only a few degrees apart. At this time, a special functional coat will protect your body like a shell, so that you can avoid being soaked in rain and the rapid drop of body surface temperature. However, functional outerwear dedicated to exploration is generally very waterproof, so it is inevitable to make some compromises in terms of breathability.
