Teach you how to choose a coat.

Lead: Jacket 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 adventure, ice climbing or even climbing seven or eight kilometers of snow-capped mountains, what is right for you? All weather? Jacket clothes are your essential choice. The word "jacket" was translated from abroad. Outdoor jacket? Why not call it? Outdoor coat? And then what? This is a stranger to outdoor sports before, this kind? Outdoor coat? It has become a kind of professional clothing, in order to distinguish it from ordinary jackets. Jacket? .

As can be seen from the translation, jackets are used as professional equipment in China, so they are not so popular. In fact, in foreign countries, jackets have long been a necessary ordinary dress for people, and they are not necessarily used for mountaineering and rock climbing. The biggest function of the coat is to prevent rain and wind, but also to prevent cold and keep warm, which doomed it to be completely useless in daily life. Now, jackets are becoming popular in China. Men and women wearing jackets can often be seen on the street, and now there are many styles, which are casual and comfortable. On the premise of ensuring the function, people's daily aesthetics and use should be taken into account as much as possible. Now that the jacket has become popular and entered the homes of ordinary people, which brand of jacket is good? How to choose so many brands?

If you are an outdoor sports enthusiast, you are keen on outdoor adventure and other exciting activities. For safety and applicability, it is recommended that you have a set of top brand equipment. After all, there are not many such professional sports every year, and having such a set of equipment also makes you more professional and dedicated. In the eyes of travelers, you can be called a real enthusiast. There are many top brands in the world. Of course, the most famous is the Archaeopteryx jacket in Canada. Of course, these brands are also very expensive.

As an ordinary consumer, there are only one or two outdoor activities a year, mostly leisure sports, traveling, or wearing functional clothes at work, so there is no need to pursue these? Major? And then what? Top？ Nowadays, there are many coat brands, and many domestic brands can also meet the general functional requirements, and it is also good for rain, wind and warmth, and the price is much cheaper. We recommend that you use these brands. These brands, such as Columbia, TheNorthFace and JackWolfskin in the United States, are also relatively expensive, and they are popular all over the world, both casual and professional. However, there are too many brands sold online in China, especially fakes, and you will buy fakes if you are not careful. At present, the most popular and authentic brands sold online are often products produced by some professional manufacturers, whose brand awareness is not high, such as domestic polar, Snow Wolf, Kayven and American Camel. And some foreign brands such as Kellogg, Shayan, Royal, etc. These brands are moderately priced, well-made, professional and casual, and suitable for more occasions. Although not as good as those top brands, it is enough for ordinary outdoor lovers or daily use.

In short, jackets can be highly selective, and there is no need to focus only on top brands. It is true that top brands are good, but the price and professionalism are not available to everyone. There are many brands of jackets to choose from, as long as they suit your personal use.

Definition and function of jacket

First, we need to define a jacket. What kind of clothes can be regarded as a jacket?

This definition should start with the function of the coat. The coat is used to shelter from the wind and rain, so the fabric of the coat itself must have waterproof function. In addition, because the coat is designed for everyday wear, it is also important to meet the waterproof requirements. Fabric is not waterproof enough. When it rains, the rain will penetrate along the seams of the cloth, so all the seams must be sealed with glue. Therefore, we can define a jacket as: the fabric is waterproof and breathable, and there is glue at the seams.

Jacket fabric

Since the jacket is waterproof and breathable, the fabric is naturally not an ordinary fabric, and all the fabrics of the jacket are composed of several layers of materials.

Jacket fabrics are divided into two categories: two-layer glue and three-layer glue. The double-layer laminated fabric consists of an outer fabric and a waterproof and breathable film. Because waterproof and breathable films are generally made of polyester, just like the plastic bags we use, direct contact with the skin will be uncomfortable, so jackets with two layers of compound glue are generally lined. The lining is usually mesh cloth or thin polyester material. Since it is made of sandwiches, some clothes are simply filled with various warm-keeping materials, so that this jacket has the function of keeping warm while preventing wind and rain.

In fact, the appearance of the three-layer rubber sheath solves the problem of uncomfortable contact between the two-layer rubber sheath and the skin. In order to reduce the weight, a thin layer of gauze is directly laminated on the back of the two-layer laminated fabric, and there is no sticky feeling when it fits the skin. Generally, jackets filled with thermal insulation layer in the middle are laminated. If you don't need a warm layer, I suggest you buy a coat with three layers of glue.

What is a waterproof breathable film?

Waterproof and breathable sound like a contradiction, so how to achieve waterproof and breathable at the same time? As we know, the molecular volume of water in liquid state is about 20000 times larger than that in gas state. Since there is a difference of 10 thousand times, let's imagine that if there is a sieve, the size of the sieve hole is just between the diameter of water and steam. Then it can be done that only water vapor can pass through and liquid water can't. Therefore, almost all waterproof and breathable membranes adopt microporous structure. Take the most famous American GORE-TEX fabric as an example. This fabric is densely covered with as many as 9 billion holes per square inch. The diameter of these pores is 700 times smaller than that of liquid water molecules, but more than 20,000 times larger than that of gaseous water molecules. There are many kinds of fabrics on the market, in fact, the principle is basically the same, the difference lies in the aging resistance and air permeability of the fabric surface when it is wet or not.

The surface of the jacket outer fabric will be treated with splash-proof water when it leaves the factory, that is, water drops will roll down quickly like lotus leaves. The purpose is to prevent the fabric from absorbing water and increasing its weight and permeability, and also to keep the surface of clothes dry, which is beneficial to air permeability, because most waterproof and breathable films will lose their air permeability after the fabric itself is wet.
