1 Jackets are first of all the most important windproof function. It is also the first condition for keeping warm. Now the jacket has done it all. This is the most fundamental
2 The use of fabrics or coatings for jackets is not studied here, but if the waterproof can reach 10000mm-20000mm, the price may be more than 1500 yuan (single layer), which is 2-4 hours in heavy rain. It can be seen that even expensive jackets are far less waterproof than plastic cloth. Therefore, if you are not looking for lightweight, a raincoat is necessary.
3 The ventilation function is actually an important function second only to windproof. The breathability of jackets must be compared to other garments while ensuring warmth and waterproofness. However, the higher the permeability, the better. Helps wick away sweat and dampness.
Various fabrics and processes are different. High-end fabrics are generally thin film fabrics that are stretched by heating. The price is relatively high. The jacket made by Decathlon mentioned by the subject is very good in the ordinary field. The price is 200, the waterproof is 2000mm (small to moderate rain for 2-4 hours), and the coating should be used, so breathability and wind resistance should pass. Decathlon may also have some mid-to-high-end assault and sailing suits. However, although the sailing suit is completely waterproof, it is also completely airtight. Decathlon jackets are indeed more cost-effective. This is not a raincoat after all. Jackets are actually like panacea, sun-proof, wind-proof, warm, waterproof and wear-resistant. You have to be incomparable with a single specialty.
No matter how waterproof a jacket is, it can’t be better than a raincoat. This is the fundamental principle. A normal jacket can resist torrential rain for tens of minutes, and if it keeps dry inside, it is fine. No matter how high it is, the breathability of the raincoat cannot be seen. Even if it is moderately rainy, the fish will get wet in a few hours.
Therefore, when you go to the wild in the rainy season, a raincoat is a must-have item. There are special raincoats for the wild, which can cover the big bag on the back.
Jackets have a waterproof factor. Some fabrics can be waterproof 10,000 and breathable 10,000. Of course, the premise is what its testing specifications are. The testing specifications of the Japanese standard and the European standard are different. The European standard is higher. If it is waterproof, bad weather for a short time should be no problem, but if you go to the waterfall to test. No matter how good the jacket is, it can't hold it. Ordinary precipitation is fine. There is also a connection between water penetration and laminating technology. If the seam allowance is three-layer glue, the water resistance will be better.
Waterproofness and breathability are actually inversely proportional. The better the waterproofness, the worse the breathability—for example, raincoats, the better the breathability, the worse the waterproofness—you can imagine all kinds of quick-drying clothes. The waterproofness of the jacket depends on the fabric used. The ordinary waterproof coefficient is 2000-3000mm, and some waterproof coefficients even reach 5000mm-8000mm. Of course, in addition to waterproofing, the brand will also consider the breathability of the jacket, plus laminated tailoring Design and workmanship... In this way, a good jacket is very expensive.
